Mailows MCP

The Mailows MCP server enables AI agents to manage email inboxes via scoped, revocable OAuth grants. It allows agents to list messages, read content, and send emails with attachments using Streamable HTTP transport, ensuring secure access without exposing human mail or requiring static API keys.

Endpoint and access

OAuth sign-in: the first time you connect, your client opens the vendor's own authorization prompt in a browser.

What you can do with it

  • List messages in agent mailboxes
  • Read email content securely
  • Send text, HTML, and attachments
  • Manage OAuth consent and revocation

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http mailows-mcp https://mcp.mailows.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add mailows-mcp --url https://mcp.mailows.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable mailows-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "mailows-mcp": {
      "url": "https://mcp.mailows.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
Cline configuration
{
  "mcpServers": {
    "mailows-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.mailows.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start mailows-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "mailows-mcp": {
      "type": "http",
      "url": "https://mcp.mailows.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http mailows-mcp https://mcp.mailows.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "mailows-mcp": {
      "url": "https://mcp.mailows.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "mailows-mcp": {
      "serverUrl": "https://mcp.mailows.com/mcp"
    }
  }
}

Ground your agent in cited data

Mailows MCP gives your agent tools. Koskamo gives it reviewed, cited facts to check its answers against. Add it as a second MCP server; public reads need no API key.
