What the code does

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.

Runs an external command llm-tests/cli_mcp_server.py:45
        completed = subprocess.run(
            try { System.Diagnostics.Process.Start(new System.Diagnostics.ProcessStartInfo(githubUrl) { UseShellExecute = true }); }
Builds a file path from a variable gh-pages/hooks.py:208
        resolved = posixpath.normpath(posixpath.join(source_dir, target))

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
