Overview

AI-generated overview

A remote MCP server for a cited index of US ultramarathons, letting an assistant search races, run read-only SQL, and propose sourced corrections.

What you can do
  • Search and look up races by name, place, distance and date, or fetch one race with its editions and the source page and quote behind every value
  • Run read-only SQL SELECT queries over the races, editions and sources views, and inspect the schema and allowed values
  • Read a public web page as visible text and links, optionally narrowed to passages around a search term
  • Submit a sourced correction for one field, propose a missing race, or report a problem such as a cancelled race or duplicate
When to use it
Useful when an assistant needs structured, source-backed facts about US ultramarathon dates, locations, distances, elevation, prices and logistics, and when it should be able to feed verified corrections back into the index.
Requirements
A remote streamable HTTP endpoint; no package, environment variable or header is declared. The server fetches cited web pages itself, so it needs network access on its side.
Before you install
The propose_correction, propose_race and report_problem tools send data to the index and can change it; the server fetches each cited page and checks the quote before applying anything. Contribute only values read on a page, never guesses. The read_source tool fetches arbitrary public pages on the server's behalf.

Installation

In SourceWeft

  1. Open Ultrapedia in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/run.ultrapedia%2Fultrapedia/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

describe

Describe the data

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`.

Takes no parameters.

query

Run a SQL 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

Parameterssqlrequiredlimit

search_races

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.

Parameterstextlimitstatedate_todate_fromdistance_category

get_race

Get a race with sources

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

Parametersslugrequired

read_source

Read a source page

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.

Parametersurlrequiredfind

propose_correction

Propose a 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.

Parametersslugrequiredyearfieldrequiredquoterequiredvaluerequiredsource_urlrequired

propose_race

Propose a new 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).

Parameterscitynamerequiredquoterequiredstatesource_urlrequiredwebsite_urldistance_categoryrequired

report_problem

Report a 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.
