Higgsfield

Higgsfield's official MCP server lets agents generate images, videos, and audio with Higgsfield's models, using your Higgsfield account. The endpoint is https://mcp.higgsfield.ai/mcp over HTTP.

Setting up​

  1. In Willow, go to MCP Servers → + Add MCP server and find the Higgsfield card with the Official badge.

  2. Click + Use, then complete the OAuth prompt as a Higgsfield user. If you're already signed in to higgsfield.ai, the sign-in step is automatic.

Willow registers itself with Higgsfield automatically using dynamic client registration, so there is no app, client ID, or API key to create beforehand.

note

Higgsfield MCP requires an active paid Higgsfield subscription.

Credits​

Generations made through the MCP server use your Higgsfield plan credits at standard rates, and they appear in your Assets on higgsfield.ai, tagged with MCP as the source. Unlimited model access and free generations apply only on higgsfield.ai, not through MCP. Higgsfield has no credit cap for agents, so it suggests starting each session with: "Before generating anything, tell me the credit cost and wait for my confirmation."
