Debugging Agent Traces with the Logfire MCP Server
samuelcolvin · x · 2026-08-18
Introduces the use cases of the Pydantic Logfire MCP server and an upcoming technical session:
- Pain Point: When an agent behaves strangely, the answer is often buried in thousands of spans, making debugging hard.
- Solution: Use the Logfire MCP server to query OpenTelemetry traces, chart them, and ask follow-up questions directly from your editor, terminal, or coding agent.
- Value: Supports tracing requests across model calls, APIs, and databases; allows turning one-off investigations into saved dashboards, alerts, or SLOs.
Pydantic will host a 45-minute live demo showing how to go from a vague question to a root cause.
