🚀 Curated resources for Google's Agent Payments Protocol (AP2), A2A & x402 — blogs, videos, repos & specs. Contributions welcome!

A curated list of protocols and standards for AI agents — MCP, A2A, ACP, AG-UI, AP2, x402, and 50+ more, organized by stack layer

Local-first Agent communication runtime and gateway for A2A, MCP, E2EE messaging, REST/Webhook, and multi-agent collaboration.

AgentCard — standardized identity & capability schema for AI agents. Rust reference implementation: github.com/kwailapt/aevum/tree/main/crates/agent-card

Local-first MCP server for bounded, auditable handoffs between AI agents.

Top-tier contribution fork for A2A protocol interoperability: conformance patterns, enterprise rollout guidance, and maintainer-aligned docs.

Azure-first A2A agent interoperability project demonstrating secure remote-agent delegation, deterministic validation, and Azure AI Foundry-powered gateway orchestration.

A simple but powerful roadmap planner with graph and storyboard function.

Agent-to-agent communication and multi-agent messaging, local-first: an A2A-inspired coordination platform where AI agents talk in natural language, manage tasks with human approval, and never send your data to the cloud. 65-command API, Python client, web UI, encrypted backups.

A clean reference implementation of the Agent-to-Agent (A2A) protocol: specialized AI agents that discover each other and collaborate over JSON-RPC 2.0. Python · FastAPI · Pydantic.

Experimental trust and governance ideas for autonomous AI agents — captcha, permit, mesh, eval, memory.

Move useful working context from Agent A to Agent B — local-first context handoff for AI agents.

Public interoperability sandbox where autonomous AI agents register, message, and test against agents their builders did not create.

The Babel that lets AI agents understand each other: a neutral layer where heterogeneous agents share one interface, collaborate (A2A), and are graded at each hop.

Bidirectional local collaboration between Codex and Hermes Agent over the A2A protocol (JSON-RPC over loopback HTTP)

Open framework for simulating compatibility between agents — twin pairing, stress scenarios, no single match score

Portable contracts, verification hooks, and transports for evidence exchange between independent DreamNet organisms.

The distributed Agentic Post Office - .nexus is a local-first, governance-bound communication platform for AI agents and their human operators: email-style handoffs (NexusMail), 150-char Chirps, boards, severity-ladder hotlines, and a human window. MCP-native, harness-agnostic, append-only.

Portable, non-authorizing agent blueprint and deployment manifest protocol — Elixir reference implementation, conformance corpus, and second-language verifier.
