Nothing serious here today

Today is the operative word: we check Petra402 every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

scrape

scrape

Fetch a public web page and return its main content as markdown. Charged per successful call with x402: 0.005 USDC on Base Sepolia (testnet). A failed scrape is never charged, and a cache hit inside 24 h is free. Payment happens at the HTTP transport layer: an unpaid call answers 402 with the payment requirements; sign and repeat the identical JSON-RPC call with the payment header. This server speaks x402 v2 (PAYMENT-SIGNATURE / PAYMENT-RESPONSE), not v1 (X-PAYMENT). A v1 client will loop on 402 without ever settling. Refusals that are policy and never charged: government, military and any health-related domain; private or internal addresses; paths disallowed by robots.txt; sites protected by an anti-bot vendor (never bypassed).

Petra402 — questions

Answers built from our own checks of this server.

What can Petra402 do?

It exposes 1 tools, read directly from the server on our last check. Among them: scrape. 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 Petra402 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 191 ms. The bar chart above shows every period we have measured.

How do I connect Petra402?

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.

Does Petra402 need an API key?

No. Petra402 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 Petra402?

It answers our handshake in 191 ms on average, which is faster than 68% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Petra402 open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
