| 12 | The MCP works by applying a 3 step process: |
| 13 | |
| 14 | 1. It figures out the openapi identifier you need |
| 15 | 2. It requests a summary of that in simple language |
| 16 | 3. It determines which endpoints you need, and checks out how exactly they work (again, in simple language) |
| 17 | |
| 18 | Features |
| 19 | |
| 20 | - Get an overview of any OpenAPI specification |
| 21 | - Retrieve details about specific API operations |
| 22 | - Support for both JSON and YAML formats |
| 23 | - Tested with Claude Desktop and Cursor |
