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.

File ships in the package but is absent from the source [пакет] figma-plugin/code.js:1
этот файл ставится пользователю, но в репозитории его нет
  const child = spawn(opts.chromePath, flags, { stdio: ["ignore", "pipe", "pipe"] });

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.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: FIGMA_TOKEN (Figma personal access token (read-only). Only needed for the REST path — not required when the Plumb plugin is paired in Figma desktop. Create one at figma.com → Settings → Security → Personal access tokens.), PLUMB_SESSION_NAME (Optional label shown in the Plumb Figma plugin when multiple plumb-mcp servers are paired with the same plugin (multi-agent connect). Defaults to the basename of the current working directory.). The author declared them in the registry entry; get the values from the project itself.

Plumb MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Plumb MCP?
Plumb MCP 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 plumb-mcp was installed 116 times last week.
How do I connect Plumb MCP?
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 plumb-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Plumb MCP?
The npm package plumb-mcp was installed 116 times in the last week. Week over week that is -70%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Plumb MCP open source?
Yes — it is published under the MIT licence, written in TypeScript, 82 stars on GitHub and 3 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
