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 .agents/plugins/hybrids3/bin/cli.js:40
const result = spawnSync(process.execPath, args, { stdio: "inherit" });

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.

HybridS3 — questions

Answers built from our own checks of this server.

Why is there no uptime for HybridS3?
HybridS3 runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is HybridS3 open source?
No, and the distinction matters: its licence is declared as WTFPL. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
