The charity MCP server for AI agents
Give your AI assistant verified data on 7M+ nonprofits across 65+ countries, sourced from official government registries. Search, verify registry numbers, and compare integrity scores - structured, current, and free to start. No scraping, no hallucinated charity facts.
Listed in the official MCP registry as com.giveradar/charity-registry
Why an MCP server instead of scraping?
No hallucinated charities
When users ask an assistant "is this charity legit?", models guess. With MCP, your agent answers from 50+ official registries - every result carries its government registration identifier.
Structured, not scraped
Full schema.org JSON-LD per charity: registration, location, category, integrity score, FAQs. One tool call replaces parsing HTML, and it is always the current record.
Verification built in
Look up any EIN, UK Charity Number, RSIN, or local registry ID and get the registered organisation back - the core due-diligence step donors ask agents to do.
Four tools your agent can call
search_charities
Free-text name search across 7M+ organisations, optionally filtered by country. Returns slug, location, category, and integrity score.
verify_charity
Look up by official registry identifier - EIN (US), Charity Number (UK), RSIN (NL), and equivalents. Handles formatting variants like "13-1760110".
compare_charities
Side-by-side integrity scores, founding years, and (on Pro) program, admin, and fundraising ratios for 2-5 charities, with a deterministic verdict.
find_similar
"More like this" - charities in the same country and cause category, ranked by integrity score.
