exact-match lookup + slug audit — artlu-tracker-mcp
Audited all 58 tracker projects and patched a day-1 substring-match bug in the MCP that had been silently picking the wrong project when a name was a substring of others.
What shipped
Two things, one cleanup pass.
The audit. Ran a sweep across all 58 projects in the artlu.ai tracker. 14 had no slug field at all — the auto-slug helper was added in April but never backfilled the older entries. 3 more had stale slugs that no longer matched their names, including one whose slug still said "control-surface" because the project had been renamed to "dashboard" months ago and the slug never followed. Fixed all 17 via the MCP's update_project tool.
The bug it exposed. Got to a project literally named artlu.ai and the MCP confidently updated a different one — the homepage-showcase project whose name ends with — artlu.ai. The response text named the wrong project, which is how we caught it. Reverted, dug in.
Root cause: get_project and update_project both used pure substring match — name.toLowerCase().includes(query.toLowerCase()). Nine projects in the tracker contain artlu.ai as a substring (— artlu.ai, — artlu.ai v2, etc). The matcher returned the first hit in Firestore document-id order. The doc id of the real artlu.ai project is mE3rAaf8IZqxEn4t3Rj4. Homepage-showcase is 4EdEwKBbJWejkxwv8WVw. 4 < m alphabetically — homepage-showcase always won.
Couldn't even use the MCP to verify the real artlu.ai's slug (same collision). Wrote a 6-line Node script using Firebase Admin to read the doc by id directly, just to confirm it already had the right slug.
The fix. Added a findProjectDoc() helper — first tries exact (case-insensitive) name match, falls back to substring if no exact hit. Patched both tools. ~10 lines of code. npm run build, restart Claude, verify. get_project("artlu.ai") now returns the real project.
The meta beat. The bug had been in the MCP since day 1. Never bit me until today. It took a project whose entire name was a substring of several others to trigger.
Also updated artlu-tracker-mcp/README.md tools table and the cross-project artlu-knowledge-base/context.md with the fix notes alongside the existing slug auto-gen entry.
