Generate images using Replicate's Flux Schnell model.

This MCP server provides image generation capabilities using the Flux Schnell model on Replicate.

npm install -g @modelcontextprotocol/sdk@latest

- Clone this repository to your MCP servers directory:

cd ~/Documents/Cline/MCP git clone https://github.com/yourusername/flux-img-mcp.git cd flux-img-mcp npm install

- Add the server configuration to your MCP settings file (either global or workspace):

{ "mcpServers": { "flux-img": { "command": "node", "args": ["/path/to/flux-img-mcp/build/index.js"], "env": { "REPLICATE_API_TOKEN": "your-replicate-api-token" }, "disabled": false, "alwaysAllow": [] } } }

The server requires the following environment variable:

- REPLICATE_API_TOKEN: Your Replicate API token. You can get this from yourReplicate account settings.

Once installed and configured, the server provides the following tool:

Generates an image using the Flux Schnell model based on a text prompt.

- prompt(string, required): Text description of the desired image

<use_mcp_tool> <server_name>flux-img</server_name> <tool_name>generate_image</tool_name> <arguments> { "prompt": "A beautiful sunset over mountains" } </arguments> </use_mcp_tool>

The tool will return a JSON response containing:

- status: The status of the generation request
- output: The URL of the generated image (if successful)
- error: Any error message (if failed)
- Modify the source code insrc/index.ts
- Rebuild the server:npm run build
