# How to Compare Grant Programs with Claude

Search multiple grant programs and pull full details for a direct comparison. Use `search_opportunities` to find candidates and `opportunity_details` to get the specifics. Claude is particularly useful for interpreting nuanced eligibility criteria and explaining trade-offs between programs.

## Setup

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

## Steps

1. Connect ToolRouter in Claude: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Describe the type of funding you are looking for: sector, geography, applicant type, and approximate budget.
3. Use `grants-finder` with `search_opportunities` to find relevant programs across sources.
4. Run `opportunity_details` on the top candidates to pull full eligibility, funding, and deadline information.
5. Ask Claude to compare the programs side by side and recommend which ones deserve application effort.

## Example Prompt

```
Use grants-finder to search for climate adaptation funding for a US-based research institute. Pull the full details for the top 4 programs and compare them side by side. Tell me which ones have the best fit for a mid-size research team, which deadlines are realistic, and which I should skip.
```

## Tips

- Pull opportunity details for at least 3 programs so the comparison is meaningful.
- Ask Claude to flag eligibility blockers first before spending time on softer criteria like thematic fit.
- Include your preferred funding range so Claude can filter out programs that are too small or too large.
