What you can do with this MCP connector
You're talking to your AI client about charity vetting, right? This server hooks up your agent to Charity Navigator, letting you dig into the financial health and governance of over 175,000 US nonprofits. You can search for charities by name, zip code, cause area, or minimum star rating using search_charities.
You can also filter searches by specific cause categories—like education or health—by calling get_categories. To see a full picture of a charity, use its EIN to pull its entire profile, including its mission, address, financials, and tax filings, with get_charity. You'll get a history of a charity's scores—financial health, accountability, and transparency—over time by running get_charity_ratings.
Need to know if a charity has any current red flags? Check for specific warnings or alerts using get_charity_advisories, or pull a list of every charity with an active governance or financial warning across the board with get_all_advisories. You can assess an organization's financial risk by using get_charity_advisories to check for warnings, and then use get_charity to pull its detailed financial records and tax filings automatically.
How Charity Navigator MCP Works
- 1 Subscribe to the server and provide your free Charity Navigator App ID and App Key.
- 2 Your AI client executes a query (e.g., 'Find top-rated animal welfare charities in Texas').
- 3 The server processes the request, runs the necessary tools (like
search_charities), and returns a structured report with all the requested data points.
The bottom line is, you don't need to jump between multiple websites or databases; you ask your agent one question, and it pulls the structured data for you.
Who Is Charity Navigator MCP For?
Anyone who has to vet an organization before committing time or money. This is for donors, grant managers, investigative journalists, and philanthropic researchers. If your job involves checking credentials, this saves hours of manual cross-referencing.
Needs to quickly check the financial stability and advisory history of multiple potential grant recipients.
Uses the server to pull tax filings, check for governance warnings, and verify mission statements for articles.
Researches charities by cause area and rating before advising clients on where to donate.
What Changes When You Connect
- See a charity's true financial stability. Don't just look at the current star rating; use
get_charity_ratingsto track historical performance and see if the score has dipped over time. - Cut through the hype. Instead of trusting a single rating, run
get_charity_advisoriesto immediately check for specific governance or financial warnings. - Scope out entire fields. Use
get_categoriesto browse every possible cause area (health, education, etc.) and find top-rated groups in that niche. - Build a full profile instantly. Instead of opening multiple tabs,
get_charitypulls the EIN, mission statement, financials, and contact info all in one call. - Focus your search. Use
search_charitieswith filters for location, size, or minimum rating to narrow down the 175,000+ options fast. - Track risk across the board. Use
get_all_advisoriesto get a comprehensive, system-wide list of all organizations flagged for review.
Real-World Use Cases
Due Diligence on a Potential Grantee
A grant manager needs to verify a startup nonprofit. They ask their agent to run search_charities filtered by 'education' and 'California'. The agent finds three candidates, then runs get_charity_ratings and get_charity_advisories on the top result to confirm its financial health and check for any recent warnings. They get a full risk report in minutes.
Researching a Donation Target
A donor wants to give money to a specific cause, like environmental cleanup. They ask the agent to find top-rated groups using search_charities and get_categories (for environment). The agent returns a list of top options, including their star ratings and financial size, so the donor can pick the best fit.
Investigating a Company's Claim
A journalist writes about a 'Red Cross' type organization. They ask the agent to run get_all_advisories to see if any organization with 'Red Cross' in its name is flagged. If nothing comes back, they have instant proof of a clean record.
Comparing Multiple Nonprofits
A philanthropist needs to compare three charities in the same city. They ask the agent to use search_charities for the city, then loop through the results, calling get_charity_ratings and get_charity for each one to create a side-by-side comparison of financials and historical scores.
The Tradeoffs
Manual Cross-Referencing
Opening the charity website, finding the EIN, then navigating to a separate rating site, and finally searching a third database for tax filings. This takes hours and relies on copy-pasting.
→
Instead, ask your agent to run search_charities first, then pass the EIN to get_charity and get_charity_advisories. This gets the entire data set in one flow.
Ignoring Rating History
Assuming a charity is safe because its current star rating is 4/4 stars. This ignores potential dips in financial health or governance issues that happened last year.
→
Always check the trend using get_charity_ratings. This tool shows the full timeline of scores, letting you see if the current rating is stable or if it's a sudden recovery.
Missing Contextual Warnings
Only running a simple search on name and location, which misses crucial alerts about financial mismanagement or governance problems.
→
Always follow up the search with get_charity_advisories and get_all_advisories. This ensures you catch systemic warnings that aren't tied to a single name or location.
When It Fits, When It Doesn't
Use this server if your goal is comprehensive due diligence on a nonprofit. Specifically, you need to correlate a charity's mission (via get_charity) with its financial risk (via get_charity_advisories and get_charity_ratings). Don't use this if you just need general company data; use a simple business directory tool instead. If you only care about ratings and not the underlying financials, you're missing half the picture. Always run search_charities first, then pass the results to get_charity_ratings to get the full picture.

Available Capabilities
Vetting a Nonprofit Shouldn't Require 10 Tabs and 3 Hours.
Today, vetting a charity is a mess. You start on one site, find the EIN. Then you copy that EIN to a second site to check the rating, and finally, you open a third tab to search for tax filings. You spend the day copy-pasting IDs and jumping between disparate websites just to build a basic risk profile.
With Charity Navigator, you just tell your agent what you need. It handles the entire sequence: it finds the nonprofit via `search_charities`, pulls the financial data with `get_charity`, and gives you the advisory status. You get a single, structured report that tells you everything you need to know.
Charity Navigator MCP Server: Check Advisory Status with `get_charity_advisories`
Manual checks for warnings are slow. You have to find the organization, then manually look for a 'warning' section, hoping the information hasn't been moved or deleted. It's a guessing game.
Now, you ask your agent to run `get_charity_advisories`. It checks the system, finds any issues—whether with governance or finances—and delivers a clean report. You know immediately if the charity is flagged, period.
