# `fastmcp.server.auth.providers.scalekit`


Scalekit authentication provider for FastMCP.

This module provides ScalekitProvider - a complete authentication solution that integrates
with Scalekit's OAuth 2.1 and OpenID Connect services, supporting Resource Server
authentication for seamless MCP client authentication.


## Classes

### `ScalekitProvider` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/auth/providers/scalekit.py#L23" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>


Scalekit resource server provider for OAuth 2.1 authentication.

This provider implements Scalekit integration using resource server pattern.
FastMCP acts as a protected resource server that validates access tokens issued
by Scalekit's authorization server.

IMPORTANT SETUP REQUIREMENTS:

1. Create an MCP Server in Scalekit Dashboard:
   - Go to your [Scalekit Dashboard](https://app.scalekit.com/)
   - Navigate to MCP Servers section
   - Register a new MCP Server with appropriate scopes
   - Ensure the Resource Identifier matches exactly what you configure as MCP URL
   - Note the Resource ID

2. Environment Configuration:
   - Set SCALEKIT_ENVIRONMENT_URL (e.g., https://your-env.scalekit.com)
   - Set SCALEKIT_RESOURCE_ID from your created resource
   - Set BASE_URL to your FastMCP server's public URL

For detailed setup instructions, see:
https://docs.scalekit.com/mcp/overview/


**Methods:**

#### `get_routes` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/auth/providers/scalekit.py#L156" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
get_routes(self, mcp_path: str | None = None) -> list[Route]
```

Get OAuth routes including Scalekit authorization server metadata forwarding.

This returns the standard protected resource routes plus an authorization server
metadata endpoint that forwards Scalekit's OAuth metadata to clients.

**Args:**
- `mcp_path`: The path where the MCP endpoint is mounted (e.g., "/mcp")
This is used to advertise the resource URL in metadata.
