What the code does

We read the source, 46 min ago · tools taken from the live server · rules 995398eba69f

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 lib/credits.js:113
      const r = Number(await need().eval(TAKE, { keys: [k(hash)], arguments: [String(n)] }));
      const target = path.join(dir, name);
Runs an external command media/explainer/build.py:29
    subprocess.run(cmd, check=True)
Touches key and credential files lib/jev-poison.js:28
  String.raw`\b(read|open|cat|include)\b.{0,30}(~\/|\.ssh|id_rsa|\.env\b|mcp\.json|private key|seed phrase|mnemonic)`,
      $("who").innerHTML = account.toLowerCase() === AUTHORITY.toLowerCase()

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.

Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

x402
x402_buy
Paid ($0.02 via x402 in USDC on Base, Solana, Algorand or Stellar, or RLUSD on the XRP Ledger, inside the call): say what your agent needs ("weather forecast for Amsterdam tomorrow", "BTC price", "EUR to USD rate") and Fizzl buys the right paid x402 API, the one x402 Doctor has seen paying out day after day at a fair price (up to $0.01), fills in its input, pays it from its own wallet and returns the answer, checked by TypeSafe Jev, with which service it came from and a signed receipt. Nothing is charged when no seller delivers. To see first what it would buy, call x402_pick (free).
x402_pick
Free: say what your agent needs and get the paid x402 API that x402 Doctor has seen paying out day after day at a fair price (up to $0.01), with its track record, price and example input, plus alternatives. To buy it in one call, POST https://buy.fizzl.eu/v1/buy {"need": …} ($0.02 over x402): the answer comes back checked, and nothing is charged when no service delivers. Limited to 10 free calls an hour.

Fizzl Buy — questions

Answers built from our own checks of this server.

What can Fizzl Buy do?
It exposes 2 tools, read directly from the server on our last check. Among them: x402_buy, x402_pick. 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 Fizzl Buy 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 513 ms. The bar chart above shows every period we have measured.
How do I connect Fizzl Buy?
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 Fizzl Buy need an API key?
No. Fizzl Buy completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Fizzl Buy?
It answers our handshake in 513 ms on average, which is faster than 26% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Fizzl Buy open source?
The code is open source: it is published under the AGPL-3.0 licence, written in JavaScript, 1 stars on GitHub and 2 open issues. The licence covers the code in the repository, not the hosted service at buy.fizzl.eu, which runs on its operator's own terms.
