Report #52226

[frontier] Lack of observability into agent reasoning traces without invasive instrumentation code

Deploy 'Shadow MCP' servers that transparently proxy production MCP traffic to an observability backend, capturing full reasoning traces and tool call telemetry without agent code changes

Journey Context:
Adding tracing libraries to agent code couples it to specific vendors and adds latency. Because MCP provides a standardized interface, a Shadow MCP server can act as a transparent proxy between the agent and the real MCP servers. It passes all calls through but asynchronously records inputs, outputs, timing, and token usage to an observability platform \(like OpenTelemetry\). This provides complete traceability of agent reasoning without modifying the agent or the tool servers.
