Build typed queries in Cursor with live schema data

The `execute_fql` tool gives your editor direct access to your database schema. Your agent runs queries to inspect collections, ensuring the TypeScript types it generates match your actual database documents. Instead of relying on outdated offline documentation, the editor checks the live database state. This prevents runtime type errors before you even commit your code.

Test FQL queries directly in the editor chat

Writing database queries becomes much faster when you run the `execute_fql` tool inside the Cursor composer. You ask the agent to test a query, and it executes the FQL against your dev database immediately. The response displays right in your sidebar. If the query runs slowly, the agent rewrites the FQL to use your defined indexes, optimizing performance on the fly.

Automate migrations using this MCP Server

Database migrations no longer require switching to a separate CLI tool when you run this MCP Server. Your agent reads your local migration files and runs the `execute_fql` tool to apply them. This keeps your database schema perfectly synced with your current git branch. You write the code, and the editor handles the database updates.

Setup guide

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

.cursor/mcp.json

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

Common questions about Fauna (Serverless DB) MCP in Cursor

Add the server to your Cursor MCP configuration file in your project root. Once configured, enable Agent mode in the chat panel to let the editor run database queries.

Yes, the Composer can run queries using the execution tool to build and verify database schemas. This allows the editor to modify your database structure while writing the corresponding application code.

Yes, the server reads your local environment variables to authenticate with the database. The editor passes these credentials securely to ensure you have the correct access levels.

Yes, the agent uses the execution tool to run index creation queries. It defines terms and values based on the query patterns you want to optimize.

Your database documents are retrieved locally by the editor process. Only the text results needed to answer your prompt are sent to the language model, and they are never stored on external MCP hosting servers.
