Nothing serious here today

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

This one needs environment variables set before it will start: PAY_WALLET_KEY (Optional. Private key of a funded Circle Gateway wallet, for the paid tools. Free tools need nothing.), PAY_CHAIN (Optional. Where that wallet holds USDC: arc, base, arbitrum or hyperEvm. Default arc.), PAY_MAX_USDC_PER_CALL (Optional. The most one call may cost before the tool refuses to pay. Default 0.05.). The author declared them in the registry entry; get the values from the project itself.

Arc Treasury — questions

Answers built from our own checks of this server.

Why is there no uptime for Arc Treasury?

Arc Treasury runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package arc-treasury-mcp was installed 333 times last week.

How do I connect Arc Treasury?

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 runs locally, so the command pulls arc-treasury-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Arc Treasury?

The npm package arc-treasury-mcp was installed 333 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
