agent-control-server 8.3.0

Server for Agent Control - manage and evaluate controls for AI agents

Agent Control Server

FastAPI server that powers Agent Control. It manages agents and controls, evaluates requests at runtime, and exposes REST APIs used by the SDKs and UI.

What it provides

• Agent registration and control association
• Control CRUD and evaluator configuration
• Runtime evaluation (/api/v1/evaluation) with pre/post stages
• Observability endpoints for events and stats
• API key authentication for production deployments

Quick start (local)

From the repo root:

make sync
make server-run

Server runs on http://localhost:8000. The UI expects this base URL by default.

To use non-default local ports with make server-run, export AGENT_CONTROL_PORT for the server listen port. If you also want the local Postgres container exposed on a different host port, set AGENT_CONTROL_DB_HOST_PORT and point the server at the same value with AGENT_CONTROL_DB_PORT.

Database migrations

The server package includes the agent-control-migrate command for bundled Alembic migrations.

In production, migrations are serialized with a Postgres advisory lock. Alembic runs each migration revision in its own transaction, so if an upgrade across multiple revisions fails, earlier revisions may already be committed. Check the current revision before retrying:

agent-control-migrate current
agent-control-migrate upgrade head

PostgreSQL driver runtime

agent-control-server depends on plain psycopg. The published Docker image installs Debian libpq5 and sets PSYCOPG_IMPL=python so the server uses psycopg's Python implementation with the OS libpq library.

For wheel-based deployments outside Docker, either install the OS libpq runtime package for your platform, or install agent-control-server[binary] if you want psycopg's bundled binary package.

Configuration

Server configuration is driven by environment variables (database, auth, observability, evaluators). For the full list and examples, see the docs.
