agent-protocols

Contract lab for agent protocol envelopes - versioned MCP/A2A message contracts, envelope validation, and compatibility diffs (compatible/forward/breaking). Python 3 stdlib + optional .NET 9 runtime.

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

A curated directory of AI agent infrastructure projects: runtimes, sandboxes, memory, identity, observability, workflows, and protocols.

⚡️ Answer the accountability question about your organization in ninety seconds: seven questions, three files at well-known paths, and a URL you can paste into a vendor questionnaire. Not released yet.

A protocol specification and lightweight frontend runtime for AI agent-driven interfaces. Three commands, one JSON stream, zero backend dependencies.

meshcognition.org — the cognitive substrate beneath the agentic mesh. Mesh intelligence on an open protocol: the Mesh Memory Protocol (MMP). Pioneered by SYM.BOT.

Awesome Agent SDLC v1.2 — Open-source standard documentation repository for AI-agent-assisted software development: agent roles, the A2A handoff protocol, the JUDGE verification layer, a maturity model, and multi-AI-tool (Cursor, Gemini, Claude, Copilot) configurations. Licensed AGPL-3.0.

A minimal contract for two AI coding agents working the same repo — git as the message bus, human owner at the gates

A curated, layer-by-layer guide to protocols and standards for integrating LLM agents, with practical trade-off comparisons.

Bilingual, source-grounded observatory tracing global AI from its intellectual and computational roots to the agentic frontier across models, protocols, runtimes, evaluation, safety, governance, and ecosystems.

Awesome list of open-source AI agent identity, trust, governance, security, and naming projects. Protocols, standards, tools for agent verification, permissions, attestation, reputation, and policy enforcement.

Two companion A2A extension specifications: the Agent Transparency Profile (signed per-answer disclosures) and the Agent Dialog Profile (binding verification dialog between agents)

Agents, Orchestrated. Real builds on the agentic stack, one layer per episode. Autonomy is table stakes; the moat is everything around the agent.

4-tier agentic supply-chain testbed (beer game) for benchmarking agents.

A2A protocol hub — registers agents, routes messages between them, and serves a unified agent card for discovery

⛏️ evidence-traced agent protocols for rediscovering overlooked research — autopsies for sleeping-beauty papers, any harness

ANP2 is an open, permissionless AI-to-AI communication network and protocol at anp2.com: a signature-only relay where any agent with an Ed25519 keypair publishes signed events to a public append-only log, declares machine-readable capabilities, votes trust into a weighted graph, and runs a five-stage task lifecycle (request, accept, result…

EP 03 of Agents, Orchestrated. A shopping agent with an ES256-signed $7,000 spending mandate, and the three times it gets refused. AP2 + Camunda 8, fully runnable.

Workflow docs, Birdseye/Codemap, Task Seeds, acceptance operations, reusable CI, context engineering, and plugin-based evidence tracking

EP 02 of Agents, Orchestrated. Agents that stream the interface, not text. AG-UI + Camunda 8 wealth onboarding, runnable without API keys.
