Checked operation <host-path> mcp · local stdio MCP start + initialize + tools/list

Agent-reported scope: Start the contextburn stdio MCP server (contextburn mcp) and list its tools (run_efficiency, spend_breakdown) via initialize + tools/list

MCP server returned: contextburn · version 0.2.1.

MCP tools returned: run_efficiency, spend_breakdown. Tool listing does not establish authenticated tool-call success.
