#a2a

An orchestration DSL and embedded runtime for hosting agentic systems. Durable, inspectable workflows with deterministic step ordering, running in-process under a capability jail — the model lives in your host, not in the runtime. 30+ companion packages for memory, transport and governance.

Elixir implementation of the Agent-to-Agent (A2A) protocol (https://a2a-protocol.org).

The .NET library to build AI agents with 30+ built-in connectors.

540 security tests for AI agent systems — MCP, A2A, x402/L402, decision governance, benchmark integrity, skill supply chain. AIUC-1 pre-cert, NIST AI 800-2 aligned, MCP tool-poisoning reproduction. v4.9.1

Ruby's capable AI runtime

MCP Fusion - The TypeScript framework for secure MCP servers.

AI agents in Go — Temporal for durable, crash-resilient execution or run in-process with zero setup. OpenAI, Anthropic, Gemini, Deepseek, Ollama, tools, MCP, A2A, RAG, memory, conversations, AG-UI, streaming, sub-agents & human-in-the-loop.

An Agent Development Kit (ADK) allowing for seamless creation of A2A-compatible agents written in Go.

A2A agent server that provides Context7-style documentation capabilities for your agents

Type-safe, async Rust SDK for the Agent2Agent (A2A) protocol, built to the final v1.0.0 spec — JSON-RPC, REST, WebSocket & gRPC for building interoperable AI agents

Declarative YAML framework to define, run & orchestrate AI coding agents

A2A agent server specialized in generating and automating n8n workflows

A science agent supporting any general AI agent in performing data management operations at scale. Builds upon the heritage of the IOWarp platform and proudly represents work done at Gnosis Research Center at Illinois Tech. Supported by NSF.

Make AI agents follow instructions reliably and prove what they did. State machine engine with evidence chains, multi-agent delegation, human gates, and auditable execution — via MCP or CLI.

One agent SDK, hand-ported to 7 languages — JavaScript, Python, Go, Java, C#, Elixir, Clojure — every port held to the same spec by a CI-enforced cross-port conformance suite, all seven at full tier. MCP · skills · native · HTTP · built-in · A2A tools behind one interface. Docs: https://muthuishere.github.io/toolnexus/

Parley — a transport-agnostic MCP seam for messages, context sharing, and task hand-off between humans, chat bots, and coding agents. Runs on local SQLite, Redis, Matrix, XMPP, or NATS.
