GTFS Feed Check questions
Scope and boundaries for GTFS Feed Check.
01What does GTFS Feed Check actually check?
Validate one public GTFS Schedule feed against the GTFS specification and Best Practices with exact notice-code and file-location evidence, or compare two feeds before and after a schedule change, with a clear automated-versus-human-review boundary.
02What does it never do?
It reports what its pinned engine measured and nothing more — it does not judge quality, correctness of your underlying business decisions, or anything outside its stated scope, and it never fabricates a result.
03What does it cost?
Nothing. Every published app is free to use with fair-use rate limits.
04Can my assistant connect directly?
Yes — any MCP-compatible assistant can connect straight to the canonical endpoint: https://powmcp.com/gtfs-feed-check/mcp. Marketplace listings are conveniences over the same live engine.
