agent-client-protocol-polyfill
Polyfill proxies for backward compatibility with agents that don't support newer ACP features natively.
MCP-over-ACP Polyfill
The [mcp_over_acp] module provides a proxy that bridges MCP-over-ACP transport
for agents that don't support mcpCapabilities.acp. It intercepts NewSessionRequest
to transform McpServer::Http entries with acp: URLs into localhost TCP bridges,
and handles _mcp/* messages by routing them through those bridges.
