What the honeypot saw
no credential files read · no network
What we could not test
what the tools do when called with real credentials

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names chatgpt.com, claude.ai, claude.com as well as its own vendor. The guard injects TRANSLOADIT_MCP_METRICS_PASSWORD, TRANSLOADIT_MCP_TOKEN, TRANSLOADIT_MCP_UPSTREAM_SECRET, TRANSLOADIT_SECRET only into requests to transloadit.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets TRANSLOADIT_MCP_METRICS_PASSWORD=transloadit.com,TRANSLOADIT_MCP_TOKEN=transloadit.com,TRANSLOADIT_MCP_UPSTREAM_SECRET=transloadit.com,TRANSLOADIT_SECRET=transloadit.com -- npx -y @transloadit/mcp-server

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 (2 scenarios) on 2026-11-12 and scored it 90/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: no network, touches nothing outside the project, writes no memory.
