FAQ from Fal AI MCP Server

What is the Fal AI MCP Server?

It is an MCP server that acts as a bridge to fal.ai’s image and video generation APIs. It is designed to be minimal and easily customized for different fal.ai models.

What prerequisites do I need to run it?

You need Python, the uv package manager, and a valid FAL_KEY from fal.ai. Optionally, set SAVE_MEDIA_DIR to specify where media files will be stored.

How do I configure the server in my MCP client?

Add a JSON entry to your MCP client’s config with the command uvx and arguments fal-ai-mcp-server, plus the required environment variables FAL_KEY and SAVE_MEDIA_DIR. Alternatively, point uv to a cloned repository directory.

Can I test the server without a full MCP client?

Yes, the README recommends using mcp-client-for-testing with uvx. An example command is provided that calls an echo tool to verify the server is working.

Is there a way to extend the server to use other fal.ai models?

Yes, the README explicitly states it is a barebones server that anyone can extend to use different fal.ai models and API endpoints.
