Authentication
AWS Sign-In OAuth access for AWS MCP Server oauth2 discovered Set up OAuth ↗
OAuth · resolves from well-known metadata

Use an OAuth-capable MCP client and connect it to an AWS MCP Server endpoint such as https://aws-mcp.us-east-1.api.aws/mcp?oauth=initialize or the Marketplace endpoint. AWS documents that AWS MCP Server supports OAuth authorization through AWS Sign-In and that supported redirect URIs for Dynamic Client Registration are built in, so the MCP client registers itself and you approve access in the browser. Start from Configure OAuth access to AWS MCP Server and OAuth 2.1 authentication for AWS MCP Server.

AWS IAM credentials for SigV4-signed AWS MCP Server access aws_sigv4 discovered Get keys ↗
Authorization: <credential>

Configure AWS credentials for the account/profile you want to use, typically via the AWS CLI, then use the MCP Proxy for AWS so requests to AWS MCP Server are signed with SigV4. AWS documents this as the advanced authentication path for terminal and IDE clients. Start from Setting up the AWS MCP Server and follow the SigV4 option described there.
