FAQ from Agent101 Mcp

What tools are available for free?

44 tools are free and require no API keys or setup. They cover data & reference (e.g., ipinfo, open-meteo, wikipedia), developer (e.g., github-search, pypi, hacker-news), finance (bitcoin-price), text & language (dictionary, duckduckgo), network & security (dns-lookup, ssl-check), space & science (iss-location, nasa-apod), media (open-library, lorem-picsum), and utilities (qrcode, catfact, bored).

How do I invoke a free tool?

Use the invoke_tool MCP tool with the invoker name and optional parameters. For example: invoke_tool("hacker-news") or invoke_tool("pypi", {"package": "requests"}).

What are the runtime dependencies?

Zero dependencies – the server runs on Python 3 with no additional packages required for the free tools. For the optional x402 payment gateway, install x402[all], fastapi, and uvicorn.

Can I add my own custom invokers?

Yes. You can add invokers by defining a function decorated with @invoker("tool-name") in the server script. The README provides a minimal example.

What authentication or payment systems are supported?

No authentication is required for free tools. The optional x402 payment gateway uses USDC on Base for premium API calls; free tools remain free even when the gateway is active.
