SniffPup
Free passive outside security scan of a live web app: leaked keys, exposed files, open Supabase
What it does
SniffPup is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
From the publisher's description, Electra Index matched it to 2 capabilities: security scanning and sql querying. That makes it a candidate for tasks such as scan code for vulnerabilities or review pull requests.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.
