Connect Sendy 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.

Sendy MCP Config for Cursor

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

  "mcpServers": {
    "kosmokrator-sendy": {

      "args": [
        "mcp:serve",
        "--integration=sendy",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually

Why Use KosmoKrator Here
