Claude Connectors does not publish install or usage counts, so PluginStats tracks Daffy MCP's listing placement instead, currently position #828 in the marketplace's popularity-sorted listing.
About Daffy MCP
Daffy is a donor-advised fund: one account for all your giving. Add cash, stock, or crypto, get your tax deduction when you contribute, invest it to grow tax-free, and give to any of 1.5 million+ US charities whenever you're ready.
With Daffy in Claude, your giving is one question away:
• Know where you stand. Ask for your balance, how much you can give right now, how your fund is invested, and how it has performed. • See your giving history. Pull up donations by year or charity, review your contributions, and export a fund statement as CSV for tax time. • Find the right charity. Search 1.5M+ US nonprofits by name or cause, or look one up by EIN, and get its mission, location, website, and Daffy profile.
Everything runs through your existing Daffy account with your normal login. Read-only questions never change anything.
You'll need a Daffy account (daffy.org). Available to Daffy members in the US.
