naver-works-mcp@r1
VERIFIED· install onlyPublisher claims: "Enables Claude to work with a corporate mailbox over IMAP/SMTP — listing, searching, reading, sending, forwarding, replying, handling attachments, and moving messages between folders — alongside calendar browsing and event creation/editing over CalDAV. Authentication needs only a single external app password, with no developer-console registration or admin approval." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Nothing executable in the bundle ran; the trace covers the install step only.- Tested
- every file read, file written and host contacted by what ran
- Not tested
- use of the skill by an agent
What this means for the label: Verified 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
NAVER_APP_PASSWORDConfiguration, not credentials: ATTACHMENT_DIR, DELETE_ALLOWED_DIRS, NAVER_CALDAV_SERVER, NAVER_EMAIL, TRASH_FOLDER- Where it talks to
- no vendor host named in the codeAlso worksmobile.com — 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
- use of the skill by an agent
Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names worksmobile.com as well as its own vendor. The guard injects NAVER_APP_PASSWORD only into requests to the host you bind (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.
Is naver-works-mcp@r1 safe to install?
KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-13 and scored it 86/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
