Connect Xero to Cursor

Expose selected local integrations to Cursor through KosmoKrator without configuring each service as its own MCP server.

Create or update .cursor/mcp.json with a KosmoKrator stdio server entry. The gateway is local, scoped to this integration, and starts with --write=deny so Cursor can inspect read-capable tools without receiving write access by default.

Xero MCP Config for Cursor

Use the same KosmoKrator install and integration credentials that power terminal and headless runs.

{
  "mcpServers": {
    "kosmokrator-xero": {
      "type": "stdio",
      "command": "kosmo",
      "args": [
        "mcp:serve",
        "--integration=xero",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually

kosmokrator mcp:serve --integration=xero --write=deny

Why Use KosmoKrator Here

Scoped tools

Expose only Xero instead of a broad multi-service tool list.

Local credentials

Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.

Write policy

Start read-only, then opt into ask or allow for trusted workspaces.
