What is the Agentmail MCP MCP server?

If you want an AI assistant working directly with Agentmail MCP, the agentmail mcp mcp server is the bridge. Use that Streamable HTTP endpoint directly when your client supports remote MCP. It provides the current runtime tool catalog and supports the hosted server's existing OAuth and per-request API-key paths. See the AgentMail MCP documentation.

What Agentmail MCP does

Use that Streamable HTTP endpoint directly when your client supports remote MCP. It provides the current runtime tool catalog and supports the hosted server's existing OAuth and per-request API-key paths. See the AgentMail MCP documentation.

Tools it exposes

Once connected, the assistant can call these 3 tools directly:

  • mcp-manifest.json — generated runtime contract
  • tests — contract and transport checks
  • docs — architecture, compatibility, migration, release, and operations

Installing the agentmail mcp mcp server

The server is distributed via npm as pnpm, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

Before the server will start you need to supply 2 environment variables: AGENTMAIL_API_KEY, YOUR_API_KEY. Keep credentials in your client's env block or a secrets manager rather than committing them.

Where it fits

Knowledge and memory servers address the most frustrating trait of language models — walking into every conversation with no recollection of the last one. Agentmail MCP sits in that group, and the shape of its toolset — mcp-manifest.json, tests, docs — tells you what it is really for. Worth comparing against the other knowledge memory servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This is a hosted server — you point your client at an endpoint rather than running a local process, so there is nothing to keep updated on your machine.
  • It will not start until its required credentials are present, so set those before wondering why the tools never appear.
  • Maintained by agentmail-to, written in Python.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the agentmail mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

Frequently asked questions

It connects Agentmail MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (mcp-manifest.json, tests, docs) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Agentmail MCP directly.
