Data MCP Server

Official TheRundown Data MCP

This is the official TheRundown source repository. aigeon-ai/therundown is unofficial.

A local, read-only Model Context Protocol server for TheRundown Product API. It fetches sports, affiliates, market definitions, events, futures, and open main lines using your own API key. It uses the official MCP SDK and Node.js 22+.

This directory is a runnable source example. The same six tools are also deployed as a hosted, authenticated Streamable HTTP endpoint at https://mcp.therundown.io/mcp; there is still no published npm package. The existing https://docs.therundown.io/mcp endpoint searches documentation only.

Cursor configuration for that server is in the Documentation MCP repository.

The separate HTTP adapter implements the hosted endpoint at https://mcp.therundown.io/mcp. It is excluded from the local ZIP and is never started by npm start; the ZIP remains a local, stdio-only install.

The checked-out source is version 0.2.2. It ships the same local runtime as 0.2.1, with a bundle README that also names the hosted endpoint. 0.2.1 added the therundown://brief resource, shared first-conversation instructions, and structured error and empty result explanations. The published source ZIP contains the same local runtime.

Download the versioned source bundle, verify its SHA-256 checksum, and extract it. The official ZIP SHA-256 is e82181727bb69bf0cae6edc215b4b3f432dc497e4afd32c7936b189931efd0a9. The ZIP manifest verifies every bundled source file. The ZIP README is generated from BUNDLE-README.md; this repository README also includes repository setup material. From the extracted ZIP directory:

npm ci --ignore-scripts
npm test

To run the checked-out source instead, use Node.js 22+ from this repository:

npm ci --ignore-scripts
npm test

For Claude Desktop's manual local configuration, add this to claude_desktop_config.json where supported and restart the client. Use absolute Node 22+ and server paths; this source ZIP is not a .mcpb desktop extension:

{
  "mcpServers": {
    "therundown-data": {
      "command": "/absolute/path/to/node",
      "args": ["/absolute/path/to/therundown-data-mcp-0.2.2/server.mjs"],
      "env": { "THERUNDOWN_API_KEY": "YOUR_API_KEY" }
    }
  }
}

For Cursor, use the global ~/.cursor/mcp.json and make the key available in the environment that launches Cursor:

{
  "mcpServers": {
    "therundown-data": {
      "type": "stdio",
      "command": "/absolute/path/to/node",
      "args": ["/absolute/path/to/therundown-data-mcp-0.2.2/server.mjs"],
      "env": { "THERUNDOWN_API_KEY": "${env:THERUNDOWN_API_KEY}" }
    }
  }
}

Client references: local MCP servers, Cursor.

Replace the path and key locally. Use your client's secret storage or inherited environment when available. Do not commit a filled-in client config. The server reads THERUNDOWN_API_KEY from its process environment and sends it only as X-TheRundown-Key; keys are never accepted as tool arguments. stdout contains only MCP protocol messages. A missing key exits with a generic message on stderr.

The six tools are:

list_markets keeps catalog discovery and can also discover markets available for one sport_id and date; date-based discovery rejects live because that endpoint does not classify live markets. Event queries always use main_line=true, hide_closed=true, and include=all_periods. list_futures is an Ultra+ competition endpoint with scoped defaults [1141] and [19,23], opaque cursor pagination, public schedule/settlement fields, and open per-affiliate main lines without line IDs. Defaults for dated event tools remain markets [1,2,3] and affiliates [19,23]. Pass live markets [41,42,43] explicitly. Retired affiliate 27 is rejected and excluded from discovery.

First conversation

Use TheRundown to list current sports and affiliates. Find MLB (sport 3).
For today's UTC date, list events with market_ids [1,2,3]
and affiliate_ids [19,23]. Select an event ID from that response and
call get_main_lines with the same filters.
Show the source URL, each book's line value and price updated_at,
and the returned usage headers. Explain empty results without inventing odds.

npm test runs offline. To check actual Product API data, privately set THERUNDOWN_API_KEY and run npm run smoke. The default checks pre-match [1,2,3] for MLB and affiliates [19,23]. Free includes delayed pre-match odds and excludes live odds, props/alternates, and history; a source catalog row does not grant access to it.

With an eligible key, THERUNDOWN_SMOKE_LIVE=1 npm run smoke also requests live [41,42,43]. THERUNDOWN_SMOKE_DATE=YYYY-MM-DD and THERUNDOWN_SMOKE_SPORT_ID select the dated scope. For a bounded Ultra+ competition check, set THERUNDOWN_SMOKE_FUTURES=1 and a sport such as 40 (PGA) or 41 (Formula 1); it requests only market 1141 and affiliates 19,23. The check has a 60-second deadline, verifies all six tool names, and reports its UTC check time, scope, selected event ID, source URLs, usage, and counts. Require status: "ok", six tools, and positive event/main-line counts. Empty data is inconclusive and exits 2. These requests are opt-in and metered.

Usage, API plan delays, and entitlements apply to every request. Catalog, date-market, event, and main-line pages paginate locally, so each page refetches a snapshot and is separately metered. list_futures uses the API's upstream opaque cursor and page limit; each cursor page is still a metered request and is only a partial competition listing when has_more is true. Results expose safe source URLs, retrieval timestamps, API usage headers, and per-price updated_at; a retrieval timestamp is not evidence that a price is fresh.

Agent brief and errors (since 0.2.1)

Read therundown://brief through MCP resources for the current Build with AI rules and first conversation. Initialization returns the same instructions; neither operation calls the Product API.

HTTP failures return status, plan, missing_entitlement, required_plan, retry_after (seconds), remaining_points, monthly_remaining_points, and limit_reason, alongside the safe source URL, retrieval time, and usage headers. Fields stay null when the API does not supply a recognized value. The server does not guess the current plan from a denied feature. Raw upstream error bodies are never returned, and errors do not trigger automatic retries.

An empty successful result retains its normal data shape and adds empty with a code, explanation, and request scope. Dated results report the sport, date, and date-boundary offset (UTC at zero); a page beyond existing results is identified separately from an empty slate. Empty odds do not establish absent coverage.

See the setup guide, DESIGN.md, authentication, and billing. Read the OpenAPI specification, sports catalog, markets catalog, affiliates catalog, TheRundown llms.txt, and documentation llms.txt for current public contracts and IDs.
