Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 6 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Manually checking charity financials is a nightmare.

Right now, vetting a nonprofit means bouncing between the main site, the IRS database, state registries, and financial news sites. You're copying an EIN here, pasting it there, waiting for different pages to load, and trying to manually correlate which warning belongs to which rating year.

With this MCP, your agent handles the entire data crawl. Instead of juggling multiple tabs, you ask a single question—like 'Does this organization have any financial advisories?'—and get an instant, consolidated answer backed by structured data.

get_charity_ratings: Seeing how ratings actually change.

Before this MCP, you saw a static star rating on the homepage. If that score changed last year due to poor spending or governance issues, you had no easy way to verify that decline without digging through annual reports yourself.

Now, using `get_charity_ratings`, your agent plots the performance history over time. You see the full story: when they peaked, and more importantly, exactly when their financial health started slipping.

What your AI can actually do with this

Figuring out which non-profit gets your donation is complex work. You need more than just a pretty website; you need proof of financial health and accountability. This MCP lets your AI client talk directly to Charity Navigator, giving you deep access to nonprofit data without having to click through dozens of tabs or read dense tax forms.

You can search by location or cause area, pull up detailed records for any organization, and check its entire rating history instantly. It even alerts you if the charity has any active warnings about governance or finances. Vinkius hosts this MCP so your agent connects once, giving it access to this robust source of nonprofit information, making due diligence simple.

It cuts through the hype. You get reliable scores on financial stability and accountability, allowing you to research charities based on concrete data points rather than marketing materials.

Questions you might have

How do I get Charity Navigator API credentials? +

Visit charitynavigator.org, register for a free developer account, and you'll receive an App ID and App Key. Both are required for API access.

What does the rating scale mean? +

Charity Navigator rates nonprofits on a 0-4 star scale. 4 stars = exceptional performance, 3 stars = strong, 2 stars = adequate, 1 star = needs improvement, 0 = unrated or flagged. Ratings are based on financial health, accountability and transparency.

How do I search for charities by cause? +

Use get_categories to get all cause/category IDs, then use search_charities with the category_id parameter. Popular categories include education, health, environment, animal welfare, arts & culture, and human services.

What is an EIN? +

EIN stands for Employer Identification Number, a unique 9-digit identifier assigned by the IRS to US nonprofits. It's used as the primary key for looking up specific charities. You can find EINs in search results or on the charity's tax filings.

What should I do if I run get_charity_advisories and get zero results? +

No advisories means a clean record. This is a good sign, indicating the charity currently has no active warnings or flags from Charity Navigator regarding governance or finances.

What are the best filtering options when using search_charities? +

You can filter searches by many parameters including state, zip code, minimum expenses, and specific rating scores. This allows you to narrow results far beyond just name or cause.

If I want to find out what causes are available for filtering, should I use get_categories? +

Yes, run get_categories first. This tool returns the full list of all charity categories and their unique IDs, letting you filter your searches accurately.

When I use get_charity, what specific financial or legal documents appear? +

It provides a comprehensive view including mission statements, tax filings, detailed financial data, and official contact information. You get everything needed for due diligence in one call.
