A Model Context Protocol (MCP) server that automatically generates tools from OpenAPI/Swagger specifications, allowing MCP Clients (e.g. Claude Desktop) to interact with any REST API.

## Features

- 🔄 **Automatic Tool Generation**: Converts OpenAPI specs into callable MCP tools
- 🔐 **Multiple Authentication Types**: Bearer tokens, API keys, Basic auth, or no auth
- 🎯 **Path Filtering**: Include/exclude specific API endpoints using regex patterns
- 🌐 **Flexible Spec Loading**: Supports both JSON and YAML OpenAPI specifications
- 🔒 **Environment Variables**: Secure credential management with `${VAR_NAME}` expansion
- 🛡️ **Secure by Default**: Only GET (read-only) operations enabled by default

## Quick Start

### Minimal Usage

The easiest way to get started is with a simple command line argument:

**1. Configure Claude Desktop**

Add this to your Claude Desktop `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "petstore": {
      "command": "uvx",
      "args": [
        "mcp-this-openapi",
        "--openapi-spec-url",
        "https://petstore3.swagger.io/api/v3/openapi.json"
      ]
    }
  }
}
```

**2. Try it in Claude**

Once configured, you can ask Claude things like:
- "What pet operations are available?"
- "Get information about pet with ID 1" 
- "Show me the pet store inventory"

**🔒 Security Note**: By default, only `GET` (read-only) operations are enabled for safety.

### Advanced Usage (Configuration File)

For authentication, filtering, or other advanced features, create a YAML configuration file:
