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
