Fal Ai Mcp Server

Fal AI MCP Server

An MCP (Model Context Protocol) server to use the fal.ai APIs to generate images and videos. This is a barebones server that anyone can extend to use different fal.ai models and API endpoints.

Usage

Install uv and add the server to an MCP config using uvx:

{
    "name": "fal-ai-mcp-server",
    "command": "uvx",
    "args": [
        "fal-ai-mcp-server"
    ],
    "env": {
        "FAL_KEY": "your-key",
        "SAVE_MEDIA_DIR": "path/to/save/images"
    }
}

or clone the repo and use uv with a directory:

{
    "name": "fal-ai-mcp-server",
    "command": "uv",
    "args": [
        "--directory",
        "path/to/root/dir/",
        "run",
        "main.py"
    ],
    "env": {
        "FAL_KEY": "your-key",
        "SAVE_MEDIA_DIR": "path/to/save/images"
    }
}

Releasing a New Version

To release a new version of the package to PyPI, create and push a new Git tag:

1. Checkout the main branch and get the current version:

``bash git checkout main git pull origin main git describe --tags ``

1. Create and push a new Git tag:

``bash git tag v0.2.0 git push origin v0.2.0 ``

The GitHub Actions workflow will automatically build and publish the package to PyPI when a new tag is pushed. The python package version number will be derived directly from the Git tag.
