External Agents
Connect ChatGPT, Claude, Codex, and MCP clients safely.
Connect Claude, ChatGPT, Codex, and other compatible clients to an Agents First workspace through the authenticated MCP control plane.
Before you connect
Use the hosted MCP server URL:
https://app.agentsfirst.ai/api/external-agent/mcp
This is the workspace control plane. It requires OAuth 2.1 authorization and never uses the retired marketing MCP endpoint.
Choose your client
- CLI-first connect quickstart — live copy-paste commands (Claude Code, Codex +
config.toml, Claude web/Desktop, ChatGPT). - MCP setup explains the connector URL and client-specific steps (same snippets; points at the canonical connect page).
- OAuth and auth.md explains discovery, registration, authorization, and revocation.
- OpenAPI describes the public REST specification and its relationship to authenticated APIs.
What happens during connection
Your client discovers the protected resource metadata, opens the Agents First authorization flow, and asks a workspace or agency operator to approve the requested access. The resulting token is scoped to that grant and can be revoked from the access portal.
