Connect Google Tasks to LangChain

Bridge LangChain agents to local KosmoKrator integration tools through MCP or headless CLI calls.

Use the MCP gateway when the agent should discover tools, or wrap kosmo integrations:call for fixed chains. The gateway is local, scoped to this integration, and starts with --write=deny so LangChain can inspect read-capable tools without receiving write access by default.

Google Tasks MCP Config for LangChain

Keep the gateway scoped to the integration and operation class needed by the chain.

{
  "mcpServers": {
    "kosmokrator-google_tasks": {
      "type": "stdio",
      "command": "kosmo",
      "args": [

        "--integration=google_tasks",

      ]
    }
  }
}

Run the Gateway Manually

Why Use KosmoKrator Here

Scoped tools

Expose only Google Tasks 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.
