What it does

DataClean is an MCP server, a connector that lets an AI assistant use it as a tool. It can be used hosted (nothing to install) or installed locally.

From the publisher's description, Electra Index matched it to one capability: spreadsheet automation. That makes it a candidate for tasks such as clean and merge spreadsheets or build financial models.

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.

Live check

Electra Index connected to the hosted endpoint 6h ago

REACHABLE The endpoint answered but asks for an API key or a sign-in before connecting. Electra Index never sends credentials, so the tool list is not visible here.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
