# higgsfield-mcp-unified A local-first [Model Context Protocol](https://modelcontextprotocol.io) server for [Higgsfield AI](https://higgsfield.ai/). It puts **85 models from the official Higgsfield API**: Seedance 2.5, Kling 3.0 / O3 / Omni, Wan 3, Genjutsu, Cinema Studio 4, Soul, Marketing Studio, Recraft, Ideogram and more. Soul character training, webhooks, cost estimates and preset catalogs sit behind the same typed tool surface, which any MCP client (Claude Desktop, Claude Code, Cursor, …) can use. An opt-in experimental backend adds 34 consumer-app models such as Sora 2, Veo 3 and Nano Banana. > **Status: alpha.** > The official-API path follows [docs.higgsfield.ai](https://docs.higgsfield.ai/docs) and has been cross-checked against the [open.higgsfield.ai](https://open.higgsfield.ai/explore) console. ## Why this over the hosted MCP The official hosted MCP (`mcp.higgsfield.ai`) runs on Higgsfield's servers behind OAuth. This one runs **on your machine** with your API key, and adds: - **The full API catalog, typed.** Every documented endpoint has its parameters, enums, ranges and defaults, so the model picks valid values before spending credits. - **Discovery that costs nothing.** `estimate_cost` prices a request, while `recommend_model`, `validate_params` and `preflight_check` work without running a generation. - **Structured output.** Every tool returns a schema'd result (`outputSchema` + `structuredContent`), not an opaque blob. - **Built-in reliability.** - Every submit carries an idempotency key, so retries (backoff with jitter, plus a circuit breaker) never double-charge. - Errors come back as typed cases: auth, out of credits, concurrency limit, bot challenge, network. - **Webhooks and every output type.** It surfaces images, video, audio and the extra video/3D files (zip, mov, jsx, fbx, ply). ## Install The package is [`higgsfield-mcp-unified`](https://pypi.org/project/higgsfield-mcp-unified/) on PyPI, and its command is `higgsfield-mcp`.
