2AgentOS v1.14.7 — MCP & A2A Interoperability Validation Suite.

4Validates that AgentOS's MCP and A2A protocol implementations are

5standards-compliant and interoperable with the broader ecosystem.

7Covers:

8- MCP protocol compliance (server/client)

9- A2A protocol compliance (Agent-to-Agent)

10- Cross-framework interop testing

11- Protocol conformance reports
