Starlark MCP runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 8 Nov 2026.
Starlark MCP: 20 real tools to read, check, lint, scaffold, build and run Starlark code.
Today is the operative word: we check Starlark MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
