proofite-mcp@1.2.0
VERIFIEDPublisher claims: "Read your AI-written daily briefing and retune the filter behind it: feeds, newsletters, topics." Observed in sandbox: calls proofite.com only, touches nothing outside the project, writes no memory.
Coverage
Started with a decoy PROOFITE_API_KEY; tool list observed. Tool calls with a real credential not tested.- Tested
- server startup with a tagged decoy in PROOFITE_API_KEY · MCP initialize and tools/list · every tool description, for hidden instructions · where the decoy credential went · every file read, file written and host contacted by what ran
- Not tested
- what the tools do when called with a real credential
- Needs
- PROOFITE_API_KEY — give it to the server where it runs, through vet-skills run --secrets, so the value never enters the server's environment. Never paste a credential into a chat, a ticket or a report.
Before you give it your token
- It will ask for
PROOFITE_API_KEYConfiguration, not credentials: PROOFITE_KEY, PROOFITE_MCP_URL- Where it talks to
- proofite.com (its own)
- What the honeypot saw
- no credential files read · reached only proofite.com (its own)
- What we could not test
- what the tools do when called with a real credential
Connect it with a scoped credential, under the guard. It asks for PROOFITE_API_KEY and talks to proofite.com. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind.
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 2026-11-13 and scored it 92/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: calls proofite.com only, touches nothing outside the project, writes no memory.
