MCP Search Server

# MCP Agent example ```bash uv run tracing/agent ``` This example shows tracing integration in a basic "finder" Agent which has access to the 'fetch' and 'filesystem' MCP servers. The tracing implementation will log spans to the console for all agent methods. ### Exporting to Collector If desired, [install Jaeger locally](https://www.jaegertracing.io/docs/2.5/getting-started/) and then update the `mcp_agent.config.yaml` for this example to have `otel.otlp_settings.endpoint` point to the collector endpoint (e.g. `http://localhost:4318/v1/traces` is the default for Jaeger via HTTP). <img width="2160" alt="Image" src="https://github.com/user-attachments/assets/93ffc4e5-f255-43a9-be3a-755994fec809" />
