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.
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.
Once connected, the assistant can call these 3 tools directly:
mcp-manifest.json — generated runtime contracttests — contract and transport checksdocs — architecture, compatibility, migration, release, and operationsThe 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.
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.
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.
| Tool | What it does |
|---|---|
