Developed and delivered the serverExecutionTelemetry capability for the ArcadeAI/arcade-ai repository, enabling cross-organization distributed tracing by returning server-side OpenTelemetry spans directly to clients. This work introduced TelemetryPassbackMiddleware and ContextVarSpanCollector in Python to capture and propagate execution traces during server operations, leveraging API development and distributed tracing expertise. The client-side integration allowed agents to detect tracing capabilities, propagate traceparent headers, and ingest server spans into OTLP collectors such as Jaeger and Galileo. The implementation enhanced observability by surfacing server execution details to clients, and included dependency updates and versioning to support the new tracing features without requiring shared infrastructure.
Monthly summary for 2026-03: ArcadeAI/arcade-ai delivered serverExecutionTelemetry to enable cross-organization distributed tracing, enhancing observability by surfacing server-side execution spans directly to clients. The work includes server-side TelemetryPassbackMiddleware, per-request span collection via ContextVarSpanCollector, and traceparent propagation to stitch distributed traces without shared infrastructure. Client-side reference agent detects the capability, dynamically wraps MCP tools for trace propagation, and ingests returned OTLP spans into Jaeger/Galileo pipelines. A two-act demo illustrated default full server-visibility vs. no-passback modes. Dependencies updated (opentelemetry-api/sdk) and arcade-mcp-server version bumped to 1.18.0 (SEP-2448/PR #2448).
