A playground for Model Context Protocol (MCP) server built with TypeScript and Streamable HTTP transport with an OAuth Proxy for 3rd party authorization servers like Auth0.

Key capabilities

  • MCP 2025-06-18 Compliant — Full compliance with the latest MCP specification including SSE resumability, tool annotations, and structured content
  • MCP Server implementation — HTTP-Based Streamable transport using @modelcontextprotocol/sdk with HTTP transport, session management, and tool execution
  • SSE Resumability — Clients can reconnect with Last-Event-ID header to resume receiving events after connection breaks, powered by EventStore
  • OAuth authentication/3rd party authorization — Implements an OAuth server for MCP clients with RFC 8707 Resource Indicators and RFC 9728 authorization discovery, delegating to Auth0
  • Storage — Pluggable storage abstraction (Memory/Valkey) with EventStore for SSE event persistence and replay
  • Session Management — Support stateful sessions by using replay of initial request for distributed deployments
  • Security — Strict Origin validation to prevent DNS rebinding attacks, WWW-Authenticate headers for authorization discovery
  • aws-ecs: Investigate the ECS service, task and cloudwatch logs using AWS ECS, Cloudwatch Logs and Bedrock
