Innmail MCP

An official MCP server provided by Innmail that allows AI agents to manage email inboxes. It enables reading threads, sending and replying to emails, scheduling drafts, extracting verification codes, and managing a calendar, all while supporting human approval for risky sends.

Endpoint and access

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http innmail-mcp https://www.innmail.app/api/v1/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 innmail-mcp --url https://www.innmail.app/api/v1/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable innmail-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "innmail-mcp": {
      "url": "https://www.innmail.app/api/v1/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "innmail-mcp": {
      "type": "streamableHttp",
      "url": "https://www.innmail.app/api/v1/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start innmail-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "innmail-mcp": {
      "type": "http",
      "url": "https://www.innmail.app/api/v1/mcp"
    }

Gemini CLI configuration
gemini mcp add --transport http innmail-mcp https://www.innmail.app/api/v1/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
