i love seeing experiments that make this stuff run locally… bridging an MCP client into a Deno sandbox feels like a natural step if you want the same ergonomics offline.

ALSO there's a bunch of interesting questions around security and permission models when code is pulled on demand. Running arbitrary tools in a sandbox is neat, BUT you still need to think about what those tools can access… environment variables, network, local file system… limiting that scope could make these experiments more viable for larger teams.

i'd be curious to see benchmarks for cold starts and memory usage in this model… as well as patterns for caching compiled tools so they aren't reloaded every time. Discovering tools on demand is one thing, making them feel instantaneous is another. HOWEVER it's exciting to see folks pushing on this area and sharing their work.
