Our reading of ARC-1, from the data
ARC-1 is an MCP server from arc-mcp, listed in the official MCP Registry.
We haven't measured its tool list yet, so its token cost is unknown.
Maintenance is active: the last public signal was 2 days ago (2026-10-19).
It runs locally on your machine over stdio and needs one secret (SAP_PASSWORD); use a scoped, least-privilege key.
