Cursor WhiteMagic — governed local memory for agent continuity session.checkpoint

How to: Cursor WhiteMagic — governed local memory for agent continuity session.checkpoint

client:Cursor transport:streamable-http tool:session.checkpoint

Add WhiteMagic — governed local memory for agent continuity to Cursor

  1. 01

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

{
  "mcpServers": {
    "whitemagic-mcp": {
      "url": "https://mcp.whitemagic.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that WhiteMagic — governed local memory for agent continuity'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 24 September 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.
