Perplexity

Terminal-first access to trivia

Claude Code executes `get_trivia_fact` directly from your command line. It pipes the result into your logs or scripts without any GUI overhead. This is perfect for automation. You define the target number, and the agent returns the fact as a clean string in your shell.

Math facts in your pipeline

Your CI/CD jobs can now pull mathematical properties using `get_math_fact`. Claude Code fetches the data, verifies the result, and continues the build process. It is built for speed. The tool output is ready for any downstream script you have configured in your environment.

Historical facts for backend dev

Use `get_year_fact` to inject historical context into your backend logs or documentation. Claude Code pulls the data and formats it for your terminal output. This MCP Server behaves like a standard utility. You call it, you get the fact, and you move to the next command.
