Data Baltimore is answering right now. Last checked 4 min ago. It exposes 34 tools. Last commit 18 Sep 2026.
DataBaltimore MCP — Baltimore open data (data.baltimorecity.gov, ArcGIS REST API).
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 8 August 2026. No other catalogue keeps this.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 4 min ago.
