Perplexity

Build with real nonprofit data

Stop using mock data for your charity-focused app. Tell the agent to hit the `search_charities` tool and write the code that handles the live API response. You get working code that uses real nonprofit information from day one. This is perfect for building donation features or internal dashboards. You can test your logic against actual data structures for charity names, EINs, ratings, and financial summaries.

Automate data gathering scripts

Need to pull data for a specific list of nonprofits? Give the agent the EINs and have it call `get_charity` for each one. It can generate a script to pull mission statements, websites, and financial data into a CSV or JSON file. You can also use `get_charity_ratings` and `get_charity_advisories` to automatically flag any organizations with poor ratings or active warnings. This MCP Server makes quick work of data-heavy research tasks.

Explore the API without leaving your editor

Instead of reading API docs, just ask the agent what's possible. Use `get_categories` to see all the available cause areas you can filter by. The agent can show you the exact structure of the data you'll get back. This makes discovery fast. You can figure out exactly what data you need from Charity Navigator and have Cursor's agent write the code to fetch it, all in one place.

Setup guide

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Charity Navigator MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Charity Navigator transactions." If the MCP tools are loaded correctly, Cursor will call the Charity Navigator tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about Charity Navigator MCP in Cursor

Yes. For example, you can ask the agent to find charities with `search_charities`, then write a Python script to loop through the results and call `get_charity_ratings` for each one. The agent will generate the code for you.

Just tell the agent to search for the charity by name. It will use the `search_charities` tool, which returns the EIN along with other basic info. You can then use that EIN in other tool calls.

Definitely. The `search_charities` tool has parameters for `rating` (a 0-4 scale) and `sizeRange` (based on total expenses). Just tell the agent your criteria, like "find 4-star charities with over $1M in expenses".

It returns warnings that Charity Navigator has issued for a nonprofit. These can be about issues with financial management, questionable fundraising practices, or problems with governance. It's a key tool for vetting an organization.

Absolutely not. Your agent only sends the specific tool calls, like a `search_charities` query, to the Vinkius-managed server. Your codebase and other project files are never transmitted or accessed. The connection is ephemeral and sandboxed.
