The Right Tool for Code Mode: a BEAM-native Lisp sandbox for MCP tools
Hi there
I’ve been working on ptc_runner MCP - a standalone MCP server that aggregates upstream MCP tools and exposes them via a Clojure like REPL as code mode.
The post is about why I think code mode should use a small purpose built language for short lived untrusted programs instead of using Python or Javascript.
Btw, what’s your thoughts on instead of using MCP you use code mode and upstream REST/HATEOAS styled HTTP endpoints ?
