Installation
Cursor Configuration
There are two ways to configure the MCP server in Cursor:
Project Configuration
For tools specific to a project, create a .cursor/mcp.json file in your project directory:
{
  "mcpServers": {
    "mcp-flux-schnell": {
      "command": "node",
      "args": ["/path/to/mcp-flux-schnell/build/index.js"],
      "env": {
        "FLUX_API_URL": "your flux api url",
        "FLUX_API_TOKEN": "your flux api token",
        "WORKING_DIR": "your working directory"
      }
    }
  }
}
This configuration will only be available within the specific project.
Global Configuration
For tools that you want to use across all projects, create a ~/.cursor/mcp.json file in your home directory with the same configuration:
{
  "mcpServers": {
    "mcp-flux-schnell": {
      "command": "node",
      "args": ["/path/to/mcp-flux-schnell/build/index.js"],
      "env": {
        "FLUX_API_URL": "your flux api url",
        "FLUX_API_TOKEN": "your flux api token",
        "WORKING_DIR": "your working directory"
      }
    }
  }
}
This makes the MCP server available in all your Cursor workspaces.
