Sourcemap Retrace MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 36 installs a week from npm. Last commit 20 May 2026.
Decodes minified production stack traces back to original TypeScript source using source maps.
Today is the operative word: we check Sourcemap Retrace MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
