Coverage

Server started and answered tools/list.

Tested: MCP initialize and tools/list · every tool description, for hidden instructions · every file read, file written and host contacted by what ran
Not tested: what the tools do when called with real credentials

Before you give it your token

It will ask for: SAPIENS_DESKTOP_SESSION_TOKENSAPIENS_SESSION_TOKENConfiguration, not credentials: CONVEX_URL, NEXT_PUBLIC_CONVEX_URL, SAPIENS_CONVEX_TIMEOUT_MS, SAPIENS_MCP_CANAL, SAPIENS_MCP_HOME, SAPIENS_MCP_NO_TELEMETRY, SAPIENS_TIER_OVERRIDE, SHARE_DROP_BASE_URL
Where it talks to: sapiensinteticos.com (its own)Also gstatic.com, fal.run, b-cdn.net, convex.cloud, linkedin.com, portfolio.com, site.com, company.com, google.com, medium.com, kie.ai, wavespeed.ai, replicate.com, openrouter.ai, x.com, aitag.app, sint.fyi — 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: 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 gstatic.com, fal.run, b-cdn.net, convex.cloud, linkedin.com, portfolio.com, site.com, company.com, google.com, medium.com, kie.ai, wavespeed.ai, replicate.com, openrouter.ai, x.com, aitag.app, sint.fyi as well as its own vendor. The guard injects SAPIENS_DESKTOP_SESSION_TOKEN, SAPIENS_SESSION_TOKEN only into requests to sapiensinteticos.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets SAPIENS_DESKTOP_SESSION_TOKEN=sapiensinteticos.com,SAPIENS_SESSION_TOKEN=sapiensinteticos.com -- npx -y sapiens-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) on 2026-11-11 and scored it 82/100 (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.
