ARP runs on your own machine — the client starts it, so there is no endpoint to ping. 370 installs a week from npm. Last commit 10 Nov 2026.
Check a skill, MCP server or agent before your agent installs or pays it. Reads only.
Today is the operative word: we check ARP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Put your own values in place of
<ARP_TARGET> (The chain ARP reads: testnet (Intuition testnet 13579) until the tester round ends), <ARP_TOOLS> (The tool set: read serves the public reads only, holds no key and signs nothing).
