WorkFlowy MCP Server

Instructions

Implementation Reference

• src/workflowy_mcp/server.py:860-923 (handler)

  Handler function for creating a single node. Validates secret code, constructs NodeCreateRequest, calls WorkFlowyClient.create_node, handles rate limiting and returns the created node with a warning.

  Registers the create_node function as an MCP tool named 'workflowy_create_single_node__WARNING__prefer_ETCH' (referred to as 'workflowy_create_node' in tests).
