Public documentation

OpenAPI

REST API discovery for external tools.

The public Agents First REST specification is available at:

https://agentsfirst.ai/api/openapi.json

Use the public OpenAPI document for public REST discovery. Workspace and agency operations require OAuth and are exposed through the authenticated Agents First control plane.

Authenticated external-agent OpenAPI (grant required) documents tool call responses including policy deny (422 application/problem+json) and defer (202 + Retry-After, no Location). See Result contracts.

MCP for workspace operations

For Claude, ChatGPT, Codex, and compatible MCP clients, connect to:

https://app.agentsfirst.ai/api/external-agent/mcp

The MCP endpoint publishes its protected-resource metadata at:

https://app.agentsfirst.ai/.well-known/oauth-protected-resource/api/external-agent/mcp

See MCP setup for client-specific connection steps and OAuth and auth.md for the authorization lifecycle.
