Rebase MCP Server

What the code does

We read the source, 3 d ago · rules 995398eba69f

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.

        const before = new Set(Object.keys(process.env));

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.

        const child = spawn(binary, [...execArgs, "rebase", ...commandArgs], {

import { existsSync, readFileSync, readdirSync, writeFileSync, mkdirSync, chmodSync } from "node:fs";

        const before = new Set(Object.keys(process.env));

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

    const srcDir = path.join(SEED_ASSETS_DIR, assetSubdir);

            const text = r < o.drop ? null : r < o.drop + o.mishear ? WRONG[Math.floor(rnd() * WRONG.length)] : word;

COPY package.json pnpm-lock.yaml pnpm-workspace.yaml .npmrc ./

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.

Optional settings from the registry entry, left out of the block above: REBASE_PROJECT_DIR (Project root — the directory holding rebase.json. Defaults to the working directory), REBASE_BASE_URL (Backend URL, used when no local dev server is discovered), REBASE_API_TOKEN (API token for the target project. Not needed against a local dev server), REBASE_MCP_ALLOW_REMOTE_WRITES (Allow destructive tools to run against a non-local target. Off by default).
