# API overview

> Authentication, endpoint groups, and OpenAPI source for Pcnaid MCP Hub.

The Pcnaid MCP Hub API provides a comprehensive set of endpoints to manage your MCP servers, groups, users, and more. The API is divided into two main categories:

* **MCP Endpoints**: These are the primary endpoints for interacting with your MCP servers. They provide a unified interface for sending requests to your servers and receiving responses in real-time.
* **Management API**: These endpoints are used for managing the Pcnaid MCP Hub instance itself. This includes managing servers, groups, users, and system settings.

All API endpoints are available under the `/api` path. For example, the endpoint to get all servers is `/api/servers`.

Authentication is required for most Management API endpoints. See the [Authentication](/nodes/integrations/pcnaid-mcp-hub/developer/api/auth) section for more details.

## OpenAPI source

The OpenAPI source for generated endpoint pages is `developer/api/openapi.yaml`. Mintlify can auto-populate endpoint pages from this file.
