CAUTION· not started

Publisher claims: "The exoskeleton for your AI coding agent: memory across sessions, a live code map, undo for every change and a hallucination check. MCP server for Claude Code, Cursor, Codex, Gemini CLI." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
IMPERAL_TOKENConfiguration, not credentials: IMPERAL_API_URL, IMPERAL_MCP_EXTRA_ROOTS, IMPERAL_MCP_IGNORE, IMPERAL_MCP_LAUNCHER, IMPERAL_MCP_SPOOL, IMPERAL_PANEL_URL, IMPERAL_WORKSPACE
Where it talks to
imperal.io (its own)Also astral.sh — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names astral.sh as well as its own vendor. The guard injects IMPERAL_TOKEN only into requests to imperal.io (and its subdomains) and refuses the rest.

$vet-skills run --secrets IMPERAL_TOKEN=imperal.io -- uvx imperal-mcp

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-13 and scored it 68/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Access to sensitive file paths; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
