8a13032419* Use standard traceparent/tracestate keys per OTel MCP semconv The OTel semantic conventions for MCP (https://opentelemetry.io/docs/specs/semconv/gen-ai/mcp/) put `traceparent` and `tracestate` directly in `params._meta` without a prefix. FastMCP was using `fastmcp.traceparent` / `fastmcp.tracestate`, which meant non-FastMCP clients sending the standard keys couldn't propagate traces. Switches injection to the bare keys and adds fallback extraction for the old prefixed keys so older FastMCP clients still work. 🤖 Generated with Claude Code Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: Update SDK documentation * Drop legacy fastmcp.-prefixed trace key fallback 🤖 Generated with Claude Code Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: Update SDK documentation --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: marvin-context-protocol[bot] <225465937+marvin-context-protocol[bot]@users.noreply.github.com> |
