WorkFlowy MCP Server

Instructions

Implementation Reference

• src/workflowy_mcp/server.py:194-227 (handler)

  MCP tool handler and registration for workflowy_list_nodes. Handles input validation from function signature, rate limiting, calls WorkFlowyClient.list_nodes, and formats response.

• src/workflowy_mcp/models/requests.py:52-56 (schema)

  Pydantic input schema model NodeListRequest used to construct the API request payload.

• src/workflowy_mcp/client/api_client.py:143-167 (helper)

  Core helper method in WorkFlowyClient that executes the HTTP GET request to /nodes, parses the response into WorkFlowyNode objects, and handles errors.
