Cursor Posthog resolution_diff

How to: Cursor Posthog resolution_diff

client:Cursor transport:streamable-http tool:resolution_diff

Add Posthog to Cursor

  1. 01

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

{
  "mcpServers": {
    "posthog": {
      "url": "https://gateway.pipeworx.io/posthog/mcp"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Posthog'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

Set these first

Posthog will not start until these are set, so resolution_diff never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 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.
