- Describe the type of funding you are looking for: sector, geography, applicant type, and approximate budget.
- Use `grants-finder` with `search_opportunities` to find relevant programs across sources.

- Ask Claude to compare the programs side by side and recommend which ones deserve application effort.
Example Prompt
Try this with Claude using the Grants Finder tool
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.
