FLUX MCP MCP server

The official FLUX MCP server allows AI agents to generate, edit, vary, and browse images and video using Black Forest Labs' FLUX models. It supports OAuth sign-in for authentication, enabling users to pay directly to BFL without managing API keys. The server exposes tools for text-to-image, image editing, virtual try-on, and video generation within MCP-compatible clients like Claude and Cursor.

Endpoint and access

OAuth sign-in: the first time you connect, your client opens the vendor's own authorization prompt in a browser.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http flux-mcp https://mcp.bfl.ai

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add flux-mcp --url https://mcp.bfl.ai

Cursor

Merge this server into .cursor/mcp.json in your project, then enable flux-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "flux-mcp": {
      "url": "https://mcp.bfl.ai"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "flux-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.bfl.ai",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start flux-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "flux-mcp": {
      "type": "http",
      "url": "https://mcp.bfl.ai"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http flux-mcp https://mcp.bfl.ai

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "flux-mcp": {
      "url": "https://mcp.bfl.ai"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "flux-mcp": {
      "serverUrl": "https://mcp.bfl.ai"
    }
  }
}
