How can I check what an MCP server or npm package can do with my keys before I install it?

Paste the package, MCP endpoint or install command into Sato Check (/check) or call onchain_agent_check_install; it reports key access, key egress and fund actions, as of 2026-10-29.

What does an MCP server do with my wallet key?

Answered from live data2026-10-29

Every reading Sato Hub holds for Zerion, with the field it came from. These are the same checks /preflight runs live against a package name — nothing here describes the package's behaviour once it runs.

Check	Reading	Where it comes from
Documented install	npm install zerion-cli	the project's own deploy spec on its Sato Hub record
Install reproduced by Sato Hub	yes, 2026-10-26	container run of that install line
Latest commit or release	2026-10-13	the later of the last commit and last release
Liveness label	Active	derived from that commit or release date
Source availability	Partial	declared licence and repository
Sato Score	85 (High)	openness, activity, verifiability
Verification status	Self-Reported	self-reported unless an earned check is named
What Sato Hub has NOT done	no security review, no dependency audit, no runtime analysis	stated so it is never inferred

How this was answeredShowHide

Every reading on the "zerion" record — the documented install line, whether Sato Hub reproduced it in a container, activity, openness and score — laid out as the checks lib/preflight.ts runs live. It names what was NOT done as explicitly as what was.

Every answer on this page is produced by one named function over Sato Hub's live records on the date shown. Nothing is typed by hand, no figure is carried over from a previous day, and an answer with nothing behind it says unknown rather than zero. The Sato Score measures how open, active and verifiable a project is — it is not a safety, quality or returns grade.
