a2a-client is an MCP server that provides security-hardened access to Agent2Agent (A2A) agents through the official SDK, exposing tools for discovering agent cards, sending/streaming messages, and managing tasks with operator confirmation gates. Every remote agent card is treated as untrusted input with strict validation, SSRF protection, credential isolation, and confirmation-gated task cancellation.
