Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 442 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name nj-transit.

  • Pass
    Lists tools

    tools/list returned 6 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 442 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 442 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    0 of 13 parameters have a description (0%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass
    Recently updated

Capabilities

Tools 6

lines

All lines/routes. NJ Transit: 17 rail + light-rail routes. NJ bus: 263 routes (short_name is the bus number; long names are empty in the bus feed, use trip headsigns for destinations). PATH: 4 daytime routes.

Discovered
next_departures

Next departures from a station/stop (name or stop ID). system 'nj_transit': rail + light rail, scheduled by default, live delays when NJT credentials are configured. system 'nj_bus': NJ Transit bus, SCHEDULED only in v1.2 (BUSDATA live not enabled). system 'path': live PATH arrivals, no key needed. Times are America/New_York. NOTE: New Jersey Transit has no subway. For a subway-like ride use system='path', or NJ light rail lines HBLR / NLR / River Line.

Discovered
search_stations

Find stations/stops by name. system: 'nj_transit' (rail + light rail), 'nj_bus' (NJ Transit bus street stops), 'path', or 'all'. 'all' includes bus, so a first 'all' search downloads the 50 MB bus GTFS once; use system='nj_bus' for bus-only searches. Returns station/stop IDs to use with next_departures / trip_between.

Discovered
server_status

What data this server is actually serving right now: GTFS date range and counts, whether live NJ data is enabled, PATH feed age. Use this to answer 'is this live or scheduled?' honestly.

Discovered
service_alerts

Service alerts. NJ Transit alerts require NJT credentials (see server_status for how to enable); PATH has no separate alerts feed in v1, so PATH alerts are reported as unavailable, not invented.

Discovered
trip_between

Next NJ Transit trains/buses from origin to destination on the SAME trip (no transfers). Returns departure, arrival and duration. Times ET. system: 'nj_transit' (default, rail + light rail) or 'nj_bus' (bus, scheduled only in v1.2).
