Connect dfsOS to your AI assistant

dfsOS is an MCP server your assistant can call for DraftKings-only contest history, athlete news and DFS lessons: free questions need no account, and linking your dfsOS account adds what your plan includes on the site.

Data and privacy

When you ask a question, your AI assistant sends mcp.dfsos.com only the arguments the tool needs: a sport, dates, a contest or athlete name, and, for linked accounts, your dfsOS sign-in token. dfsOS does not receive your chat history.

Every answer honours dfsOS public-profile opt-outs, data removal requests and winnings visibility settings. Usernames that opted out are masked and counted, never shown.

dfsOS reports what has happened in DraftKings contests. It never recommends a lineup.
