tabellum-mcp

The stdio shim for Tabellum's MCP server. The Tabellum desktop app hosts an MCP server on loopback while it runs; this package forwards MCP clients that only speak stdio (Claude Code, Cursor, …) to it. It has no tools of its own — the tool list, the approval gate, and the privacy rules are the app's.

// Claude Code: .mcp.json
{
  "mcpServers": {
    "tabellum": {
      "command": "npx",
      "args": ["-y", "@dudko.dev/tabellum-mcp"]
    }
  }
}

The shim reads the app's discovery file, ~/.tabellum/mcp.json, for the port and the per-install token. If the app is not running, every call answers "Tabellum is not running" instead of starting anything.

Requires Node.js 24 or newer. Desktop only: the app hosts the server on macOS, Windows, and Linux.

What an agent gets

The same tools as the in-app agent: list_connections, describe_schema, describe_object, sample_rows, run_read, propose_write, explain, draft_to_editor, plus open_editor_tab. Reads run at once; anything else waits for the user's click in the app. Row data crosses the boundary only when the connection shares it.
