# How to Search Recipes by Dietary Restrictions with Claude

Claude helps you navigate dietary restrictions through iterative filtering. Start with one restriction, layer on additional constraints, and explore substitutions for recipes that almost qualify. The conversation builds a nuanced understanding of your dietary needs so each successive search gets more targeted.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Find gluten-free dinner recipes using recipe-finder"
3. Claude returns recipes that meet the dietary requirement
4. Ask: "Which of these are also dairy-free?"
5. Pick a recipe that fits all your dietary needs

## Example Prompt

```
Find vegan dinner recipes that are also gluten-free and nut-free. I need options for a dinner party with guests who have these restrictions.
```

## Tips

- Specify all dietary restrictions upfront for the most accurate filtering
- Ask Claude to suggest ingredient substitutions for recipes that almost meet your needs
- Request recipes sorted by simplicity for everyday cooking
