thanks for explaining, especially the runtimes part!

i am currently running Docker MCP Containers + MCP Gateway mixed with Remote MCPs in microVMs (aka. Sandboxes).

seems to be the most portable setup, so you don't have to worry about dealing with different exec like uvx, poetry, bun, npx and the whole stdio/streamable http conversion.

lambdas sound interesting, esp. if you have figured out the way to make stateful work stateless, but comes with the downside that you have to maintain all the integrations yourself + the environment itself might have compatibility issues. i've seen someone also using cloudflare dynamic workers for similar use-case (disco.dev), but they're maintaining all the integrations by hand (or with Claude Code rather). more extreme version of this would be writing custom integration specific to the user by following very strict prompt.

anyways, i'll look into Metorial as am curious about how the portable runtimes work.

i am also maintaining a list of MCP gateways, just added you there as well: https://github.com/e2b-dev/awesome-mcp-gateways

thanks for building this, looking forward to checking it out!
