mcp-observatory-sdk
Tiny SDK that instruments MCP servers with Prometheus metrics + OpenTelemetry spans.
One-line adoption in a FastMCP server:
from fastmcp import FastMCP
from observatory_sdk import instrument
server = FastMCP("my-server")
instrument(server, service_name="my-server", prometheus_port=9090)
# ... register tools as usual ...
Zero runtime deps beyond prometheus-client and opentelemetry-api.
Companion project: mcp-observatory — the query-router MCP server that consumes the metrics this SDK emits.
