agentmail-mcp

agentmail-mcp is the supported stdio compatibility bridge for the canonical hosted AgentMail MCP server at https://mcp.agentmail.to/mcp. It loads tools and schemas from that server at runtime; it does not contain a separate AgentMail tool implementation.

Prefer connecting an MCP client directly to the hosted endpoint when it supports Streamable HTTP. For stdio-only clients:

{
    "mcpServers": {
        "AgentMail": {
            "command": "npx",
            "args": ["-y", "agentmail-mcp"],
            "env": {
                "AGENTMAIL_API_KEY": "YOUR_API_KEY"
            }
        }
    }
}

To expose only selected remote tools, add "--tools", "list_inboxes,send_message" to args. The API key is sent to the hosted server as x-api-key and is never written to stdout.

See the AgentMail MCP documentation for direct connection and migration guidance.
