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…

Detection tooling blocked those patterns in testing; some public evals moved offline or were rebuilt…

Install from github.com/NVlabs/SoL Pi ; every mechanism defaults off until you enable it in sol pi.json…
