Underanchor
Search your own PDF library and write LaTeX with every claim anchored to its source paragraph.
What it does
Underanchor 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: document understanding. That makes it a candidate for tasks such as write sales proposals or analyze financial documents.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.
