Official JavaScript SDK for the Agent2Agent (A2A) Protocol

A JavaScript library that helps run agentic applications as A2AServers following the Agent2Agent (A2A) Protocol. You can install the A2A SDK using . If you plan to use the Express integration (imports from ) for A2A server, you'll also need to install Express as it's a peer dependency: If you plan to use the GRPC transport (imports from or ), you must install the required peer dependencies: You…

Verification confirms publisher identity (repo ownership), not code safety. The security scan covers known CVEs and suspicious install scripts.

Read out of the source npm actually ships, at scan time. The package was never executed. Tools registered dynamically at runtime, or hidden inside bundled or minified code, can be missed — so this is a floor on the tool surface, not a complete census of it.

No dependency coverage

This entry publishes no npm package, so Forge has no dependency tree for it. That is a gap in coverage — not a statement that it has no dependencies.
