Implementation Reference

• src/mcp_agile_flow/fastmcp_tools.py:53-117 (handler)

  The primary MCP tool handler decorated with @mcp.tool(). Handles input validation, safety checks (e.g., rejects root path), calls the utility function get_settings_util, formats the response as JSON with success flag, and handles exceptions.

  Core utility function implementing the logic to determine project path (from env, proposed, cwd), detect project type based on IDE rule directories, create/get special directories (ai-docs, .ai-templates), and compile settings dictionary.
