### Description (declared)

# OpenAPI to MCP Converter (Python)

A Python library to automatically generate MCP (Model-View-Controller Protocol) servers from OpenAPI specifications.

This library allows you to expose any API with an OpenAPI v3 specification as an MCP-compliant server, making it easy to integrate with AI agents and other MCP-enabled tools.

## Features

- **Dynamic Conversion**: Generate MCP servers from any public OpenAPI v3 specification URL.
- **Path Filtering**: Selectively expose a subset of API endpoints.
- **Dynamic Upstream URL**: Forward requests to a different base URL than the one in the OpenAPI spec.
- **Authentication Forwarding**: Pass authentication headers to the upstream API.
- **`$ref` Resolution**: Automatically resolves JSON references (`$ref`) in the OpenAPI spec for complete schema definitions.
- **Security**: Built-in SSRF protection with a configurable domain whitelist.
- **Framework Integration**: Plug-and-play integration with FastAPI.

## Installation

```bash
pip install openapi-to-mcp
```

## Quick Start - FastAPI Integration

Here's how to add an MCP server to your existing FastAPI application. This example sets a static OpenAPI spec URL and enables security.

```python
from fastapi import FastAPI
from openapi_to_mcp.fastapi import add_mcp_route

app = FastAPI()

# Add the MCP route
# This will expose an MCP server at /mcp
add_mcp_route(
    app,
    openapi_url="https://petstore.swagger.io/v2/swagger.json",
    allowed_domains=["petstore.swagger.io"]  # SSRF Protection
)

@app.get("/")
def read_root():
    return {"Hello": "World"}
```

## Advanced Configuration

You can configure the MCP server statically when you initialize it or dynamically using query parameters.

### Static Configuration

Pass a configuration object to `add_mcp_route`:

- `route_prefix` (optional, default: `/mcp`): The base path for the MCP server.
- `openapi_url` (optional): A default OpenAPI specification URL.
- `allowed_domains` (optional, default: `[]`): A list of allowe…
