mainframe-mcp-server@3.0.0

VERIFIED· install only

Publisher claims: "Enables MCP-compatible AI agents to access IBM z/OS jobs, datasets, USS files, and operational diagnostics through the Zowe SDK, with structured tool outputs and guardrails for mainframe operations." 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.

Where it talks to
no vendor host named in the codeAlso service-now.com, atlassian.net, pagerduty.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 service-now.com, atlassian.net, pagerduty.com as well as its own vendor. The guard injects INCIDENT_TOKEN, MQ_REST_PASSWORD, SECURITY_AUDIT_SPLUNK_TOKEN, SECURITY_AUDIT_WEBHOOK_TOKEN, SECURITY_AUDIT_WEBHOOK_URL, ZOSMF_PASSWORD, ZOSMF_REJECT_UNAUTHORIZED, ZOSMF_TOKEN, ZOSMF_TOKEN_FILE, ZOSMF_TOKEN_TYPE only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- <the server's command>

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

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-11 and scored it 80/100 (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.
