Kong/kong
Kong Gateway is a cloud-native, scalable API gateway that manages API, AI LLM, and Model Context Protocol (MCP) traffic with advanced security, observability, and extensibility features.
GongRzhe/A2A-MCP-Server
A2A MCP Server is an integration layer between two agent protocols. On one side, the Model Context Protocol, which standardises how an assistant reaches external tools and data. On the other, Google's Agent-to-Agent protocol, which standardises communication between independent agents over a JSON-RPC interface. The server presents A2A capabilities as ordinary MCP tools, so a client such as Claude Desktop can discover available A2A agents, register them, send messages and tasks to them, and track task state — all without implementing A2A itself. That makes the bridge useful in a mixed estate where some capabilities are exposed as MCP servers and others as A2A agents: the client speaks one protocol and reaches both. The implementation is Python, Apache-2.0 licensed, and listed on Smithery for installation. Both task submission and task management are covered, which matters because A2A models long-running work as a task with a lifecycle rather than a single request and response. One caveat should be weighed before adopting it: the GitHub repository is archived, so it is read-only and no longer receiving fixes or protocol updates, and both MCP and A2A have continued to change since. The audience is anyone experimenting with cross-protocol agent interoperability, primarily as a reference implementation.
