Implementation Reference
- index.js:297-315 (handler)Handler for the 'flux_models' tool within the CallToolRequestSchema request handler. Returns a JSON string of all supported FLUX models with their metadata including display name, kind, image acceptance, notes, and key inputs.if (name === "flux_models") { const models = Object.entries(FLUX_MODELS).map(([model, meta]) => ({ model, display: meta.display, kind: meta.kind, accepts_image: meta.accepts_image, notes: meta.notes, key_inputs: Object.keys(meta.inputs), })); return { content: [ { type: "text", text: JSON.stringify(models, null, 2), }, ], }; }
- index.js:206-213 (registration)Registration of the 'flux_models' tool in the ListToolsRequestSchema handler, including name, description, and empty input schema.{ name: "flux_models", description: "List supported FLUX models with usage notes and key inputs", inputSchema: { type: "object", properties: {}, }, },
- index.js:209-212 (schema)Input schema for the 'flux_models' tool, which takes no parameters (empty object).inputSchema: { type: "object", properties: {}, },
- index.js:17-103 (helper)Helper constant FLUX_MODELS defining metadata for all supported models, including display names, kinds, notes, input schemas, and image acceptance flags. Used by the handler to generate the response.const FLUX_MODELS = { "black-forest-labs/flux-1.1-pro-ultra": { display: "FLUX1.1 Pro Ultra", kind: "text-to-image", notes: [ "Highest quality, up to ~4MP; 'raw' mode for realism.", "Use when you need best composition/large output.", ], inputs: { prompt: { required: true, type: "string" }, raw: { required: false, type: "boolean" }, aspect_ratio: { required: false, type: "string" }, seed: { required: false, type: "integer" }, output_quality: { required: false, type: "number" }, go_fast: { required: false, type: "boolean" }, }, accepts_image: false, }, "black-forest-labs/flux-pro": { display: "FLUX1.1 Pro", kind: "text-to-image", notes: [ "Fast, reliable, commercial-grade default when Ultra not required.", ], inputs: { prompt: { required: true, type: "string" }, aspect_ratio: { required: false, type: "string" }, seed: { required: false, type: "integer" }, }, accepts_image: false, }, "black-forest-labs/flux-redux-dev": { display: "FLUX.1 Redux [dev]", kind: "image-variation", notes: [ "Variations/restyling while preserving key elements; mix image + text.", ], inputs: { image: { required: true, type: "file_or_url" }, prompt: { required: true, type: "string" }, strength: { required: false, type: "number" }, seed: { required: false, type: "integer" }, num_outputs: { required: false, type: "integer" }, }, accepts_image: true, }, "black-forest-labs/flux-fill-pro": { display: "FLUX.1 Fill [pro]", kind: "inpainting/outpainting", notes: ["Professional in/outpainting; provide mask for areas to change."], inputs: { image: { required: true, type: "file_or_url" }, mask: { required: false, type: "file_or_url" }, prompt: { required: true, type: "string" }, num_inference_steps: { required: false, type: "integer" }, guidance: { required: false, type: "number" }, seed: { required: false, type: "integer" }, }, accepts_image: true, }, "black-forest-labs/flux-depth-dev": { display: "FLUX.1 Depth [dev]", kind: "depth-guided editing", notes: [ "Structure-preserving edits/style transfer using depth; supply an image.", ], inputs: { image: { required: true, type: "file_or_url" }, prompt: { required: true, type: "string" }, seed: { required: false, type: "integer" }, }, accepts_image: true, }, "black-forest-labs/flux-canny-pro": { display: "FLUX.1 Canny [pro]", kind: "edge-guided generation", notes: [ "Control structure/composition with edges; ideal for sketches/wireframes → detailed images.", ], inputs: { image: { required: true, type: "file_or_url" }, prompt: { required: true, type: "string" }, seed: { required: false, type: "integer" }, }, accepts_image: true, }, };
