Unmeasured means there is not enough evidence to decide. How these checks work

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 392 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name ultrapedia.

  • Pass
    Lists tools

    tools/list returned 8 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 392 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 392 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 28 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.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-29T16:08:01.242071Z, within 180 days.

Capabilities

Tools 8

describe

What Ultrapedia holds: the queryable views, every column and what it means, the allowed values of category columns, and how many races there are. Read this before writing SQL for `query`.

Discovered
get_race

Everything about one race: its values, its editions, and for every value the page it was read from and the verbatim quote.

Discovered
propose_correction

Send a value for one field of one race, read from a web page — a correction or a value the index is missing. `field` is a column name from `describe`; `value` is in that column's form and units (gain_m in metres, dates yyyy-mm-dd, start_time HH:MM 24h, price_usd a number). `quote` must be copied verbatim from `source_url` and must show the value. For date, start time, price, aid stations, drop bags and runners, `year` is the edition year. The server checks the quote on the page; the result says whether the value was applied, held for a maintainer, or rejected and why.

Discovered
propose_race

Send a US ultramarathon the index does not have yet. Check with search_races first. `quote` is copied verbatim from `source_url` and names the race. One call for each distance (a 50K and a 100M at the same event are two races).

Discovered
query

Run one read-only SQL SELECT (SQLite) over the views `races`, `editions` and `sources`. Returns columns and rows; `truncated` is true when more rows exist than `limit` (max 500). Example: SELECT slug, name, date, city FROM races WHERE state='CO' AND distance_category='100M' AND date >= date('now') ORDER BY date

Discovered
read_source

Read a public web page the way this server reads it when it checks a quote: its visible text and its links. Use it before `propose_correction` to copy an exact quote, or to read a race page your own tools cannot open. `find` returns only the passages around that text. A value that is a URL (website_url, registration_url) can be shown by a link: quote the sentence that holds it.

Discovered
report_problem

Report something a single value cannot fix: a cancelled or discontinued race, two rows for the same race, a race filed under the wrong distance. Include a source and quote when you have one.

Discovered
search_races

Find races. `text` matches the name, city or start location; `state` is a two-letter code; `distance_category` is one of the values in `describe`; dates are yyyy-mm-dd and filter the current edition's date. Returns the main columns; use `get_race` for everything about one race.
