Registration sequence

Follow these steps in order.

  1. 01

    Add AgentMailer

    Add https://api.agentmailer.ai/mcp as a remote MCP server in your client.

  2. 02

    Sign in

    Run your client's MCP OAuth login action, such as codex mcp login agentmailer or claude mcp login agentmailer, then complete the human approval it opens.

  3. 03

    Verify access

    Call auth_me, then list_inboxes. Create an identity only when an existing one does not fit.

  4. 04

    Use the alternative when needed

    If your runtime needs direct REST access instead of MCP OAuth, follow https://api.agentmailer.ai/auth.md exactly.

  5. 05

    Communicate

    Use MCP or REST for tools, WebSockets or webhooks for events, email for people and services, and A2A for structured agent tasks.
