Cost Guard MCP runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 17 Sep 2026.
Pre-flight query cost and result-size guardrails for AI agents on BigQuery, Snowflake, Databricks
Today is the operative word: we check Cost Guard MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
