awesome-agent-protocols

Guide agent harness engineering toward the right AI agent protocol standards (MCP, A2A, ACP, AG-UI, AP2, x402, etc.) instead of reinventing. Analyzes what you're building, recommends protocols, pulls spec details and wire-message examples, checks compliance, and surfaces contribution opportunities. Triggers: '/agent-protocols', 'which protocol', 'should I use MCP or', 'what protocol for', 'agent protocol', 'protocol selection', 'MCP vs A2A', 'wire protocol for agents', 'agent interop', 'agent standard', 'extend MCP', 'contribute to A2A', 'protocol compliance', 'agent transport', 'agent discovery'. Self-improving: every run ends with a gotcha review.
