## Features
- **Authentication** built in, using your existing FastAPI dependencies!
- **FastAPI-native:** Not just another OpenAPI -> MCP converter
- **Zero/Minimal configuration** required - just point it at your FastAPI app and it works
- **Preserving schemas** of your request models and response models
- **Preserve documentation** of all your endpoints, just as it is in Swagger
- **Flexible deployment** - Mount your MCP server to the same app, or deploy separately
- **ASGI transport** - Uses FastAPI's ASGI interface directly for efficient communication
## Hosted Solution
If you prefer a managed hosted solution check out [tadata.com](https://tadata.com).
## Installation
We recommend using [uv](https://docs.astral.sh/uv/), a fast Python package installer:
```bash
uv add fastapi-mcp
```
Alternatively, you can install with pip:
```bash
pip install fastapi-mcp
```
## Basic Usage
The simplest way to use FastAPI-MCP is to add an MCP server directly to your FastAPI application:
```python
from fastapi import FastAPI
from fastapi_mcp import FastApiMCP
app = FastAPI()
mcp = FastApiMCP(app)
# Mount the MCP server directly to your FastAPI app
mcp.mount()
```
That's it! Your auto-generated MCP server is now available at `https://app.base.url/mcp`.
## Documentation, Examples and Advanced Usage
FastAPI-MCP provides [comprehensive documentation](https://fastapi-mcp.tadata.com/). Additionaly, check out the [examples directory](examples) for code samples demonstrating these features in action.
## FastAPI-first Approach
FastAPI-MCP is designed as a native extension of FastAPI, not just a converter that generates MCP tools from your API. This approach offers several key advantages:
- **Native dependencies**: Secure your MCP endpoints using familiar FastAPI `Depends()` for authentication and authorization
- **ASGI transport**: Communicates directly with your FastAPI app using its ASGI interface, eliminating the need for HTTP calls from the MCP to your API
- **Unified infrastructure**: Your FastAPI app doesn't need to run separately from the MCP server (though [separate deployment](https://fastapi-mcp.tadata.com/advanced/deploy#deploying-separately-from-original-fastapi-app) is also supported)
This design philosophy ensures minimum friction when adding MCP capabilities to your existing FastAPI services.
