How to Use the KnowFirst MCP in Cursor

Q: Why does Cursor need the KnowFirst custom query tool?

The querycustomintelligence tool allows Cursor to fetch precise, filtered JSON payloads. This lets the editor generate accurate TypeScript interfaces based on the actual structure of the intelligence database.

Q: How do I debug KnowFirst MCP connection issues inside Cursor?

Run checkknowfirstapistatus through the Cursor terminal or chat. If the status check fails, verify your Vinkius token inside your .cursor/mcp.json file.

Generate production-ready code using real-time market data injected directly into Cursor using KnowFirst.

Query custom intelligence directly inside Cursor

`query_custom_intelligence` executes raw JSON query parameters to fetch structured market data directly into your Cursor editor. The Cursor agent uses this tool to pull live API responses, letting you write code against actual payloads instead of guessed schemas. This workflow eliminates the need for mock data files in your test suites. You get real, structured outputs that your editor uses to auto-complete typed interfaces.

Inspect data sources using this Cursor MCP Server

`list_intelligence_sources` returns the complete catalog of public records, social signals, and news feeds used by the database. Having this list exposed to Cursor allows your editor to validate where your application's intelligence data originates. The Cursor agent reads these source listings to help you build filtering logic in your code. You can programmatically exclude specific feeds based on the source metadata returned.

Retrieve raw entity data points for code generation

`list_entity_data_points` extracts unformatted data records for any specified entity ID inside Cursor. Your agent reads these raw points to generate precise database schemas and migration scripts that match the incoming intelligence feed. Instead of switching back and forth between API documentation and your editor, the raw data points land right in your active file. This keeps your focus on writing the parser logic.

Setup guide

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

.cursor/mcp.json

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

Common questions about KnowFirst MCP in Cursor

Add the KnowFirst configuration to your global or project-level `mcp.json` file. Once saved, Cursor detects the MCP tools automatically, allowing the Cursor agent to call them during chat or inline edits.

No, Cursor requires you to run in Agent mode, and you can monitor every tool call. You will see exactly when the editor executes a tool like `search_intelligence_entities` and what data it receives.

The `query_custom_intelligence` tool allows Cursor to fetch precise, filtered JSON payloads. This lets the editor generate accurate TypeScript interfaces based on the actual structure of the intelligence database.

Run `check_knowfirst_api_status` through the Cursor terminal or chat. If the status check fails, verify your Vinkius token inside your `.cursor/mcp.json` file.

Your audited entity changes and query parameters are processed through Vinkius's zero-trust sandbox. The MCP protocol ensures Cursor only receives the data requested by your active agent, keeping your API keys and local codebase completely isolated.
