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.

Executes code built at runtime src/services/rate-limit.service.ts:78
  const result = (await r.eval(
Sends data to a third-party sink src/adapters/telegram/index.ts:10
      baseUrl: `https://api.telegram.org/bot${token}`,
    content.innerHTML = html;

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.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Apibase — questions

Answers built from our own checks of this server.

Why is there no tool list for Apibase?
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 Apibase working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 797 ms. The bar chart above shows every period we have measured.
How do I connect Apibase?
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 is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.
Does Apibase need an API key?
Yes. Every time we knock, Apibase answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Apibase?
It answers our handshake in 797 ms on average, which is faster than 14% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Apibase?
The npm package apibase-mcp-client was installed 103 times in the last week. Week over week that is +55%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Apibase open source?
Yes — it is published under the MIT licence, written in TypeScript, 10 stars on GitHub and 172 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
