Every Squirrels project has an MCP server running at /mcp automatically. Thus, AI tools that support the Model Context Protocol can be used to ask questions about the datasets configured in a Squirrels project. To make it easy for anyone to follow along, we will use the following MCP server URL for a mortgage analytics Squirrels project that is publicly accessible. 
https://mortgage-squirrels-example.duckdns.org/mcp
You can replace this URL with the MCP server URL for your own Squirrels project when working with this guide (such as http://localhost:4465/mcp).

Example prompts

The following are sample prompts that can be used for any Squirrels project when interacting with an AI chat agent: 
What datasets do you have access to?

What tools do you have access to?
The following are sample prompts specific to the mortgage analytics Squirrels project: 
Suppose I have a 500K loan amount at 5% mortgage rate for 20 years remaining. What would be the monthly mortgage payment?

Suppose I have a 500K loan amount at 5% mortgage rate for 20 years remaining. Should I pay off the full 500K now, or keep the mortgage and invest it in the stock market instead? Run 1000 simulation trials to answer.
