Developers & AI apps
Combat Edge in Claude
The Combat Edge connector gives Claude and other AI apps that support the Model Context Protocol (MCP) read-only access to the Combat Edge MMA database: fighter profiles and records, the promotion-blind Combat Edge Elo with full history, division rankings, event cards and results, round-by-round stat leaders, and the Combat Edge prediction model with its public accuracy record.
Ask things like "Break down the main event of the next UFC card", "Who has the best striking differential at lightweight over the last three years?" or "How has the Combat Edge model done this year?" and Claude answers from Combat Edge data, with links back to the pages.
Connect
You need a Combat Edge account; a free one works. Create one if you don't have it.
Claude (web, desktop and mobile)
- In Claude, open Settings → Connectors and choose Add custom connector.
- Name it Combat Edge and enter the server URL:
https://combat-edge.com/api/mcp - Choose Connect, sign in to Combat Edge and select Allow.
On Team and Enterprise plans, an owner may need to add the connector for the organization first.
Claude Code
claude mcp add --transport http combat-edge https://combat-edge.com/api/mcpThen run /mcp in Claude Code and choose Authenticate to sign in. Premium members can use their API key instead (below).
Other MCP clients
Point any client that supports remote MCP servers over Streamable HTTP at https://combat-edge.com/api/mcp. Sign-in uses OAuth 2.1 with PKCE and dynamic client registration; discovery starts at https://combat-edge.com/.well-known/oauth-protected-resource.
API key (Premium)
For scripts and developer tools that can't do an OAuth sign-in, Premium members can create a personal key under Account → Predictions data feed and send it as a bearer token:
claude mcp add --transport http combat-edge https://combat-edge.com/api/mcp \
--header "Authorization: Bearer ce_pf_…"The key is the same one that unlocks the predictions feed, and it stops working if Premium ends. Replacing or revoking it in your account takes effect immediately.

Privacy and permissions
- A connected app can read Combat Edge data and whether your account is free or Premium. It can't see your email, password or payment details, and it can't change your account, picks, follows or comments.
- The connector receives only the arguments of each tool call (a fighter name, an event). It never receives your conversation.
- We store the sign-in grant (as a hashed token) and the time it was last used, so you can see and disconnect apps under Account → Connected apps. Deleting your account deletes them.
- Full details: Privacy policy.
