What is a Claude plugin for AI visibility?
Claude plugins bundle connectors and skills into one install. A connector gives Claude access to a service's tools; a skill is a written procedure Claude follows when a task matches it, such as "audit my AI visibility". Together they turn a general assistant into one that knows how to do a specific job well and repeatably.
A Claude plugin for AI visibility teaches Claude how to read and act on data about how AI answer engines describe a brand. With it, Claude adds fresh measured numbers about what ChatGPT or Perplexity tell your buyers today to everything it already knows, and follows a set method, so two audits a week apart are comparable.
The Proofsource plugin connects Claude to the Proofsource MCP server with your sign-in and adds two skills. Each claim in the audit points back to the data it came from, and the fix plan never logs a question or a fix without asking you first.
How it works
A Claude plugin with two skills: a sourced AI visibility audit and a ranked fix plan, both reading your Proofsource data.
Install the plugin
In Claude Code, add the Proofsource plugin marketplace and run /plugin install proofsource.
Sign in once
Run /mcp, pick proofsource and sign in with your Proofsource account in the browser window.
Run the audit
Ask "Audit my AI visibility" and Claude follows the audit skill: visibility by engine, competitors, cited sources and recent changes, each sourced.
Get a fix plan
Ask for a plan and the fix plan skill ranks open gaps. Say yes and it tracks new questions or logs shipped fixes.
