rapidoddsapi-mcp

MCP server for RapidOddsAPI. Gives an AI assistant bookmaker odds, live scores, arbitrage and value bets.

Built on the official rapidoddsapi Python SDK.

Setup

You need an API key from the dashboard. Keys start with oa_.

Claude Desktop

Add this to claude_desktop_config.json:

{
  "mcpServers": {
    "rapidoddsapi": {
      "command": "uvx",
      "args": ["rapidoddsapi-mcp"],
      "env": {
        "RAPIDODDSAPI_API_KEY": "oa_your_api_key_here"
      }
    }
  }
}

The config file lives at ~/Library/Application Support/Claude/ on macOS and %APPDATA%\Claude\ on Windows. Restart Claude Desktop after editing it.

Anything else that speaks MCP

RAPIDODDSAPI_API_KEY=oa_your_api_key_here uvx rapidoddsapi-mcp

It speaks stdio.

Tools

Credits are charged only when games come back, so a query that matches nothing is free. Every response ends with what it cost and what is left.

Credits

The free tier is 250 credits for the life of the account, with no monthly reset, so the defaults are deliberately narrow:

• A sport is always required. There is no way to request every sport at once.
• Bookmakers default to five, one credit group, chosen for the sport's region.
• Market types default to one.

That makes a typical question cost 1 credit. Both arguments multiply, so asking for nine market types across eighteen bookmakers is 36. The tool descriptions say so, which is what keeps the model from doing it uninvited.

find_arbitrage and find_value_bets default to ten bookmakers, 2 credits, because both need books that disagree and five rarely spread far enough.

Markets

find_arbitrage and find_value_bets handle any market whose bets have two sides: head_to_head and its period variants, soccer's draw_no_bet, totals, handicaps, team totals and player props. Each line is its own bet, so a totals market can return several results for one game.

Three-way markets return an error explaining why rather than an empty list, since "nothing found" would read as "no opportunities".

find_value_bets takes devig for where the fair price comes from. The default, "all", de-vigs every bookmaker fetched and averages the result, which needs no view on which book is sharp. Naming one, devig="Pinnacle", measures every other book against that one instead: tighter, but only on markets that book prices. A consensus needs four bookmakers on the same line, so on thin markets naming a book finds bets that averaging cannot.

Market keys vary by sport. list_sports(sport) returns the valid ones and costs nothing.

Bookmakers

Names are odds feeds, not brands. Many brands share one feed and quote identical prices, so Ladbrokes covers Neds and Betmakers covers the 26 brands running on it. A brand name that is not a feed returns nothing.
