Some of the best MCP tools today only run locally via STDIO. That works fine for desktop apps, but it’s a real limitation when you want to automate them or plug them into agent workflows.

We ran into this and built a way to host STDIO-based MCP tools in the cloud with zero code changes. It uses Streamable HTTP and supports token-based authentication (either bearer or inline in the URL). We also kept it simple by using the same config file format as Claude Desktop so you can plug in tools without rewriting anything. It support npx, uvx, pipx, and python.

Originally built it for a client who needed remote automation, but figured others might be facing the same problem.

Curious if others here have run into this problem or built something similar.
