Termada
Persistent, policy-controlled missions for AI agents operating real environments.
Termada is a single-binary, local-first runtime that sits between an AI agent and
the terminal, locally or over SSH. The agent talks to it over the
Model Context Protocol and gets a sturdy
toolset instead of a raw shell: bounded exec_run waits, persistent sessions
that keep cwd/env, async jobs with streamed output, PTY input for interactive
prompts, and structured results β while you watch and control active jobs from a
live dashboard with a job kill-switch and an approval queue. Mission Control
adds a durable goal, GPT/Codex-authored plan, runtime-verified steps, interruption
recovery, and an exportable evidence report around that execution.
The live dashboard: every session is a real terminal you can watch and take over β block or pause the agent, type in yourself β beside the agent panel, policy management, a tamper-evident History, and a Stop-All active-job kill-switch.
Why
Handing an AI agent a raw shell is fragile and opaque: a command blocks on a
prompt and the agent hangs; cd and exported env vanish between calls; long
builds flood the context window; and you can't see β let alone stop β what's
running. Termada replaces the raw shell with a runtime that is reliable for
the agent and transparent for you:
- Reliable for the agent β blocking
exec_run calls use bounded wait budgets
and return structured output; sessions persist cwd/env; long jobs run async
and stream incrementally instead of dumping; interactive prompts are answerable.
- Transparent for you β one dashboard shows every agent and every session as
a real terminal; controlled actions matched by
confirm wait for your approval; one
button installs a short-lived action admission barrier, requests cancellation
of active gateway executions, signals active engine jobs and closes forwards;
remote/provider effects still require terminal verification or reconciliation.
- Accountable as a mission β an agent's plan, real commands, approval
decisions, verification jobs, outcome, and audit anchors stay together. A plan
step cannot pass without a real mission job that Termada observed exiting with
code zero.
Mission Control
For a concrete operational outcome, Codex or another MCP agent starts with
mission_create(goal, plan). Termada allocates a dedicated persistent session;
normal exec_* calls keep using the same policy, approval, PTY/SSH and audit
paths. The agent attaches each successful job_id with mission_update, then
exports mission_report.
The report separates runtime-observed evidence from agent notes, includes exact
audit sequence/hash anchors, and returns a SHA-256 recorded in the audit. If the
daemon restarts, a non-terminal mission becomes interrupted; mission_resume
creates a fresh session attempt instead of pretending PTY state survived.
Run the isolated real-execution demo:
./demo/mission-control/run.sh
It starts a broken loopback HTTP service and a separate demo daemon. The
protected repair genuinely changes service state and waits for a human approval;
the final probe must observe HTTP 200. See
demo/mission-control and the
2:40 demo script.
Features
Execution engine
- Persistent-shell sessions over a PTY that keep
cwd, env, and venv between commands.
- Async jobs:
exec_start β job_id; poll incrementally by a stable cursor, with sequential bounded pages, a full status state machine and structured errors.
- Answer interactive prompts (
exec_write, with secret redaction). Local PTY
jobs support process-group signals/kill; remote SSH interrupt/kill requests
are best-effort Ctrl-C, not a guaranteed force-kill.
- Clean output: stateful ANSI/VT stripping, CR-collapse, bounded retention, best-effort secret redaction.
Live control & observability
- A long-lived daemon with a control plane over a Unix socket;
serve --stdio is a thin shim that proxies MCP to it β so multiple agents share one daemon and one dashboard.
- Web dashboard where each session renders as a real terminal (xterm.js, streamed over SSE) with operator take-over: type into a job's PTY, hold the agent's input, or pause its output.
- Workspace labels, bounded state bootstrap, cursor-resumable live updates,
English controls and responsive desktop/mobile navigation.
- Approval queue, activity feed, policy/server management, and a Stop-All
cancellation barrier for admitted actions, active engine jobs and forwards.
- A TUI (
termada top) and a full inspection CLI.
- Synchronously recorded, hash-chained, best-effort-redacted audit log.
termada audit verify verifies the continuous chain across rotated segments.
Mission Control
- Durable, owner-scoped missions with a goal, up to 24 plan steps, dedicated
session, multiple resume attempts, bounded evidence timeline and terminal
outcome.
- Runtime enforcement for passed steps (
job_id from a mission session,
status=exited, exit_code=0) and refusal to succeed while jobs remain active.
- Mission-first desktop/mobile dashboard with pinned approval, stale/offline
states, compact plan/evidence views and Markdown report download.
Security
- Policy engine: every argv word is shell-quoted; allow / deny / confirm matching sees leading assignments, absolute paths, Darwin case variants, known wrappers and explicit shell payloads. Shell scripts/stdin/interactive shells and ambiguous compound commands fail closed when deny/confirm rules exist. The structured policy additionally matches authenticated principal, tenant, typed action/resource/context, risk and reversibility. Every controlled action that resolves to
confirm parks in the durable operator queue, times out to deny, and can execute only when the caller retries the exact approved action id.
- One canonical gateway covers every public side-effect route: current-policy
recheck, one-use approval consume, atomic budget authorization, durable intent,
provider outcome and explicit
outcome_unknown reconciliation state.
- Policy-owned budgets cover operations, runtime, monetary amount, tool/model
cost, production changes and post-outcome failures at exact global, tenant,
principal or recipient scopes.
- age-encrypted vault (no CGO); vault APIs never return secret values to agents.
Values are injected daemon-side and registered for best-effort output
redaction.
- Per-agent quotas and owner isolation for jobs, sessions, session-scoped remote
file operations and forwards. Sessions and pending confirmations are capped
at 32 per owner and 128 total; live forwards at 16 per owner and 64 total.
Local host paths remain a shared OS/filesystem boundary. Set
security.identity_mode: strict in production: every configured agent must
have an existing assigned policy and authenticate with either a unique strong
static token or an explicitly enabled, offline-verified short-lived
agent_identity JWT. Tokenless, unknown and policyless callers fail closed.
A strict policy without structured rules also denies every command that lacks
an explicit legacy allow match; deny/confirm gates take precedence.
development retains self-asserted ids for trusted local clients and is the
compatibility default for older configs that omit the field.
- Optional
security.run_as drops local shell processes to a dedicated uid and
disables daemon-privileged local file tools and daemon-environment inheritance;
use commands inside that dropped session for local file access. Remote SFTP
remains available.
- Every TCP
/api/* request and /metrics requires either the dashboard token
or an enabled, pinned-JWKS-verified human JWT. Operator-only Unix-socket routes
similarly require either a verified human JWT or the separate cli.token used
by the local CLI.
- Optional pinned-JWKS operator identity binds subject, tenant, roles,
delegation and verified MFA to approvals; policy can require role quorum,
distinct approvers and requester exclusion. Optional Ed25519 audit anchoring
exports signed fsynced chain heads through a durable HTTPS outbox.
Remote & fleet
- Persistent remote SSH sessions with reconnect β a dropped link is
re-dialled as a fresh shell so the session can serve new commands. The
authorized name, host, port, user, tags and keyed vault-reference binding stay
pinned, so inventory edits cannot retarget an approved or live session. Prior
cwd/env are lost; an in-flight job becomes
orphaned, and its uncontrolled
remote process may still continue. Verify remote state before retrying it.
fleet_run across servers by name or tag with best-effort-redacted,
structured per-server results. Commands must be non-empty argv arrays and run
under a shared daemon-wide ceiling of five concurrent fleet targets; a call
may request less. One call matches at most 256 targets and returns at most
2 MiB of aggregate result text. SSH uses vault creds, ssh-agent, or on-disk keys, with
serialized, fsynced TOFU host-key pinning that fails closed on a malformed
known_hosts file.
- Owner-scoped local-to-remote port forwards. Opening one is policy-gated and
rolled back unless its start audit record is durable; listeners are
loopback-only and bounded to 64 simultaneous connections per forward.
Operations
- Crash recovery (jobs persist; running jobs come back as
orphaned), bounded local-FS snapshots/undo, desktop notifications and outbound-only Telegram notifications.
- A typed adapter SDK provides durable
prepare β execute β verify β compensate/reconcile phases, provider
idempotency keys, secret-free receipts and restart recovery. Generic shell and
plugin effects remain opaque unless a concrete provider adapter defines and
proves its semantic invariants.
- Out-of-process plugins exposed to agents as
<plugin>.<tool>. Plugins are
trusted executables, not a security sandbox; calls are policy-gated and do not
start unless their start audit record is durable.
termada update β bounded self-update from GitHub releases on Unix (mandatory SHA-256 verification, optional Ed25519-signed checksums, exact-member extraction, atomic replace). Windows reports an explicit manual-install path because a running .exe cannot be replaced atomically.
Not yet: a native Windows ConPTY runtime (cross-compiles today, but PTY and
signals are stubs) and code-signing / notarization.
Install
One line, no Go needed β downloads a prebuilt macOS or Linux amd64/arm64
binary (SHA-256 verified) to ~/.local/bin:
curl -fsSL https://raw.githubusercontent.com/Islomzoda/termada/main/install.sh | sh
Pin a version with TERMADA_VERSION=vX.Y.Z, or change the location with
TERMADA_BIN_DIR=~/bin. If ~/.local/bin isn't on your PATH, the installer
prints the one line to add.
Other ways β Docker, Homebrew, packages, source
docker run --rm --platform linux/amd64 -p 127.0.0.1:7717:7717 ghcr.io/islomzoda/termada
docker run --rm --platform linux/amd64 -p 127.0.0.1:7717:7717 \
--mount type=volume,src=termada-data,dst=/home/termada/.config/termada \
ghcr.io/islomzoda/termada
brew install Islomzoda/tap/termada
TERMADA_FROM_SOURCE=1 ./install.sh
The Docker command starts the daemon directly; open the tokenized URL printed in
its logs. The native CLI commands below apply when the binary is installed on the
host.
Releases also ship .deb, .rpm, and manual Windows archives on the
releases page. The Windows
binary cross-compiles, but native PTY execution still awaits a ConPTY backend.
Quick start
termada serve
termada dashboard --open
The dashboard bootstrap stores the token in browser session storage and removes
it from the address bar. Static assets are public on loopback, but every TCP
/api/* request and /metrics requires the token. The legacy
dashboard.local_trust setting is deprecated and does not bypass API auth.
Connect it to your agent β this is a one-time, user-wide step. You do it once
per user account and every project gets Termada automatically; there's nothing
to copy into each repo.
For Claude Code, one command does it:
claude mcp add --scope user termada -- termada serve --stdio
Using a different agent (or prefer a file)? Add this once to your global MCP
config β see .mcp.json.example:
{ "mcpServers": { "termada": { "command": "termada", "args": ["serve", "--stdio"] } } }
That's it. From now on, just ask the agent to do terminal work β it flows through
Termada while you watch and control it live. The one shared daemon serves every
project and every agent session, all on the same dashboard.
Configuration is strict: unknown/unsupported fields fail startup. Values written
as ${NAME} are expanded from the environment, and an unset referenced variable
is an error rather than an empty credential. Leave optional credential fields out
until their variables are available.
Reach remote servers through Termada
For the agent to operate a remote box through Termada (observable, reconnecting,
policy-gated) instead of shelling out to raw ssh, register the server once β then
it's reachable by name, no IP and no raw ssh client.
Add it to config.yaml (see config.example.yaml) and
restart the daemon:
servers:
- name: prod
host: prod.example.com
user: deploy
tags: [web]
β¦or add it live from the dashboard (Servers β Add). Confirm it's registered:
Now the agent reaches it by name:
- a remote shell session β
session_create(target="prod"), then run exec_run / exec_start in that session (state persists while connected; after a link drop Termada reconnects a fresh shell, but an orphaned remote process may still be running);
- one command across servers β
fleet_run(command=[...], servers=["prod"]) (or by tag).
- a loopback TCP tunnel β
port_forward(server="prod", remote_host="127.0.0.1", remote_port=5432), then close its returned id with port_forward_close when done.
Make the agent actually use Termada
Agents like Claude Code and Cursor ship with a built-in shell and will reach for it
(and for raw ssh) by default. Two things steer them to Termada:
-
Install the usage skill β the plugin below, or skills/termada. It teaches the agent how to drive the tools (and to route remote work through registered servers instead of ssh).
-
Add a project rule so the agent prefers Termada. Put this in CLAUDE.md
(Claude Code), .cursor/rules (Cursor), or your agent's system prompt:
Use the Termada MCP tools for all shell and remote work β exec_run /
exec_start for commands, session_create(target="<server>") and fleet_run
for remote servers. Do not use the built-in shell or a raw ssh client:
everything must go through Termada so it is observable, reconnecting, and
policy-gated. If a server isn't in server_list(), ask me to register it
rather than falling back to ssh. For a concrete operational outcome,
start with mission_create, use its session for every command, attach real
successful job ids to plan steps, and finish with mission_report.
Install as a Claude Code plugin
This repo is also a Claude Code plugin marketplace β it bundles the MCP server
config and the usage skill (you still need the termada binary on PATH):
/plugin marketplace add Islomzoda/termada
/plugin install termada@termada
Commands are passed as an argv array (["echo", "hi"]), never a shell string,
so metacharacters are literal unless you explicitly invoke a shell such as
["bash", "-lc", "..."]. Explicit shell payloads still pass through policy;
ambiguous compound payloads fail closed when deny/confirm rules are present.

Documentation
Architecture
A single daemon owns runtime state; agents connect through a stdio shim, and
runtime inspection and controlled actions in the dashboard, TUI, and CLI use the
same daemon control plane. Host-owner maintenance commands such as vault-file
creation/reset, installation, service registration, self-update, audit-file
verification, and configuration editing run outside that API and remain part of
the trusted OS/deployment boundary.
