Tools

analyze_gtfs_file

ChatGPT

Use for an attached/uploaded GTFS Schedule ZIP when the user asks to validate or analyze it, check publishability, or find GTFS issues. This includes /gtfs plus a ZIP and requests such as Bu GTFS dosyasını analiz et. The file must be passed through the ChatGPT file handoff. Returns the GTFS Analyzer engine's publishability, scores, severity counts, feed metrics, and prioritized findings without recalculating them in MCP.

analyze_gtfs_url

ChatGPT

Use for a public, directly downloadable GTFS Schedule ZIP URL when the user asks to validate or analyze it, check publishability, or find GTFS issues. This includes /gtfs followed by a URL. Only public HTTP/HTTPS URLs are accepted; uploaded files belong to analyze_gtfs_file. Returns the GTFS Analyzer engine's result without recomputing it in MCP.

get_gtfs_rule

ChatGPT

Use when the user asks what a GTFS Analyzer rule means or provides a rule code, including /gtfs TRP_002. Returns the canonical Analyzer metadata for that rule ID; do not infer or rewrite rule details.
