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.

Builds a file path from a variable internal/embedder/download.go:38
        path := filepath.Join(modelDir, filename)

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.

Devrag — questions

Answers built from our own checks of this server.

Why is there no uptime for Devrag?
Devrag runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is Devrag open source?
We cannot say either way: written in Go and 63 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
