What the code does

We read the source, 22 h ago · rules 3dff92dd89df

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.

Claims read-only, but the code runs commands branding/build.py:122

    subprocess.run(

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/mcpserver/archive.go:153, internal/mcpserver/record.go:238, internal/sink/sink.go:228

            candidate = filepath.Join(root.real, candidate)

Runs an external command branding/build.py:122

    subprocess.run(

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

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 mail-muncher and you get told the day something new turns up.

mail-muncher — questions

Answers built from our own checks of this server.

Why is there no uptime for mail-muncher?

mail-muncher runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.

Is mail-muncher open source?

Yes — it is published under the MIT licence, written in Go and 3 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
