# FastMCP Authentication Middleware This is a simple authentication middleware for FastMCP that uses JWT tokens for user authentication. AWS Cognito is used as the identity provider, from which users authenticate and receive a JWT token. The requested token is then passed in the `Authorization` header of the request to the FastMCP server. The server then verifies the token using the public key from AWS Cognito.  ## Pre-requisites You will need to create a Cognito user pool and a user pool client in AWS then set the following environment variables: Create a `.env` file in the root directory with the following variables: ```env USER_POOL_CLIENT_ID=<YOUR_USER_POOL_CLIENT_ID> USER_POOL_CLIENT_SECRET=<YOUR_USER_POOL_CLIENT_SECRET> COGNITO_USER_POOL_ID=<YOUR_USER_POOL_ID> ``` ## Starting the server ```bash uv sync source .venv/bin/activate ``` This will create a virtual environment and install all the required packages. ```bash python src/mcp_services/auth_mcp/server.py ``` ## Testing the server ```bash python src/test.py ```
