Mission Control Backend (FastAPI)

This directory contains the Mission Control backend API (FastAPI + SQLModel) and its database migrations (Alembic).

• Default API base URL: http://localhost:8000
• Health endpoints: /healthz, /readyz
• API routes: /api/v1/*

Requirements

• Python 3.12+
• uv (recommended; used by this repo)
• Postgres (local or Docker)

Quick start (local backend + Docker Postgres)

From the repo root:

# start dependencies
cp .env.example .env
docker compose -f compose.yml --env-file .env up -d db

# run backend
cd backend
cp .env.example .env

uv sync --extra dev
uv run uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

Verify:

curl -f http://localhost:8000/healthz

Configuration / environment variables

Backend settings are defined in app/core/config.py via pydantic-settings.

The backend loads env files in this order:

1. backend/.env (preferred)
2. .env (current working directory)

A starter file exists at backend/.env.example.

Core

• ENVIRONMENT (default: dev)
  • In dev, if you don’t explicitly set DB_AUTO_MIGRATE, the backend defaults it to true.
• LOG_LEVEL (default: INFO)
• DATABASE_URL
  • Default: postgresql+psycopg://postgres:postgres@localhost:5432/openclaw_agency
  • Recommended local/dev default (matches backend/.env.example): postgresql+psycopg://postgres:postgres@localhost:5432/mission_control
• CORS_ORIGINS (comma-separated)
  • Example: http://localhost:3000
• BASE_URL (required for gateway provisioning/agent heartbeat templates; no fallback)

Database lifecycle

• DB_AUTO_MIGRATE
  • If true: on startup, the backend attempts to run Alembic migrations (alembic upgrade head).
  • If there are no Alembic revision files yet, it falls back to SQLModel.metadata.create_all.

Forgejo scheduled sync

• FORGEJO_SYNC_ENABLED (default: true)
  • When enabled, the API seeds a periodic Forgejo issue-cache sync task into the RQ queue on startup.
• FORGEJO_SYNC_INTERVAL_SECONDS (default: 3600)
  • How often the worker syncs all active Forgejo repositories.
• FORGEJO_SYNC_STARTUP_DELAY_SECONDS (default: 60)
  • Initial delay before the first scheduled sync after API startup.

Security headers

Security response headers added to every API response. Set any variable to blank to disable the corresponding header.

• SECURITY_HEADER_X_CONTENT_TYPE_OPTIONS (default: nosniff)
• SECURITY_HEADER_X_FRAME_OPTIONS (default: DENY)
• SECURITY_HEADER_REFERRER_POLICY (default: strict-origin-when-cross-origin)
• SECURITY_HEADER_PERMISSIONS_POLICY (default: blank — disabled)

Auth (Clerk)

Clerk is used for user authentication (optional for local/self-host in many setups).

• CLERK_SECRET_KEY (required)
  • Used to fetch user profile fields (email/name) from Clerk when JWT claims are minimal.
• CLERK_API_URL (default: https://api.clerk.com)
• CLERK_VERIFY_IAT (default: true)
• CLERK_LEEWAY (default: 10.0)

Database migrations (Alembic)

Migrations live in backend/migrations/versions/*.

Common commands:

cd backend

# apply migrations
uv run alembic upgrade head

# create a new migration (example)
uv run alembic revision --autogenerate -m "add foo"

Notes:

• The backend can also auto-run migrations on startup when DB_AUTO_MIGRATE=true.
• The database URL is normalized so postgresql://... becomes postgresql+psycopg://....

Running tests / lint / typecheck

From repo root (recommended):

make backend-lint
make backend-test
make backend-coverage

make backend-lint runs backend format checks (isort, black), lint (flake8), and typecheck (mypy) in one command.

Or from backend/:

cd backend
uv run pytest
uv run isort . --check-only --diff
uv run black . --check --diff
uv run flake8 --config .flake8
uv run mypy

Formatting:

make backend-format
make backend-format-check

Scripts

Backend scripts live in backend/scripts/:

• export_openapi.py – export OpenAPI schema
• seed_demo.py – seed demo data (if applicable)
• sync_gateway_templates.py – sync repo templates to an existing gateway

Run with:

cd backend
uv run python scripts/export_openapi.py

Troubleshooting

Backend can’t connect to Postgres

• If you started Postgres via compose, make sure it is healthy:

  docker compose -f compose.yml --env-file .env ps
  docker compose -f compose.yml --env-file .env logs -f --tail=200 db
  

• If backend runs locally (not in compose), DATABASE_URL should usually point at localhost.

CORS issues from the frontend

• Set CORS_ORIGINS=http://localhost:3000 (or a comma-separated list) in backend/.env.
• Restart the backend after changing env vars.

Alembic / migrations not applying

• If you want deterministic behavior, run migrations manually:

  cd backend
  uv run alembic upgrade head
  

• If DB_AUTO_MIGRATE=false, the backend may use create_all instead of Alembic.
