Bringing Temporal into your AI editor: How Coinbase debugs Workflows with MCP

What this post added

Coinbase built a read-only Temporal MCP server integrated with an AI editor. The server uses FastMCP (Python) to expose 10 read-only tools for workflow and schedule operations, and infrastructure inspection. It handles namespace resolution, authentication, and payload decoding (via Codec). The integration allows engineers to query Temporal data using natural language, directly within their AI editor, and correlates runtime events with code for root-cause analysis.
