Overview

What is fal.ai MCP Server?

fal.ai MCP Server is a Model Context Protocol (MCP) server that enables interaction with fal.ai models and services. It allows you to list, search, generate content, manage queues, and upload files to fal.ai’s CDN, all through a standardized MCP interface. It is intended for developers using MCP-compatible clients like VS Code, Claude Desktop, or Antigravity.

How to use fal.ai MCP Server?

Install Python 3.10+, clone the repository, create a virtual environment, and install dependencies from requirements.txt. Set the FAL_KEY environment variable with your fal.ai API key. Then configure your MCP client (e.g., Claude Desktop, VS Code) to point to the venv’s Python interpreter and the main.py script. Use the provided tools (models, search, generate, result, etc.) to interact with fal.ai models.

FAQ from fal.ai MCP Server

What Python version and dependencies are required?

Python 3.10+ is required. Dependencies include fastmcp, httpx, and aiofiles.

Why doesn’t Docker work for MCP integration?

MCP servers use stdio transport and must be spawned as a child process by the client. Docker containers lack an active stdin connection, so the server exits immediately. Direct Python execution is the only supported approach.

How do I set my fal.ai API key?

Set the FAL_KEY environment variable, or create a .env file in the project root with FAL_KEY=your_key_here. The server loads it automatically.

Which MCP clients are supported?

The server is designed for Claude Desktop, VS Code, and Antigravity. Configuration JSON must point to the venv Python interpreter and the main.py script.

What tools does the server expose?

The server provides tools for listing models (models), searching (search), getting schemas (schema), generating content (generate), managing queues (result, status, cancel), and uploading files (upload).
