Supports stdio, streamable-http, and SSE transports.

Adds an optional governance plane — Ed25519 agent identities, per-agent spend/rate budgets, and a hash-chained tamper-evident audit trail enforced in the call path. Also runs as a drop-in MCP server. Python, Apache 2.0.

Ships a dedicated `ai-mocks-a2a` module with a `MockAgentServer`, full A2A protocol coverage (11 endpoints), real Server-Sent Events streaming, plus shared mocks for OpenAI/Anthropic/Gemini/Ollama — useful for service virtualization, contract tests, and offline development. MIT licensed and published on Maven Central.

Add any A2A-compatible agent by URL, fetch its AgentCard, run multi-turn chat sessions with `Context` and `Tasks`, render markdown-supported `Messages`/`Artifacts`, and visualize streaming responses and tool-call traces — effectively an early "web browser" for A2A agents. Apache 2.0.
