AI visibility: which buyer questions name your brand in ChatGPT, Perplexity, Claude, AI Overviews.
What it does
Proofsource 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: web research. That makes it a candidate for tasks such as fact-check a document or find influencers.
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.
