Setup

Two steps. One of them is a paste.

Works with any MCP client: Claude Code, Cursor, Windsurf, Cline, Zed, Claude Desktop. There’s nothing client-specific in the config.

Add one line to your MCP config

That’s the whole config. No key in it, so there’s nothing to rotate and nothing to leak if the file ends up somewhere it shouldn’t.

{
  "mcpServers": {
    "ocular": {
      "command": "npx",
      "args": ["-y", "useocular"]
    }
  }
}

Sign in once. $2.50 and you’re in.

The first time your agent asks to look at something, a browser tab opens: sign in, pick a plan, done. It closes itself. You won’t be asked again on this machine.

Then just ask.

Your agent decides when to look. You don’t call a tool, and you don’t paste a screenshot. You tell it what you’re building and it checks its own work.
