Category Maps and Location
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security50
- Malware scan not yet available for this package.Unverified
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 16 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to ChelseaKR/gtfs-scorecard). View diagnostics → Pass
- Clear OSI-approved license (Apache-2.0).Pass
- Actively maintained (last published 7 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 744 tokens (~82/item across 9 items; 9 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
coverage_for ~92
Covered-set totals for one ISO country, or one subdivision inside it. A place this scorecard does not track is reported as not covered rather than as zero feeds: absence of coverage is not absence of transit data.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | yes | ISO 3166-1 alpha-2 country code, e.g. US |
| subdivision | string | – | Optional ISO 3166-2 code or subdivision name |
No output schema declared.
No examples provided.
coverage_stats ~27
Coverage-wide quality totals and portable country/subdivision rollups over the feeds this scorecard tracks.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
explain_finding ~108
The fix recipe for one validator or scorecard notice code, its authoritative rule link, and, when a producing tool is named, that tool's fix path. A code with no written recipe returns the rule link alone and says so; nothing is described beyond what is written.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | Notice code, e.g. 'expired_calendar' |
| tool | string | – | Optional producing-tool key: trillium, gtfs_builder, remix, passio, repo, or archive |
No output schema declared.
No examples provided.
get_evidence_packet ~61
The deterministic vendor remediation packet for one agency's latest scorecard: the producer contract, the work items with their acceptance tests, and the feed identity they were measured against.
| Name | Type | Req | Description |
|---|---|---|---|
| agency_id | string | yes | Agency slug, e.g. 'unitrans' |
No output schema declared.
No examples provided.
get_history ~138
One feed's dated grade and score history, with every measurement-contract boundary marked. A point marked comparable_with_previous: false was scored under a different rubric, scoring profile, validator, reader archive profile, or measured-category set, and the difference across it is not a change in the feed. Also reports findings that appeared or cleared between the two most recent snapshots, but only when those two are comparable.
| Name | Type | Req | Description |
|---|---|---|---|
| agency_id | string | yes | Agency slug, e.g. 'unitrans' |
| limit | integer | – | Max dated points (default and ceiling 120) |
| since | string | – | Earliest snapshot date to include, YYYY-MM-DD |
No output schema declared.
No examples provided.
get_rollup ~64
One program rollup: the cohort's shared fixes, grade distribution, and the members needing attention. Shared fixes describe work many feeds share; they are not a ranking of agencies.
| Name | Type | Req | Description |
|---|---|---|---|
| rollup_id | string | yes | Rollup id, e.g. 'california' |
No output schema declared.
No examples provided.
get_scorecard ~61
An agency's latest scorecard: overall grade, category scores and plain-language summaries, every finding with its fix and effort, top fixes, and NTD GTFS readiness.
| Name | Type | Req | Description |
|---|---|---|---|
| agency_id | string | yes | Agency slug, e.g. 'unitrans' |
No output schema declared.
No examples provided.
national_stats ~42
Legacy United States policy view: NTD GTFS readiness nationally and by state, plus the backwards-compatible covered-corpus stats member. Prefer coverage_stats for geography-neutral totals.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_agencies ~151
Search tracked transit agencies by name, id, ISO country, ISO subdivision or subdivision name, legacy state, or letter grade. Returns portable location, grade, score, expiry, and applicable readiness fields.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | ISO 3166-1 alpha-2 country code, e.g. CA |
| grade | string | – | Letter grade A-F |
| limit | integer | – | Max results (default 20) |
| query | string | – | Name fragment or exact agency id |
| state | string | – | Legacy state/province-name filter; prefer subdivision |
| subdivision | string | – | ISO 3166-2 code or subdivision name, e.g. CA-ON or Ontario |
No output schema declared.
No examples provided.

What is the GTFS Scorecard MCP server?
GTFS Scorecard is an MCP server listed in the public MCP registry as io.github.ChelseaKR/gtfs-scorecard. Read-only GTFS transit feed scorecards: grades, plain-language fixes, and history. This page covers its PyPI package (gtfs-scorecard).
Is the GTFS Scorecard MCP server safe to use?
GTFS Scorecard scores 65 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 19 October 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the GTFS Scorecard MCP server expose?
GTFS Scorecard exposes 9 tools: search_agencies, get_scorecard, national_stats, coverage_stats, get_history, and 4 more. Their descriptions and schemas cost roughly 744 tokens of context every time the server is loaded.
Is the GTFS Scorecard MCP server still maintained?
GTFS Scorecard is still listed as active in the MCP registry. We last reached this channel on 19 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the GTFS Scorecard MCP server under?
GTFS Scorecard declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
