Clincher
Use with AI

Run it from
the AI you already use.

Connect Clincher to your AI assistant. Any assistant that supports connectors works. Then ask in plain words and it does the work: brackets, players, results, the next round. Free.

For teams: https://teams.heyclincher.com/mcp. Add both if you run both.

Connect in a minute

Claude

  1. Open Settings, then Connectors.
  2. Add a custom connector and paste the address above.
  3. Choose Connect and sign in with your email or phone. No password, just a code.
  4. Approve, and you're set: web, desktop and mobile.

ChatGPT

  1. Open Settings and find Connectors (on some plans it's under advanced or developer options).
  2. Create a connector and paste the address above.
  3. Sign in with your email or phone, then approve.
  4. Turn the connector on in a chat and ask away.

Muse

  1. In Muse, ask it to add a custom connector for Clincher with this address:
    https://heyclincher.com/mcp
  2. When it asks how to sign in, use your email or phone code. If it asks for a key instead, make one on your account page and paste that.
  3. Then ask away. Muse is new, so how it adds connectors is still changing.

Coding tools

  1. Claude Code:
    claude mcp add --transport http clincher https://heyclincher.com/mcp
  2. Then type /mcp and sign in when it asks.
  3. Muse Code, editors and other coding agents: add a remote (streamable HTTP) MCP server named clincher with the address above. Sign in when prompted, or send an API key from your account page as a Bearer token.

Any other assistant

  1. Easiest: ask it to set this up for you. Paste this in, and it'll walk you through its own menus:
    Help me add Clincher as a connector (MCP server). Its address is https://heyclincher.com/mcp
  2. Or do it yourself: look in its settings for Connectors, Integrations, Tools or MCP servers.
  3. Add a custom or remote one and paste the address above.
  4. Sign in with your email or phone when it asks, then approve.
  5. No connectors in your assistant yet? On Pro you can link your phone on your account page and text Clincher instead.

Menus move around as these apps update, and connector support depends on your plan with them. Your assistant acts as you: it can do what you can do here, nothing more. Disconnect it any time from your account page.
