What the code does

We read the source, 21 h ago · rules 3dff92dd89df

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 a command on install [пакет] package.json:1

postinstall: node scripts/postinstall.js

File ships in the package but is absent from the source [пакет] bin/osc-bridge.js:1

этот файл ставится пользователю, но в репозитории его нет

Runs an external command npm/bin/osc-bridge.js:27, [пакет] bin/osc-bridge.js:27

const res = spawnSync(bin, process.argv.slice(2), { 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.

osc-bridge — questions

Answers built from our own checks of this server.

Why is there no uptime for osc-bridge?

osc-bridge 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 npm package @roomi-fields/osc-bridge was installed 37 times last week.

How do I connect osc-bridge?

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 @roomi-fields/osc-bridge straight from npm; nothing to host, nothing to sign up for.

How many people use osc-bridge?

The npm package @roomi-fields/osc-bridge was installed 37 times in the last week. Week over week that is +25%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is osc-bridge open source?

We cannot say either way: written in Rust and 7 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
