What the code does

We read the source, 21 h ago · rules 995398eba69f

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

A tool parameter reaches a dangerous call read_multiple_files.paths → packages/runtime/src/tools/files.mjs:1827, read_multiple_files.paths → packages/runtime/src/tools/files.mjs:1832, extract_archive.archive → packages/runtime/src/tools/files.mjs:1890 и ещё 20
       const result = spawnSync(tools.zip, ['-r', '-q', '-y', staging, '--', ...archiveNames], { cwd: snapshotRoot, encoding: 'utf8', timeout: 120_000, maxBuffer: 16 * 1024 * 1024 });
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.

Checks whether it runs in a sandbox packages/client/src/agent-update.mjs:213
export function supervisorRestart({ platform = process.platform, dockerenv = existsSync('/.dockerenv'), parentOurs = parentIsServiceManager() } = {}) {
  const result = spawnSync(npm.command, [...npm.args, 'root', '--global'], { encoding: 'utf8', windowsHide: true });
        const handle = await open(path.join(current, part), constants.O_RDONLY | constants.O_DIRECTORY | constants.O_NOFOLLOW);
Executes code built at runtime packages/client/src/agent-update-rollout.mjs:63
  return Number(await command.eval(script, { keys:[key], arguments:[String(limitPerMinute)] })) === 1;

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

A tool parameter here reaches a dangerous call

That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

ReMCP — questions

Answers built from our own checks of this server.

Why is there no tool list for ReMCP?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is ReMCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 209 ms. The bar chart above shows every period we have measured.
How do I connect ReMCP?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to ReMCP?
No API key is involved. ReMCP answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is ReMCP?
It answers our handshake in 209 ms on average, which is faster than 69% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is ReMCP open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 4 stars on GitHub. The licence covers the code in the repository, not the hosted service at remcp.site, which runs on its operator's own terms.
