security-recipes.ai
Search CVEs. Remediate vulnerabilities with AI agents. Sourced facts stay
sourced, remediation stays bounded, and every plan carries verification,
rollback, and stop conditions — the live site's contract, and this repo's.
security-recipes.ai is an Eleventy site for
sourced CVE intelligence and evidence-gated vulnerability remediation that AI
agents can consume without inheriting deployment or production authority.
The project is intentionally narrow:
- a complete rolling Medium/High/Critical CVE database,
- evidence-qualified canonical CVE remediation records,
- practical security remediation recipes,
- prompt and rules-file examples,
- agent setup guides,
- MCP integration patterns,
- an optional read-only MCP server for recipe search and approved upstream MCP
context,
- a reusable GitHub Action
that turns this guidance into toggleable CI health checks.
It is not a scanner, ticketing system, SOAR platform, deployment tool, or custom
security toolkit. Existing security tools should produce the findings; this
site helps agents use the right remediation context and stop at the right time.
Start with the live CVE Database
for an exact vulnerability or the
AI Vulnerability Remediation Playbooks
for the evidence-to-patch workflow. Agent-specific guides cover
Codex,
Claude Code,
Cursor,
GitHub Copilot,
Devin,
Shiba Studio,
Hermes Desktop, and
OpenClaw.
The Visual Guide shows the complete
path from source qualification and search discovery to a bounded plan, proof,
rollback, and human review.
For the distinct problem of securing an agent system's identities, tools,
connectors, context, memory, runtime, and recovery controls, use
AI Agent Security.
Current product and workflow
Qualified search discovery
The complete catalog remains searchable, while public canonical CVE pages stay
limited to reviewed or evidence-qualified records. Those pages ship unique
search metadata, server-rendered core facts and affected-version evidence, one
remediation authority (stable reviewed guidance first, otherwise complete
source-linked AI enrichment), a short approval-gated AI implementation prompt,
canonical URLs, breadcrumbs, and Article/TechArticle structured data. The CVE database
describes the catalog as a Dataset; the remediation pillar exposes its visible
seven-step workflow as a HowTo. Year-partitioned CVE sitemaps contain only
indexable canonical routes, and the build fails when sitemap parity, canonical
ownership, crawl reachability, metadata limits, or same-origin links drift.
Indexability is also withheld from mass-templated recipe children. The 72
development code-hygiene recipes and 39 generated compliance-framework recipes
remain browsable from their canonical hubs with noindex,follow while they
share a common method. A bounded rendered-body similarity gate prevents a child
from re-entering sitemaps until its evidence, examples, and tests are materially
distinct. The hubs remain indexable and carry the shared discovery context.
After an SEO-bearing release, the public revision must match the merge commit
before sitemap submission or URL inspection. The
Caddy deployment guide
documents the DNS-verified Search Console handoff, priority live-URL checks,
sitemap submission, indexing requests, and query monitoring. Submission is a
discovery hint; it does not guarantee indexing or a particular ranking.
The remediation pillar also records a public repository example for
CVE-2026-13149 in brace-expansion.
It ties the dependency-only change to the
reviewed pull request,
tests, advisory evidence, and recovery path while explicitly separating the
same PR's unrelated Fail2Ban work.

What this project is for
AI coding agents can help close security findings when their work is bounded:
one finding, one recipe, one reviewed output.
security-recipes.ai helps teams answer:
- Which recipe matches this finding?
- Which prompt should the agent use?
- Where do I put the instructions for Copilot, Claude, Cursor, Codex, or Devin?
- Which MCP servers should the agent read for advisory, scanner, repository, or
runbook context?
- What should the PR or triage note include before a reviewer trusts it?
What ships
- Eleventy documentation site (fast static builds, no Go toolchain).
- CVE-first observatory home page and data-first CVE database.
- Recipe hubs for dependency, SAST, sensitive-data, base-image, CVE, and
default-hardening remediation.
- CVE intelligence intake policy, prompt, fixtures, and evaluator for routing
advisory signals before an agent patches.
- A complete rolling ten-year Medium/High/Critical CVE catalog composed from
integrity-verified NVD JSON 2.0 feeds, CISA KEV metadata, and every applicable
vetted remediation archetype. Only reviewed
stable Markdown pages override
that conservative baseline.
- An integrity-hashed search allowlist that publishes canonical CVE pages only
for reviewed stable Markdown or AI enrichment that passes the deterministic
recipe-ready evidence contract. The full database remains searchable even
when a record is not eligible for search indexing.
- A versioned seven-phase agentic change contract for every catalog CVE:
discover, assess, mitigate, remediate, verify, rollback, and triage. Each
action declares likely file targets, mutation and approval boundaries,
required evidence, outputs, and failure behavior without guessing a patch or
fixed version.
- A structured compliance library spanning 39 security, privacy, assurance,
resilience, and software-supply-chain frameworks without reproducing
licensed control text. Its framework hub is the search surface; templated
child assessments remain
noindex,follow until differentiated.
- A 72-recipe code-hygiene library covering cross-language and ecosystem-
specific audit, remediation, verification, and stop-condition workflows.
Its development children remain
noindex,follow while their bodies share a
generated template.
- Recipes with existing prompt collections preserved.
- Agent setup guides for GitHub Copilot, Claude, Cursor, Codex, and Devin.
- MCP integration guidance for public and organization-approved security data
sources.
- Optional read-only FastMCP server in
mcp_server.py for recipe search,
retrieval, and opt-in upstream MCP context.
- Docker and Docker Compose configuration for local or droplet hosting.
- Helper scripts for site maintenance, validation, imports, and deployment.

The Python suite is an optional execution companion to the documentation. It
can inspect a bounded workspace, select any of the 75 remediation playbooks,
create a durable run packet, record integrity-hashed evidence, and verify the
packet before agent or reviewer handoff. It remains local and conservative: it
does not merge code, deploy changes, or call external systems on its own.

The repository also includes domain-specific generators and evaluators for
playbooks that need richer evidence packs or runtime policy decisions. The
site and JSON registry remain useful without Python; the tools make the same
workflow contracts directly executable by CI, orchestrators, and approved
coding agents.
Deployment helpers worth knowing:
scripts/setup_digitalocean_droplet.sh: Ubuntu droplet bootstrap with
Docker, host hardening, and optional Caddy-managed HTTPS.scripts/configure_nginx_letsencrypt.sh: host nginx reverse proxy setup for
teams that want Let's Encrypt on nginx instead of Caddy.README.nginx-letsencrypt.md: operator-focused walkthrough for the nginx
deployment path.
Recommended operating model:
- Let existing SCA, SAST, secrets, CI, cloud, and ticketing systems produce
findings.
- Attach a matching security-recipes.ai recipe and prompt.
- Let the agent read only the files and MCP context needed for the finding.
- Require tests and human review before merge.
- Keep broad automation, write access, and deployment outside the first loop.
The site is a guidebook for remediation work: recipes, prompts, agent setup,
MCP/API integration notes, and review patterns. Runtime automation belongs in
the user's approved agent host, CI system, ticketing workflow, or scanner
platform rather than a site-hosted chatbot.
Python tools in scripts/, tools/, and mcp_server.py support maintainers
and self-hosters with playbook execution packets, evidence verification,
domain-specific evaluation and generation, validation, advisory import,
recipe search, and optional read-only MCP access.
Optional MCP server
The MCP server is read-only by default. Its baseline role is to let
MCP-compatible agents search and retrieve recipes. Self-hosted deployments can
also configure it as a context hub for approved upstream MCP servers without
putting those credentials into the public site.
Retrieved context never grants mutation authority. Any connector that can
change repositories, tickets, secrets, deployments, or production systems must
be configured and approved separately by the calling host.
Common tools:
recipes_searchrecipes_listrecipes_getrecipes_cve_catalog_inforecipes_cve_searchrecipes_cve_getrecipes_match_findingrecipes_playbooks_listrecipes_playbook_getrecipes_playbook_planrecipes_mcp_upstream_serversrecipes_mcp_upstream_toolsrecipes_mcp_upstream_callrecipes_mcp_upstream_context
The MCP server accepts both generated recipe feeds:
/api/recipes.json is the preferred agent feed with category, severity,
CVE/GHSA, ecosystem, and handoff metadata./recipes-index.json remains supported for legacy consumers./recipes-browser.json is the compact interactive-library feed. The
/recipes/ page server-renders 18 crawlable recipe cards and an exactly
matching hydration seed, then requests the complete feed only when a visitor
focuses search, filters, sorts, follows a filtered URL, or loads more.
The complete CVE catalog is also available without MCP:
/api/cve-catalog/manifest.json declares the exact date/severity policy,
source hashes, coverage counts, and shard inventory./api/cve-catalog/runtime-summary.json is the small browser bootstrap with
coverage totals and content-derived cache versions for every runtime asset./api/cve-catalog/index.json is a small manifest for the complete
publication-year partitions under /api/cve-catalog/indexes/. Offline
consumers can fetch only the years they need; neither a browser page load
nor an exact MCP lookup parses those partitions./api/cve-catalog/search is the bounded, same-origin broad-search endpoint.
It is pinned to the shard-set revision declared by runtime-summary.json,
rate-limited at nginx, and returns at most 100 previews. The production MCP
image serves it from a read-only SQLite FTS database built and whole-file
verified against the same manifest. Focus alone and an incomplete
CVE-YYYY-NNNN identifier make no search request./api/cve-catalog/records/{cve} is the bounded, same-origin exact-record
endpoint. Every request pins the shard-set revision, and the MCP service
verifies and opens only the one deterministic shard containing that CVE.
Current browsers use this endpoint instead of learning the shard namespace./api/cve-catalog/browser-index.json.gz remains for one compatibility
window when an older runtime summary does not declare the search and record
APIs. Current browsers do not download it when the APIs are declared, so
visitors no longer pay the complete-corpus transfer or memory cost.- Canonical CVE pages server-render their overview, affected-version evidence,
selected remediation authority, AI implementation and verification handoff,
sources, provenance, citation, and schema. They do not embed or hydrate the
catalog application. A compact link to the exact gzip JSON Lines shard remains
available for machine-readable provenance without adding a browser fetch.
/api/cve-catalog/search-indexable.json is the compact, integrity-hashed
allowlist for canonical CVE pages, related-CVE links, and search discovery.
Its policy accepts only reviewed stable Markdown or complete AI enrichment
that passes the deterministic recipe-ready evidence contract. Every browser
result links to its local /cve/<ID>/ record. Allowlisted records are
materialized as indexable static pages; all other records use the bounded
runtime renderer with noindex,follow and retain their official CVE.org
source in the record./api/cve-catalog/archetypes.json contains the reviewed remediation
contracts used to compose a conservative recipe for every catalog record.
It also contains the versioned agentic action schema and ecosystem-specific
file-target hints shared by the browser and MCP server.- Each partition maps every in-scope CVE to its integrity-hashed compressed
JSONL shard. Shard records contain CVSS, CWE, bounded CPE, reference, and KEV
provenance for exact-CVE retrieval.
- To keep records bounded, a shard stores at most 12 vulnerable CPE/version
rows together with the source match total and an explicit truncation flag;
consumers must follow NVD/vendor evidence when that flag is set.
Canonical CVE pages use one primary-reference set for the visible source list
and structured-data citations. Raw generated records admit NVD, CVE.org,
scoped CISA KEV records, and source-linked vendor advisories, patches, release
notes, or mitigations; broken, third-party-only, exploit-only, and generic
vulnerability-database links are not promoted automatically. Stable reviewed
Markdown can deliberately cite additional HTTPS evidence in its References
section. When remediation spans several supported branches or product
families, the displayed action preserves every trusted fixed-release claim
instead of collapsing the guidance to one incomplete upgrade.
Development and catalog-owned stable CVE Markdown emit no standalone page in
the pure static build and are excluded from Eleventy and generic recipe/search
feeds, tag pages, RSS, and the sitemap. The three pre-catalog historical stable
recipes remain ordinary rendered content.
Production can retain a legacy recipe URL as a redirect to the canonical CVE
route through nginx and the MCP-backed landing service. Use the dedicated
catalog or recipes_cve_* MCP tools for complete discovery.
The browser's exact-ID path and revision-pinned search API cover every in-scope
Medium, High, and Critical record declared by the manifest. The MCP server
exposes the same SQLite-backed coverage through recipes_cve_search; a successful
recipes_cve_get returns the normalized source record, source identifiers and
references, applicable archetypes, composed remediation contract, and a
self-contained agentic_change_plan. The plan expands each mitigation and
remediation instruction into ordered code/file operations with verification,
rollback, evidence, approval, and triage requirements. It also preserves
explicit CPE truncation metadata when the source match set exceeds the bounded
record.
Daily CVE synchronization and optional AI enrichment
.github/workflows/cve-catalog-sync.yml runs every day at 09:23 UTC and can
also be dispatched manually. It verifies and joins the NVD JSON 2.0 annual
feeds and CISA KEV catalog, regenerates every catalog index/shard, validates the
result, refreshes recipe-derived deterministic evidence in dependency order,
runs the catalog tests, and opens or refreshes
automation/cve-catalog-sync as a pull request to the default branch.
Repository Settings > Actions > General > Workflow permissions must allow
GitHub Actions to create pull requests for first-run PR publication.
Set CVE_AUTO_MERGE_ENABLED=true to deliver a safety-approved catalog PR after
its exact head revision passes the dedicated validation workflow. When
CVE_AUTOMATION_APP_CLIENT_ID and the CVE_AUTOMATION_APP_PRIVATE_KEY secret
are configured, the workflow prefers that GitHub App identity so ordinary PR
and main-branch Build runs fire naturally. Without App credentials, the
workflow remains automatic: after the guarded GITHUB_TOKEN merge it verifies
that the returned merge SHA is still current main, then dispatches the real
build.yml workflow with that exact SHA. The production deploy gate recognizes
only those CVE-qualified Build dispatches, so scheduled monitors and unrelated
manual workflows cannot deadlock or satisfy a release.
The source sync does not require a secret. Leftover-gold review, content
refresh, AI maintenance, AI issue maintenance, and this repository's
security-health action also use Grok. Add one Actions secret named
XAI_API_KEY (the official xAI environment variable; do not use
GROK_API_KEY):
gh secret set XAI_API_KEY --repo stevologic/security-recipes.ai
The workflow defaults to xAI's grok-4.6 Responses API model and at most 20
new or source-changed records per run. The scheduled queue is
derived from the tracked NVD/CISA catalog: a candidate must have a valid tagged
vendor advisory, patch, release-note, or mitigation URL. Source-complete records
remain eligible because they still need a sourced remediation synthesis; within
each KEV and severity band they rank ahead of records with deterministic source
gaps, followed by affected-product/version evidence and recency. This uses the
existing daily request budget and does not require an additional manual run.
Both the model and limit can be changed with optional Actions variables; the
enrichment limit is hard-bounded from 0 to 50:
gh variable set XAI_MODEL --body "grok-4.6" --repo stevologic/security-recipes.ai
gh variable set XAI_ENRICHMENT_LIMIT --body "20" --repo stevologic/security-recipes.ai
AI output is supplemental and explicitly labeled. It uses strict structured
output, only cites URLs actually returned in the Responses API web-search
provenance, and is stored reproducibly in data/cve/ai-enrichments.json. A
complete enrichment becomes a CVE-specific Markdown draft only when a separate
gate finds claim-level affected-product, exposure, remediation, and
verification evidence tied to the exact URL of a tagged trusted advisory
reference. Every required claim must independently meet that rule, and every
generated recipe requires a cited, concrete fixed-version claim.
Cached enrichment is re-evaluated instead of becoming permanent: recipe-ready
entries become refresh candidates after 30 days, KEV entries after 60 days,
and other complete/not-specific or insufficient-evidence entries after 180
days. A manually prioritized CVE forces a refresh inside the existing request
cap. The last valid cached result stays attached if that refresh fails; an
invalid source fingerprint remains fail-closed. The synchronization report and
automation-health summary expose refresh-due and manually prioritized counts.
Eligible drafts are written as maturity: development files named
content/recipes/cve/ai-enrichment-cve-*.md. They stay outside generic recipe
discovery and never override a stable reviewed recipe. A human reviewer can
set ai_enrichment_review_status: human-reviewed-development-draft to withhold
an otherwise evidence-ready enrichment from public remediation authority, or
ai_enrichment_review_status: approved-for-ai-authority to approve that use.
Unannotated generator-owned drafts retain the automated evidence gate, while
stable Markdown always wins. The ownership ledger
in data/cve/ai-generated-recipes.json records each generated file hash;
automation may refresh or remove only an untouched hash-matching draft. A human
edit, or any existing human development/stable recipe for the same CVE, makes
that Markdown human-owned and blocks automated replacement. AI generation never
changes source CVSS/KEV facts, affected-version data, archetype selection, or
reviewed stable Markdown. A
missing key, API refusal, timeout, or rate limit does not block the NVD/CISA
refresh; calls stop after three consecutive failures or a 15-minute budget,
and valid cached enrichments remain attached. A manual run may prioritize named
CVEs, but those IDs consume slots inside that run's existing cap and never
bypass the recipe-ready evidence gate:
gh workflow run cve-catalog-sync.yml --ref main \
-f ai_enrichment_limit=20 \
-f priority_cve_ids="CVE-2026-58644,CVE-2026-56164"
A manual dispatch is an additional workflow run and can therefore make
additional requests; it is not needed for the daily deterministic queue. A
manual run on a non-default branch uploads its enrichment cache, ownership
ledger, and generated drafts as a short-lived workflow artifact for review.
.github/workflows/leftover-review.yml runs every day at 13:17 UTC and
live-verifies leftover-gold CVE leftovers against GitHub Advisories and NVD.
Leftover-gold criticals and highs drain first. After those close, each run
reviews up to 25 leftover-gold medium and low pages, records completed IDs
in data/cve/leftover-review-state.json, and opens a labeled auto-merge PR.
The leftover-review job uses the Grok Build CLI with XAI_API_KEY and
no-ops when that secret is missing or the leftover-gold queue is empty.
The runtime paths are deliberately bounded for catalog-scale traffic:
- the hub bootstraps from the compact runtime summary, exact lookups call the
revision-pinned same-origin record API, and title/product/vendor/filter
search calls the search API only after explicit search intent;
- broad search returns at most 100 previews from immutable read-only SQLite,
has a three-second HTTP boundary, and never decodes the complete catalog in
a visitor process or on the browser main thread;
- the exact-record service verifies and opens one shard per request; MCP exact
retrieval uses the same shard-only path, while non-exact text search uses the
manifest-pinned SQLite database behind a dedicated executor, bounded
admission queue, query deadlines, and nginx rate limit;
- immutable browser cache keys come from the declared record/search contract,
archetype hash, and shard-set revision rather than an upstream timestamp.
The implemented build boundary, exact-shard delivery model, evidence-gated SEO
policy, SQLite search runtime, and remaining artifact-publication migration are documented in
CVE scale architecture.
The production image builds the SQLite artifact once in its cached image layer,
records its independent SHA-256 sidecar, and validates schema, catalog revision,
record count, manifest digest, file digest, and representative FTS postings at
startup. RECIPES_MCP_EAGER_CVE_SEARCH now applies only to the legacy local
fallback when no SQLite path is configured. For sustained search traffic, run
multiple paired MCP instances; exact shard reads remain isolated from the
bounded text-search executor and queue.
Run npm run icons after changing the site mark. It regenerates the opaque
Apple touch icon and the 192/512/maskable installed-app assets checked by the
production performance gate.
Production builds precompress large JSON/XML feeds for nginx gzip_static,
validate stable/draft discovery boundaries, and enforce payload/file-count
budgets with npm run check:performance.
Run it with Docker:
docker build -f Dockerfile.mcp-server -t security-recipes-mcp .
docker run --rm -p 8123:80 security-recipes-mcp
Connect an MCP client to:
http://localhost:8123/mcp
Run it locally with Python:
python -m venv .venv
source .venv/bin/activate
pip install -r requirements-mcp-server.txt
python mcp_server.py
Windows PowerShell activation:
.\.venv\Scripts\Activate.ps1
python mcp_server.py
Run the site locally
Prerequisites:
- Node.js
>= 20
- Python
>= 3.10 with requirements-mcp-server.txt installed for the
production npm run build CVE prerender step
- Git
python -m pip install -r requirements-mcp-server.txt
npm install
npm run serve
Open:
npm run serve watches for changes and rebuilds incrementally. A one-off
production build is npm run build (output lands in public/). The build
performs a Python/dependency preflight before deleting an existing output and
then uses the same CVE renderer as the MCP runtime. Eleventy deliberately does
not passthrough-copy static/api/cve-catalog/: after page materialization, a
bounded post-build step rejects links, orphan files, unsafe paths, and
manifest byte/hash mismatches before installing that catalog subtree. Static
assets outside the catalog, including root dotfiles, retain normal passthrough
behavior.
For an isolated catalog build, set
SECURITY_RECIPES_CVE_CATALOG_ROOT to its absolute publication directory.
Eleventy data, qualified-page materialization, and the validated catalog copy
all use that same root. npm run serve does not rerun the materializer or
catalog copy, so run npm run build once first when you need canonical
/cve/<ID>/ pages and the catalog API tree in the development server; later
incremental rebuilds retain those post-build outputs.
Docker Compose
Create an environment file:
Start the stack:
docker compose up -d --build
Use the Docker Compose v2 plugin (docker compose). The legacy Python
docker-compose v1 package is not supported for this stack; it can crash with
KeyError: 'id' while following logs or KeyError: 'ContainerConfig' while
recreating containers on newer Docker Engine releases.
On Ubuntu/Debian hosts, install Compose v2 and a compatibility shim with:
sudo bash scripts/install_docker_compose_v2.sh
Default routes:
site: http://127.0.0.1:8080/
agent recipe feed: /api/recipes.json
MCP endpoint: /mcp
The Compose stack keeps the public site and its dynamic CVE/MCP renderer in
matching blue/green pairs:
security-recipes / mcp-server-blue: blue site and renderer.security-recipes-green / mcp-server-green: green site and renderer.mcp-server: transitional singleton retained for the first paired rollout
and backwards-compatible manual Compose workflows. It reads the
locally built site feed at http://security-recipes/api/recipes.json, so a
fork or droplet serves its own recipes instead of depending on the public
production index.
deploy.sh starts and revision-verifies the withdrawn slot's MCP container
before its site container, validates a canonical CVE directly, and only then
admits the pair to Caddy. Manual Compose startup retains the singleton default
so the first rollout remains compatible with the previously installed script.
For an nginx or Caddy reverse proxy with Let's Encrypt, keep Docker bound to
loopback and let the proxy own public ports 80 and 443:
SECURITY_RECIPES_HTTP_PORT=127.0.0.1:8080
Then proxy to:
location / {
proxy_pass http://127.0.0.1:8080;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
If you want a turnkey host nginx + Let's Encrypt setup, run:
sudo bash scripts/configure_nginx_letsencrypt.sh \
--domain security-recipes.ai \
--email admin@security-recipes.ai
The full operator guide lives in README.nginx-letsencrypt.md.
DigitalOcean droplet
For a fresh Ubuntu droplet, use the helper script:
sudo bash scripts/setup_digitalocean_droplet.sh \
--domain security-recipes.ai \
--email admin@security-recipes.ai
The script installs Docker/Compose, configures a locked app user, enables basic
host hardening, starts the Compose stack, and can place Caddy in front for
HTTPS. It also enables a Caddy-aware Fail2Ban jail: five final HTTP 404
responses for high-confidence exploit-probe paths (for example .env, Git,
WordPress, phpMyAdmin, or PHPUnit probes) from one client within five seconds
block that address from the site's TCP and HTTP/3 ports for one hour, after
which access is restored automatically. Ordinary missing pages, CVE-shaped
misses, and archive pagination misses do not consume the ban budget.
Point both the apex and www DNS records at the Droplet before setup. Managed
Caddy obtains certificates for both names and permanently redirects www to
the apex canonical host; redirecting only at HTTP would leave HTTPS crawlers
unable to complete the TLS handshake. The same stack can serve
security-recipes.si and www.security-recipes.si from those upstreams
(SECURITY_RECIPES_MIRROR_DOMAIN); visible brand chrome follows the request
Host, while SEO canonicals stay on https://security-recipes.ai/. See
README.caddy-deploy.md.
Existing Droplets need this one-time, idempotent activation after deploying
the commit that contains the jail:
sudo bash scripts/configure_caddy_404_ban.sh
sudo fail2ban-client status security-recipes-caddy-404
If the Droplet still runs bundled Caddy with the old named log volume, first
set SECURITY_RECIPES_TRAFFIC_LOGS_SOURCE=/var/log/caddy in .env, then
recreate only Caddy once during a maintenance window:
docker compose --profile caddy up -d \
--no-deps --force-recreate --pull never caddy
sudo bash scripts/configure_caddy_404_ban.sh
The filter uses Caddy's structured client_ip, not spoofable forwarding
headers or User-Agent values. If the origin is later placed behind a CDN or
load balancer, move the ban action to that provider's WAF/API; an origin
firewall cannot directly block an end client whose packets arrive from a
trusted proxy.
The jail does not trust Googlebot User-Agent strings. Before counting a public
client, it performs Google's reverse-then-forward DNS check: the PTR hostname
must be under googlebot.com, and resolving that hostname must return the same
IP. Results are cached by IP for one hour; lookup errors and the five-second
resolver deadline fail closed, so an unverified client remains subject to the
scanner-path 404 budget.
For a fully Compose-managed Caddy deployment, Fail2Ban can instead run in the
stack. Set DEPLOY_COMPOSE_FAIL2BAN=true in .env and keep Caddy's log source
on the default caddy_logs volume (or a host bind). On its next run,
deploy.sh pulls, starts, health-checks, and subsequently updates the Fail2Ban
container. It also initializes Caddy's access-log file before starting the jail
because Fail2Ban requires the configured file to exist. To start it manually
without waiting for a deployment, use:
docker compose up -d caddy fail2ban
docker compose exec fail2ban fail2ban-client status security-recipes-caddy-404
The container shares the host network namespace and has only the
NET_ADMIN/NET_RAW capabilities required to apply the jail's nftables rules
to host and Docker-forwarded web traffic. Do not enable the Compose jail while
the host security-recipes-caddy-404 jail is active; choose one owner for the
firewall rules. This mitigates repeated application-layer 404 scanning, but it
does not replace upstream volumetric DDoS protection or request rate limiting.
When the option is false, deploy.sh does not require the host fail2ban
package; host-managed installations remain the responsibility of the droplet
setup and scripts/configure_caddy_404_ban.sh workflows.
If you prefer nginx instead of Caddy on the droplet, bootstrap the host without
the proxy and then run the nginx helper:
sudo bash scripts/setup_digitalocean_droplet.sh --no-caddy
sudo bash scripts/configure_nginx_letsencrypt.sh \
--domain security-recipes.ai \
--email admin@security-recipes.ai
For a local-only or pre-proxied droplet:
sudo bash scripts/setup_digitalocean_droplet.sh --no-caddy --no-firewall --no-upgrade
docker compose up -d --build
If a previous docker-compose v1 run failed with KeyError: 'ContainerConfig', upgrade Compose and remove the stale project containers
before recreating the stack:
sudo bash scripts/repair_docker_compose_containerconfig.sh
hash -r
command -v docker-compose
docker-compose version
Production deploys pull commit-addressed site and MCP images published by the
required GitHub Actions Build workflow on main and serve them at
https://security-recipes.ai/. The same timer also deploys development
images to https://dev.security-recipes.ai/. The Droplet does not run Node,
Eleventy, pip, or Docker image builds during a deploy, which keeps deployment
within a 1 CPU / 2 GB memory envelope.
One-time paired MCP deployment upgrade
Before the first deployment that introduces the paired MCP services, update
only the deployment script and then run it. An already-running older
deploy.sh process was parsed before the paired Compose file existed and would
otherwise recreate the live singleton MCP during that one rollout:
git fetch origin main
git checkout origin/main -- deploy.sh
bash deploy.sh
The new script leaves the live singleton untouched, prepares the inactive MCP
and site together, and switches them as one unit. After this one-time step, the
existing bash deploy.sh cron entry needs no change.
The first successful main workflow creates two GHCR packages. Make them
public, or authenticate the root account used by the deployment service with a
fine-grained token that can read packages:
printf '%s' "$GHCR_READ_TOKEN" |
sudo docker login ghcr.io --username stevologic --password-stdin
MCP integration philosophy
Use MCP to give agents context, not unchecked authority.
The CVE MCP tools only return plans and evidence; they do not edit a repository
or change an environment. An approved agent host may apply the returned plan,
but it must first prove the affected surface and actual repository paths,
preserve unrelated changes, obtain any declared production/external approval,
and retain a mechanically usable rollback. A likely file glob is a discovery
hint, never proof that a file is vulnerable or permission to modify it.
Within each action, only effective target_kinds are default candidates.
archetype_target_kinds are context, not authorization; conditional targets
require proof that the repository owns the affected implementation, while
prohibited targets must never be edited. Firmware and binary targets mean an
authoritative reference, pin, replacement, policy, inventory, source, or build
change—never patching vendor artifact bytes.
NVD/CNA descriptions, advisories, links, patches, issue comments, release
notes, and proof-of-concept content are untrusted evidence. Agents may extract
corroborated vulnerability and version facts from them, but must not execute or
follow embedded instructions or commands.
Good context sources include:
- official GitHub MCP capabilities for repository and code-security context,
- Semgrep and Snyk agentic/MCP integrations where approved,
- OSV, GitHub Advisories, deps.dev, package registries, and NVD-backed mirrors,
- SARIF, SBOM, CI, ownership, and internal runbook sources,
- read-only documentation connectors.
Write-capable connectors deserve separate review. Ticket creation, branch
mutation, deployment, secret rotation, cloud changes, and SOAR actions should
not be enabled just because an agent can read a recipe.
Contributing
Contributions should improve the recipe library:
- new remediation recipes,
- better prompts,
- clearer agent setup,
- MCP integration examples,
- reviewer checklists,
- documentation fixes.
