Summary
AWS walks through building a FastMCP-based ecommerce MCP server (product search, orders, reviews, returns) deployed on Bedrock AgentCore Runtime with DynamoDB and Cognito, then connecting it to Mistral AI Studio's "Vibe" agent via two-layer JWT/OAuth 2.1 authentication. It's a concrete cross-vendor MCP interoperability reference between AWS and Mistral.
Key Takeaways
- Demonstrates a full OAuth 2.1 login flow that removes manual 24-hour token rotation between an MCP server and a third-party model studio.
- Bedrock AgentCore Runtime handles container management and token validation for the MCP server.
- Deployed via AWS CDK, with source published at
aws-samples/mistral-on-aws. - A rare concrete example of MCP working across AWS-hosted infrastructure and a non-AWS model provider's agent studio.
