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.

Runs an external command video/assemble.py:64
    result = subprocess.run(command, capture_output=True, text=True)
Builds a database query by concatenation index.html:477
            const untilNextUpdate = hourlyUpdatedAt.getTime() + HOUR_MS + AFTER_UPDATE_MS - Date.now();

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.

Currensor — questions

Answers built from our own checks of this server.

What can Currensor do?
It exposes 1 tools, read directly from the server on our last check. Among them: convert_currency. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Currensor 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 109 ms. The bar chart above shows every period we have measured.
How do I connect Currensor?
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.
Does Currensor need an API key?
No. Currensor completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Currensor?
It answers our handshake in 109 ms on average, which is faster than 90% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Currensor open source?
The code is open source: it is published under the MIT licence, written in HTML and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at currensor-mcp.currensor-mcp.workers.dev, which runs on its operator's own terms.
