Available tools 4

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

agent

check_agent_readiness

Free check of whether AI agents can use a business's website: can they get in, understand it, act on it (API, MCP) and trust it. Returns a 0–100 score, a verdict, and each check with what was found and how to fix it.

payability

check_payability

Free. Check whether an x402 endpoint or MCP tool is real, payable and active BEFORE you pay it. Pass a URL; get a 0–100 payability score, the listed price and networks, when the catalog last saw it active, how many of the last 30 days its payment address was paid, on-chain USDC payments and distinct paying wallets on Base over 30 days (with a one-wallet wash warning), a live check that it really answers 402 and asks to be paid at its listed address (x402 version, CAIP-2 networks), and flags for catalog-flooding or outlier pricing. Scored from the public PayAI x402 Bazaar + MCP Registry index — listings are third-party data, not endorsed. Returns a 0–100 score, a verdict (payable / mixed / unverified), the listed price, networks and last-active date, plain-language signals, and provider flooding / price-outlier warnings.

report

report_unmet_need

Free. Nothing fits? Say what you needed (free, no personal information): the report_unmet_need MCP tool, or POST https://subpay.ai/api/v1/find/unmet. It decides what gets built next.

tools

find_tools

Free. Free search across public agent-tool catalogs — paid x402 APIs and MCP tools (PayAI's x402 Bazaar) and MCP servers (the official MCP Registry). Describe what you need in plain words; get matching tools with price, payment networks and how to call them. Returns up to 10 matches with kind (x402-http, x402-mcp, mcp-remote, mcp-package), URL, price per call in USD when listed, payment networks, and a one-line howToUse. `matched: false` means nothing covered your request well.

Agent Tool Finder — questions

Answers built from our own checks of this server.

What can Agent Tool Finder do?

It exposes 4 tools, read directly from the server on our last check. Among them: check_agent_readiness, check_payability, find_tools, report_unmet_need. 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 Agent Tool Finder working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 10 of 92 checks got a reply (10.9%), average response time 316 ms. The bar chart above shows every period we have measured.

The registry lists Agent Tool Finder as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Agent Tool Finder?

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 Agent Tool Finder need an API key?

No. Agent Tool Finder completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Agent Tool Finder?

It answers our handshake in 316 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
