Code-pinned team memory for AI coding agents — typed artifacts, MCP-native, self-host.

Stores and retrieves typed artifacts as team memory for AI coding agents.

Pindoc

Code-pinned team memory for AI-assisted development. Agents write the durable record; humans review, discuss, and steer.

Pindoc is a self-hosted project memory system for teams working with AI coding agents. It turns useful agent discoveries into typed artifacts: decisions, debugging paths, task closeouts, verification notes, and code-linked analyses. Every artifact is scoped to a project area and pinned back to commits, files, URLs, resources, or related Pindoc artifacts.

It is still the wiki you never type into, but the point is not automation for its own sake. Pindoc keeps the parts of agent work that teammates and future agents can reuse.

Why It Exists

AI coding sessions are productive, but team context still falls through the cracks:

a debugging path dies with the terminal session,
the same decision is re-explained to every new agent,
useful analysis stays in one operator's chat instead of becoming team knowledge,
duplicate documents accumulate across wikis, issue trackers, PRs, and commit messages,
in real project environments, the person who finds a problem cannot always change the code immediately; structured evidence helps the team discuss and decide.

Pindoc turns agent work worth keeping into searchable, code-pinned team memory. The next teammate or coding agent can ask Pindoc what matters before it edits.

What Makes Pindoc Different

Collaborative memory layer: artifacts are written for teammates and future agents, not as private chat summaries.
Agent-only write surface: the Reader UI is for reading and review; durable writes go through agents.
MCP-native workflow: tools such as pindoc.context_for_task, pindoc.artifact.propose, and pindoc.task.queue regulate agent behavior instead of acting as a thin CRUD API.
Typed artifacts: Decision, Analysis, Debug, Flow, Task, TC, Glossary, and domain-pack types.
Code-pinned memory: artifacts can point to commits, files, line ranges, resources, URLs, and related artifacts.
Record-worthy by design: Pindoc avoids raw chat archives and keeps only decisions, analyses, debug paths, verification, and task context with future value.
Multi-project daemon: one /mcp endpoint can serve multiple projects; each tool call carries project_slug.
Self-host first: Docker Compose brings up Postgres, pgvector, the Pindoc daemon, and the Reader SPA.

Public Demo

A read-only public demo is a follow-up track and is not part of this OSS release. Until it ships, the README, docs/, and a self-hosted clone are the primary proof. Operators who want to evaluate Pindoc end-to-end run docker compose up -d --build and inspect their own artifacts.

The follow-up demo plan stays in Public Demo Plan for when a hosted instance is appropriate.

Quick Start

Prerequisites:

Docker 27+
2 CPU cores and 4 GB RAM recommended for local dogfood or small-team use
5 GB free disk recommended for Docker images, Postgres data, and the embedding cache; 2 GB is a light fresh-clone minimum
outbound HTTPS on first run so the bundled EmbeddingGemma model and runtime can be cached
Go 1.25+ only for host-native development
Node 20.15+ and pnpm 10+ only for web development outside Docker

The default Docker path includes semantic search through a bundled EmbeddingGemma Q4 ONNX provider, so no embedding sidecar is required. See System Requirements for minimum and optional deployment profiles.

bash

git clone https://github.com/var-gg/pindoc.git
cd pindoc
docker compose up -d --build

Open the Reader:

text

http://localhost:5830/

On a fresh instance, / first asks for the owner identity (display name and email), then routes to the first-project wizard. To open the project wizard directly after identity setup:

text

http://localhost:5830/projects/new?welcome=1

Repair Ownerless Projects From Older REST Builds

Older builds could create a project through POST /api/projects without a matching project_members owner row. After upgrading, repair any affected project by assigning the configured loopback owner:

sql

INSERT INTO project_members (project_id, user_id, role)
SELECT p.id, s.default_loopback_user_id::uuid, 'owner'
FROM projects p
CROSS JOIN server_settings s
WHERE p.slug = '<project-slug>'
  AND s.default_loopback_user_id IS NOT NULL
ON CONFLICT (project_id, user_id) DO UPDATE SET role = 'owner';

Connect an MCP Client

The Docker daemon exposes one account-level MCP endpoint:

jsonc

{
  "mcpServers": {
    "pindoc": {
      "type": "http",
      "url": "http://127.0.0.1:5830/mcp"
    }
  }
}

Project scope is not encoded in the URL. Agents pass project_slug on project-scoped tool calls. Workspaces generated by pindoc.harness.install store that slug in PINDOC.md frontmatter. pindoc.workspace.detect resolves the likely slug for the current workspace, but it does not mutate the daemon-wide PINDOC_PROJECT default. In a multi-project Docker daemon, keep passing the detected project_slug explicitly after the session sweep.

completeness=draft is a maturity/trust state, not an unpublished private draft. Accepted MCP writes are still published and Reader-visible when visibility allows. Use visibility=private or the review workflow for content that must not appear on the normal user surface.

Common Workflows

Ask an agent to start work with project context:

text

Use Pindoc context before editing. Find the current project, inspect assigned
Tasks, then implement the next acceptance item.

Typical MCP loop:

pindoc.workspace.detect
pindoc.task.queue
pindoc.context_for_task
code or doc work
pindoc.artifact.propose
update Task acceptance and closeout state

Asset uploads from Docker Desktop / Windows

pindoc.asset.upload(local_path=...) reads paths from the MCP server host/container, not from the Windows client. For Docker Desktop, copy the host file into the pindoc-server-daemon container first:

powershell

pwsh -File tools/push-asset.ps1 A:\path\image.png -ProjectSlug survival-manager

The script prints the JSON input for pindoc.asset.upload, including the container-local /tmp/pindoc-asset-upload/... path.

For Reader-visible inline images, two steps are intentionally separate:

Put ![alt](<asset.blob_url>) in body_markdown; this controls rendering.
Call pindoc.asset.attach with role="inline_image"; this records revision metadata and evidence.

Configuration

The default Docker path is single-user and loopback-only:

Variable	Default	Purpose
`PINDOC_DAEMON_PORT`	`5830`	Host port used by Docker Compose.
`PINDOC_PROJECT`	`pindoc`	Default project for unscoped reads/config.
`PINDOC_PUBLIC_BASE_URL`	`http://127.0.0.1:${PINDOC_DAEMON_PORT}`	Public base URL used in generated links and OAuth metadata.
`PINDOC_BIND_ADDR`	`127.0.0.1:5830`	Security intent. Non-loopback values require an IdP or explicit public unauthenticated opt-in.
`PINDOC_AUTH_PROVIDERS`	empty	Identity providers enabled for external requests. Current provider: `github`.
`PINDOC_ALLOW_PUBLIC_UNAUTHENTICATED`	`false`	Explicit opt-in for external exposure without an IdP. Use only behind a trusted network/reverse proxy.
`PINDOC_FORCE_OAUTH_LOCAL`	`false`	Development flag that routes loopback `/mcp` calls through OAuth bearer auth for local QA.
`PINDOC_ALLOWED_ORIGINS`	empty	Comma-separated CORS allowlist. Empty means same-origin only; set explicit origins for cross-origin frontends.
`PINDOC_DEV_MODE`	`false`	Development-only flag that permits wildcard CORS for local tooling. Do not enable on public instances.

Do not expose a writable daemon to the public internet without an identity provider. For a public read-only demo, keep /mcp and mutating HTTP routes blocked at the reverse proxy; see SECURITY.md and docs/22-public-demo.md. The daemon also sets baseline security headers itself, including nosniff, clickjacking protection, referrer policy, and hardened asset-blob CSP.

For a writable public or cross-device instance, follow docs/oauth-setup.md. It covers GitHub OAuth App setup, the ${PINDOC_PUBLIC_BASE_URL}/auth/github/callback callback rule, runtime MCP client registration, and local OAuth QA with PINDOC_FORCE_OAUTH_LOCAL.

Development

bash

# Run Go tests. Integration tests that need Postgres are skipped unless
# PINDOC_TEST_DATABASE_URL is set.
go test ./...

# Web checks.
cd web
pnpm install --frozen-lockfile
pnpm typecheck
pnpm test:unit
pnpm build

# Full image build.
docker build -t pindoc-server:local .

To test the OAuth bearer path locally while still connecting through 127.0.0.1, set PINDOC_FORCE_OAUTH_LOCAL=true; the daemon will warn on boot and require Bearer tokens for loopback /mcp calls.

On Windows hosts without a local C toolchain, run Go tests through Docker:

powershell

docker run --rm -v "${PWD}:/work" -w /work golang:1.25 go test ./...

Status

Pindoc is in active dogfood. The local self-host path, Reader UI, project/area model, artifact proposal flow, task queue, revision history, summaries, and real embedding provider path are implemented. The public OSS launch track is focused on first-run reliability, a read-only dogfood demo, CI, security docs, and clearer collaborative positioning.
