Common questions
Is vet402 safe?
It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 14 days ago, and the latest version (1.0.1) reached the registry 4 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.
What can I use instead?
In the same category: World Monitor, Claude Flow, Tldraw

vet402
A Cursor and Claude Code plugin that connects agents to the hosted vet402 MCP server.
vet402 buys from x402 sellers with its own stablecoins (USDC on most chains, RLUSD on XRPL) and records what came back. Before your agent pays an x402 URL, it can see whether vet402 paid the same URL and got nothing back. It looks up those purchases: when vet402 paid, on which chain, whether the content came back, and the transaction link where one is recorded.
Install
Cursor: add the MCP server below to .cursor/mcp.json. Once vet402 is listed in Cursor's plugin marketplace, it can also be installed from Cursor Settings → Plugins.
Claude Code:
/plugin marketplace add kzmttkc/vet402-plugin/plugin install vet402@vet402
Or add only the MCP server: claude mcp add --transport http vet402 https://vet402.com/mcp
MCP
{"mcpServers": { "vet402": { "type": "http", "url": "https://vet402.com/mcp" } } }
No auth. The server is read-only and free. It is rate-limited per client IP.
Tools
| Tool | For | What it returns |
|---|---|---|
check_x402_seller | Agents about to pay | What happened when vet402 paid this URL in the last 30 days, the last five purchases, and verified_terms (see below) |
check_my_x402_endpoint | x402 sellers | Which catalogs list your endpoint, how many paid purchases delivered, the failure modes vet402 recorded and when vet402 can buy again |
find_x402_sellers | Agents looking for an API | Listings matching a query where vet402 paid and received content in the last 30 days, plus untested listings vet402 has not paid yet |
check_x402_seller returns 30-day delivered and settled_not_delivered counts. Each of the last five purchases has a transaction link where one exists. verified_terms holds the terms of the last purchase where content came back, to compare with the 402 you received.
The hosted server is the source of truth for tool names and schemas. Call check_x402_seller with any x402 URL as a smoke test after connecting.
