MCP React Toolkit runs on your own machine — the client starts it, so there is no endpoint to ping. 106 installs a week from npm. Last commit 1 Oct 2026.
9 MCP servers for React/TypeScript — dep auditing, a11y, test gen, and TypeScript enforcement.
What the code does
We read the source, 4 d ago · rules 995398eba69f
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 entry = path.join(ROOT, "tools", requested, "build", "index.js");
const output = execSync(cmd, {
return { result: before + (change.insert || '') + after, applied: true };
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.
