"type": "http",
"url": "https://paperagent.dev/mcp"
}
}

Save the file and restart VS Code.

If nothing happens, check the server is running and that PaperAgent — Send Physical Mail's identifier in your config matches the one above exactly.

This list was read from the server itself, by connecting to it and calling tools/list on 18 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.
