Use with Claude Code

Setup

Get your personal MCP URL

Add UniversalBench

From any directory:

claude mcp add universalbench https://universalbench-mcp.penantiaglobal.workers.dev/u/ubk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

No --header flag needed. The URL carries your auth.Or edit ~/.claude/mcp_config.json directly:

{
  "mcpServers": {
    "universalbench": {
      "url": "https://universalbench-mcp.penantiaglobal.workers.dev/u/ubk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
    }
  }
}

Verify it connected

claude mcp list

UniversalBench should appear with status “connected”.

What you can do now

Ask Claude Code things that need real execution:

Find every TODO in the codebase, group by file, and write a summary to TODO_OWNERSHIP.md.

Claude Code uses UniversalBench to grep across your repo at remote speed, then use Python to group and format the results into Markdown.

Or for pipelines:

Search the web for the latest CVE alerts in the libraries my project uses. List anything critical from the last 7 days.

Claude Code chains web_search for the CVE data, code for parsing and filtering, and returns the result.

Problem	Fix
`claude mcp list` shows “disconnected”	Run `claude mcp logs universalbench` to see the underlying error
401 or 403 errors	URL token has a typo. Paste it again from the dashboard
Tool calls timeout	Use `session_id` to keep state warm between calls and avoid repeating expensive setup
