## 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`.
