CellRune
Read, calculate, edit, and save XLSX workbooks headlessly over local stdio.
What it does
CellRune is an MCP server, a connector that lets an AI assistant use it as a tool. It is installed locally as a package and runs on your machine.
From the publisher's description, Electra Index matched it to one capability: spreadsheet automation. That makes it a candidate for tasks such as build financial models or clean and merge spreadsheets.
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.
