- npm downloads/week: 16 (2026-10-19)

No known vulnerabilities in OSV for 1.0.1 (checked 2026-10-23)
npm facts come from the public npm registry (registry.npmjs.org, api.npmjs.org). Each figure is the registry's own and is never added to another. A registry that publishes no figure shows none: no number is not zero. Vulnerability records come from OSV.dev (CC BY 4.0) and concern the declared version only; a listing that declares no version gets no answer. We do not scan code.
Works with

Built from what Official MCP Registry declares.
claude mcp add --env "PAY_WALLET_KEY=<YOUR_PAY_WALLET_KEY>" --transport stdio arc-treasury-mcp -- npx -y arc-treasury-mcp[mcp_servers.arc-treasury-mcp]
command = "npx"
args = ["-y", "arc-treasury-mcp"]
[mcp_servers.arc-treasury-mcp.env]
PAY_WALLET_KEY = "<YOUR_PAY_WALLET_KEY>"{
"mcpServers": {
"arc-treasury-mcp": {
"command": "npx",
"args": [
"-y",
"arc-treasury-mcp"
],
"env": {
"PAY_WALLET_KEY": "<YOUR_PAY_WALLET_KEY>"
}
}
}
}Replace the values in angle brackets with your own. We show the names of the settings, never values.
Optional settings it also lists: PAY_CHAIN, PAY_MAX_USDC_PER_CALL.

Want this mark on your plugin in our catalog?
Prove you maintain it with a file in its repository, a file on your domain or a DNS record, and you can show this mark on the card, with live banners for your site and README. How verification works
You also get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.
Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
