Connecting Higgsfield to Claude takes about 30 seconds with no API key or code. In Claude, go to Settings, Connectors, Add custom connector, paste the MCP URL https://mcp.higgsfield.ai/mcp, and authorize with your Higgsfield account. You need an active paid Higgsfield subscription and a Claude account. Once connected, you can generate images, videos, and audio, and use your Soul characters right from the conversation.

What do I need before connecting?

An active paid Higgsfield subscription and a Claude account (claude.ai or Claude Desktop). No API key, no code, no environment variables.

How do I connect in Claude.ai (web)?

  1. Open claude.ai, click your profile icon, and go to Settings → Connectors.
  2. Click Add custom connector.
  3. Paste the MCP server URL: https://mcp.higgsfield.ai/mcp
  4. Click Connect: a Higgsfield authorization window opens.
  5. Sign in to your Higgsfield account and authorize. If you're already logged in on higgsfield.ai, this step is automatic.
  6. Return to Claude: the Higgsfield connector appears in your active connectors list.

How do I connect in Claude Desktop?

The steps are the same: Settings (top menu, or Cmd+, on Mac) → Connectors → Add custom connector, paste https://mcp.higgsfield.ai/mcp, click Connect, and authorize with your Higgsfield account.

How do I verify the connection is working?

Start a new Claude conversation and ask "What is my Higgsfield credit balance?" or "List my recent Higgsfield generations." Claude will call the MCP tools and return your account data. If it responds without calling any tools, check your Connectors list and reconnect.
