Tools (4)
🟢search_charities(query, country, limit)
Search the charity registry by free-text name. Returns up to `limit` matches, each with slug, name, country, city/state, foundation_type, integrity_score, and the canonical page URL. Use this BEFORE resources/read when the user names a charity but you don't know its slug. The match is case-insensitive substring on the charity's name.
Input Schema

"type": "object",
"properties": {
"query": {
"type": "string",
"description": "Name search query, 2+ chars."

"description": "Optional ISO 3166-1 alpha-2 country filter (e.g. 'ID', 'NL')."
},
"limit": {
"type": "integer",
"minimum": 1,
"maximum": 25,
"default": 10
}
},
"required": [
"query"
]
}🟢compare_charities(slugs)
Side-by-side comparison of 2-5 charities by slug. Returns their integrity scores, program/admin/fundraising ratios, annual revenue, founding year, foundation type, and a deterministic verdict on which has the strongest transparency signal. Use this when the user wants to choose between named charities.

}

}🟢find_similar(slug, limit)
Given one charity's slug, return up to `limit` other charities in the same country + category. Useful for 'find more like this' recommendations. Excludes the input charity from the result.

Look up a charity by its official registry identifier - EIN (US), Charity Commission number (GB), RSIN (NL), AHU/Kemenkumham reg number (ID), or a generic registration_number for other countries. Returns the matched charity or null. Use this when the user provides a registry number and wants to confirm what's registered under it.
