## Rules for an agent

- Get a free AppID in the developer portal (2,000 non-commercial calls/month); use the LLM API for compact text answers; commercial use needs a paid license; no caching of results; official MCP via WolframResearch/AgentTools or Wolfram Cloud MCP.
- Attribute Wolfram|Alpha and link to the corresponding results page wherever results are shown
- Do not cache results unless you have a written agreement
- Free AppID is for non-commercial use only (2,000 calls/month); commercial apps need a paid license

## Agent access

- MCP: https://github.com/WolframResearch/AgentTools (local MCP server, needs a Wolfram Engine or Docker image); also Wolfram Cloud MCP, free for limited personal use: https://www.wolfram.com/artificial-intelligence/mcp/cloud/
