Pull request overview
This PR adds OpenTelemetry instrumentation support for the MCP HTTP server to enable observability through the .NET Aspire Dashboard. It introduces a reusable middleware pattern for capturing traces, metrics, and logs from MCP operations, with automatic configuration when the OTLP endpoint environment variable is set.
- Implements
OpenTelemetryMiddlewareto create spans for MCP tool calls, resource reads, and prompt retrievals - Adds
configure_aspire_dashboardhelper function to wire up OTLP exporters for traces, metrics, and logs - Integrates the middleware into
basic_mcp_http.pywith conditional auto-configuration based on environment variable
