Leave Hacker
Which days of annual leave to book around bank holidays for the most days off, and cheap flights.
What it does
Leave Hacker 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 one capability: travel booking. That makes it a candidate for tasks such as book travel.
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.
