What the code does

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Sounio Compiler and you get told the day something new turns up.

Sounio Compiler — questions

Answers built from our own checks of this server.

Why is there no uptime for Sounio Compiler?
Sounio Compiler runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package sounio-mcp-server was installed 45 times last week.
How do I connect Sounio Compiler?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls sounio-mcp-server straight from pypi; nothing to host, nothing to sign up for.
How many people use Sounio Compiler?
The pypi package sounio-mcp-server was installed 45 times in the last week. Week over week that is -10%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Sounio Compiler open source?
Yes — it is published under the Apache-2.0 licence, written in Lean, 6 stars on GitHub and 84 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
