Vercel Labs’ fx: Zig coding agent that lists which MCP features it skips

Kin Lane covers Vercel Labs’ experimental Apache-2.0 fx agent (Zig, ~6MB, v0.0.13 on github.com/vercel-labs/fx): it documents MCP transports and supported features, then states what it skips—Tasks, Apps, Skills over MCP, Client Credentials, Enterprise-Managed Authorization, registry install, and acting as an MCP server. Default mode auto-runs routine local work but routes every MCP tool call through a review model first.
