This module provides native OpenTelemetry integration for FastMCP servers and clients. It uses only the opentelemetry-api package, so telemetry is a no-op unless the user installs an OpenTelemetry SDK and configures exporters. Example usage with SDK: ```python from opentelemetry import trace from opentelemetry.sdk.trace import TracerProvider from opentelemetry.sdk.trace.export import ConsoleSpanExporter, SimpleSpanProcessor # Configure the SDK (user responsibility) provider = TracerProvider() provider.add_span_processor(SimpleSpanProcessor(ConsoleSpanExporter())) trace.set_tracer_provider(provider) # Now FastMCP will emit traces from fastmcp import FastMCP mcp = FastMCP("my-server") ``` )Any)context) propagatetrace)Context)SpanStatus StatusCodeTracer) get_tracerfastmcp traceparent tracestateNc>V^8dQhR\R,R\/#)versionNreturn)strr )formats"W/Users/agent/.openclaw/workspace/venv/lib/python3.14/site-packages/fastmcp/telemetry.py __annotate__r&s : :d :f :c"\\V4#)zGet the FastMCP tracer for creating spans.
