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.

Builds a database query by concatenation watch/index.js:298

POST ${o}/w/<token>/cancel delete
GET  ${o}/w/<token>/upgrade

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.

x402

x402_audit_merchant

Full paid due-diligence audit of an x402 merchant: live probe, price-drift detection between advertised and actual challenge price, settlement history, unique buyer count, and on-chain verification that USDC actually reaches the payTo address. Returns PASS/CAUTION/AVOID with evidence. Costs $0.01 USDC via x402 — returns payment instructions if called without payment.

x402_check_endpoint

Check whether an x402 endpoint is alive and emits a valid HTTP 402 payment challenge, before you pay it. Free liveness check. Returns reachability, status code and whether a valid challenge was found.

x402_facilitator_guide

Which x402 facilitators actually settle payments, measured by probing each with a real signed EIP-3009 payload. Tells you which are keyless, which need API keys, which are testnet-only and which are unreachable. Free. Use before choosing a facilitator.

x402_gas_price

Current gas price and estimated simple-transfer cost for an EVM chain. Free preview route. Supports base, polygon, arbitrum, optimism, ethereum.

x402_market_stats

Get measured statistics about the x402 ecosystem economy: total 30-day revenue across sampled resources, revenue concentration, revenue at a given rank, price distribution and payer concentration. Free. Use this to decide whether building or buying on x402 is worth it.

x402_verified_merchants

List x402 merchants that have been VERIFIED to accept payment — each one actually paid with real USDC on Base, with the settlement transaction hash. This is different from a liveness probe: public censuses only check whether a 402 is emitted, not whether paying works. Use this to find endpoints that will actually serve you. Free.

x402 economy tools — questions

Answers built from our own checks of this server.

What can x402 economy tools do?

It exposes 6 tools, read directly from the server on our last check. Among them: x402_audit_merchant, x402_check_endpoint, x402_facilitator_guide, x402_gas_price, x402_market_stats, x402_verified_merchants. 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 x402 economy tools 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 104 ms. The bar chart above shows every period we have measured.

How do I connect x402 economy tools?

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 x402 economy tools need an API key?

No. x402 economy tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is x402 economy tools?

It answers our handshake in 104 ms on average, which is faster than 93% 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 x402 economy tools open source?

We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
