MCP server for profiling and analyzing distributed traces from LLM applications using OpenTelemetry, identifying bottlenecks and exporting trace data
This server has critical definition failures. The single tool 'execute_skill_action' has no visible input schema, no parameter descriptions, and a generic 1-line description (18 chars, below the 20-char minimum). The mcp_server.py file does not implement the MCP protocol, it merely prints a JSON status message and exits. There is no tool registration, no schema validation, no parameter handling, and no actual MCP server loop. The tool definition is inferred from example_usage.py, not explicitly registered. This is not a functional MCP server.
Execute distributed trace profiling and analysis skill action
No input schema visible for execute_skill_action. Tool accepts parameters (trace_id, spans_list) but no JSON Schema definition exists in the code.
Tool description is 18 characters ('Execute distributed trace profiling and analysis skill action'), below 20-char minimum. Description lacks WHAT, WHEN, and prerequisites.
No parameter descriptions. 'trace_id' and 'spans_list' parameters have no documentation explaining format, constraints, or purpose. LLMs cannot infer parameter meaning from names alone.
Tool definition is inferred from example_usage.py, not explicitly registered in mcp_server.py. This server does not implement MCP tool registration.

No output schema documented. The client.profile_trace() method returns a dict with fields (total_duration_ms, bottleneck_span, otel_export_status), but no schema is declared for the tool response. LLMs cannot plan downstream calls without knowing output structure.
