How to Use the NationBuilder MCP in Cursor

Q: Will Cursor automatically test my NationBuilder API calls?

The agent can execute endpoints like getapistatus to verify connectivity. It runs the actual request and uses the response to write your error handling logic.

Build campaign apps faster by letting Cursor pull live NationBuilder data via this MCP Server directly into your code.

Perplexity

Code with Live Supporter Data

Writing integration code usually means mocking up fake user profiles. With this MCP integration, Cursor's agent uses `list_nation_signups` to fetch actual supporter records while you type. You see the real JSON structure immediately. If you need to test an edge case, have the agent run `find_signup_by_email` or `get_signup_details`. It pulls the exact API response into your editor context. Your data models match reality on the first try.

Automate Donation Logic in Cursor

Building finance dashboards requires accurate transaction data. Instead of guessing the payload structure, ask Cursor to execute `list_recent_donations`. The AI reads the live data and writes the parsing logic for you. Testing write operations is just as fast. When you build a payment webhook, the agent can trigger `record_donation` to verify your code works against the real API using this MCP connection. You stop wasting time reading documentation and start shipping features.

Build Better CMS Integrations with this MCP Server

NationBuilder powers complex websites. When you write custom templates, Cursor can call `list_nation_sites` to grab your active site IDs. It feeds that context straight into the script you are working on. You can also pull event data using `list_upcoming_events` or check available categories with `list_signup_tags`. The agent maps the API relationships in the background. You just focus on the frontend code.

Setup guide

Set up NationBuilder MCP in Cursor

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 NationBuilder 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 NationBuilder transactions." If the MCP tools are loaded correctly, Cursor will call the NationBuilder tools automatically. You can also check Settings → MCP for a green status indicator.
