Code with Live Federal Data

The Data.gov MCP server connects Cursor's Agent mode directly to the federal open data catalog. You are building a climate dashboard, and your AI writes the fetch calls using actual government endpoints instead of mock data. This completely eliminates the phase where you hardcode fake JSON just to test your UI. Cursor triggers `search_datasets` while you write your frontend components. The agent reads the exact schema returned by `get_dataset` and types your TypeScript interfaces automatically. You get working code that consumes real agency data on the first try.

Discover Agency Endpoints via Cursor

Finding the right federal API endpoint via the Data.gov MCP server usually replaces digging through terrible government documentation. Cursor handles that discovery phase right in your editor. Your AI client maps out the exact agency structure before writing a single line of code. The agent uses `list_organizations` to grab the correct department identifiers. It then runs `get_organization` to pull the contact info and `get_organization_datasets` to find the specific API endpoints that agency maintains. Your code gets wired up to the right source immediately.

Automate Format Validation

Government data inside the Data.gov MCP server comes in wildly inconsistent formats across different departments. Cursor needs to know if a resource is a clean API or a messy Excel file before attempting to write a parser for it. Checking the file type early prevents your agent from writing useless integration code. By checking `list_resource_formats`, Cursor understands what kind of parsing logic to write. The agent then uses `get_group` and `get_group_datasets` to find finance or agriculture records that specifically match the formats your application actually supports.

Setup guide

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

.cursor/mcp.json

{
  "mcpServers": {
    "datagov-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}

Common questions about Data.gov MCP in Cursor

Create a configuration file in your project root directory. Paste the server settings into the file and turn on Agent mode in your chat panel. The AI immediately recognizes the federal catalog tools.

Yes, the AI uses the catalog metadata to understand the exact structure of the federal resource. It generates the fetch requests and the corresponding TypeScript types based on the real data dictionary. You skip the manual typing phase entirely.

Your editor filters the 300,000+ records down to a single department. Tell the agent to target the EPA or NASA, and it restricts its queries to those organizations. This keeps your project focused on the exact domain you are building for.

The base catalog search functions without authentication. Vinkius manages the endpoint connection so you only need your standard workspace token. Your agent starts querying public records the second the configuration saves.

The integration only transmits the specific search strings and format tags your agent requests. Your proprietary source code and local environment variables never touch the government API. Every request routes through an ephemeral Vinkius sandbox that drops the connection immediately after fetching the metadata.
