Our reading of Register, from the data
Register is an MCP server from forestrie, 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 in the last day (2026-10-17).
It runs locally on your machine over stdio and needs 2 secrets (FORESTRIE_GRANT, FORESTRIE_AUTHORITY_GRANT); use a scoped, least-privilege key.
