Mailopoly MCP MCP server

Mailopoly MCP allows AI assistants to connect to a unified inbox, enabling users to search across multiple email accounts (Gmail, Outlook, iCloud, Yahoo, IMAP) and business channels (Slack, Teams, WhatsApp, etc.) from a single connection. It supports searching by sender, date, or topic, summarizing non-promotional feeds, tracking bills and deliveries, managing tasks, and replying from the appropriate account or channel.

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 mailopoly-mcp https://fastapi.prod.aws.mailopoly.com/mcp-server

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 mailopoly-mcp --url https://fastapi.prod.aws.mailopoly.com/mcp-server

Cursor

Merge this server into .cursor/mcp.json in your project, then enable mailopoly-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "mailopoly-mcp": {
      "url": "https://fastapi.prod.aws.mailopoly.com/mcp-server"
    }
  }
}

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": {
    "mailopoly-mcp": {
      "type": "streamableHttp",
      "url": "https://fastapi.prod.aws.mailopoly.com/mcp-server",
      "disabled": false
