How to: Cursor WarmInboxes Free Deliverability Tools segment_esp

client:Cursor transport:streamable-http tool:segment_esp

Add WarmInboxes Free Deliverability Tools to Cursor

  1. 01

    Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "deliverability-tools": {
      "url": "https://warminboxes.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

    Ask for something segment_esp does. Cursor lists the server's tools on connect and calls segment_esp itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that WarmInboxes Free Deliverability Tools's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 22 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
