Build an MCP Server Observability & Governance Workflow with LangGraph
SnapLogic's August 13, 2026 release elevated MCP from a feature into infrastructure: a dedicated MCP Metrics page now tracks traffic, error rates, tool calls, and P99 latency across every deployed server, and a token-exchange rule implements RFC 8693 so inbound agent tokens swap for narrowly scoped downstream credentials. This workflow builds the same operational layer with LangGraph — an observability pipeline that ingests MCP server telemetry, detects degradation before users do, and enforces scoped-credential exchange on every agent tool call.
