Higgsfield MCP server & Claude connector

Does Higgsfield have an official MCP server or Claude connector?

Official

As of October 2026, Higgsfield documents an official hosted MCP server at mcp.higgsfield.ai/mcp on its own help center. You sign in with your Higgsfield account via the browser, with no API key, and it requires an active paid subscription. Claude's connector directory listing was not found, so it is added as a custom connector.

Higgsfield's help center routes Claude Code through the Higgsfield CLI rather than the raw URL: the agent installs it, then you sign in in the browser.

Safety check

  • Pass

    Publisher verified

    Endpoint is on higgsfield.ai (mcp.higgsfield.ai) and is documented on Higgsfield's own help center and higgsfield.ai/mcp page.

  • Pass

    Auth model

    Browser sign-in to the Higgsfield account and authorization; the help center says no API key is needed. Exact OAuth flavor is not stated.

  • Flag

    Write and delete access

    Tools generate and process media and spend paid credits. Individual tool names and any read-only mode are not documented, so scope could not be assessed.

  • Unknown

    Tool-description injection scan

    Server is closed source and the help center names no tool ids; tool description text was not reviewed. Marketing pages contain example user prompts only, nothing aimed at the AI that changes its behavior was found.

  • Unknown

    Repo maintenance

    Hosted service; no vendor MCP repository found. (Higgsfield's CLI and skills are referenced as @higgsfield/cli and higgsfield-ai/skills, not checked.)

  • ⚠ Auth model: Uses a long-lived Higgsfield API key ID and secret in environment variables.
  • ⚠ Write and delete access: Generation tools spend credits and delete_character removes trained characters; no read-only mode seen in the README.
