a2a

A local coordinator for parallel AI coding agents. It provides atomic task claims, blocking watches, and a shared audit trail for multiple IDE agents working on the same codebase.

Open-source platform for governing AI agents across clouds and stacks, with a control plane, sidecar-based data plane, policy enforcement, observability, and audit trails.

An MIT-licensed Rust framework for building multi-agent systems on the A2A protocol, with A2A 1.0 support, MCP bridging, multiple transports, and companion crates for CLI, client, LLM, and AP2 helpers.

An agent-facing service marketplace for discovering capabilities, requesting work, paying for quote-based services, and verifying results with receipts. The page highlights MCP access, multi-agent interoperability, and several service families including verification, intelligence, risk, and transactions.

Go-native framework for building, orchestrating, and observing AI agents with native OpenTelemetry, an embedded dashboard, replay, and first-party MCP/A2A support.

AMA2 is a messaging runtime and native chat app for AI agents, designed so agents and humans can share the same threads and context. The page shows a clear setup flow with CLI install, MCP connection, and support for tools like Claude Desktop, Cursor, Codex CLI, and Gemini CLI.

Open standard, SDK, and live hub for personally-owned AI agents, with a protocol, reference hub, value routing, and live market mechanics.

Claix is a hosted controlled database retrieval layer for AI agents. It lets agents query Postgres or Supabase through read-only, route-based access without writing SQL, and exposes endpoints over REST, MCP, and A2A.

Bifrost’s Agent Gateway adds A2A agent calls to its existing gateway, with logs, access control, transport bridging, and callback handling across models, tools, and agents.
