AgentAPI

AgentAPI

AgentAPI is deprecated and no longer maintained. We recommend using Coder Agents for Coder's own agent harness, or the modules in the Coder Registry that no longer use AgentAPI.

Control Claude Code, AmazonQ, Opencode, Goose, Aider, Gemini, GitHub Copilot, Sourcegraph Amp, Codex, Auggie, and Cursor CLI with an HTTP API.

You can use AgentAPI:

- to build a unified chat interface for coding agents
- as a backend in an MCP server that lets one agent control another coding agent
- to create a tool that submits pull request reviews to an agent
- and much more!

Quickstart

1. Install agentapi:

   Alternatively, you can download the latest release binary from the releases page.

1. Verify the installation:
On macOS, if you're prompted that the system was unable to verify the binary, go to System Settings -> Privacy & Security, click "Open Anyway", and run the command again.

1. Run a Claude Code server (assumes claude is installed on your system and in the PATH):
If you're getting an error that claude is not in the PATH but you can run it from your shell, try which claude to get the full path and use that instead.

1. Send a message to the agent:

1. Get the conversation history:

1. Try the chat web interface at http://localhost:3284/chat.

CLI Commands

agentapi server

Run an HTTP server that lets you control an agent. If you'd like to start an agent with additional arguments, pass the full agent command after the -- flag.

You may also use agentapi to run the Aider and Goose agents:

When using Claude, Codex, Opencode, Copilot, Gemini, Amp or CursorCLI, always specify the agent type explicitly (eg: agentapi server --type=codex -- codex), or message formatting may break.

An OpenAPI schema is available in openapi.json.

By default, the server runs on port…
