Inject live database context into Cursor

The `search` tool allows your agent to pull live vector similarity data during a coding session. Instead of relying on stale mock data, your agent reads actual records from your cluster. This allows the editor to generate code that matches your live database schema. You get accurate, context-aware suggestions every time you trigger a search.

Handle collection management inside Cursor

Use `list_collections` to verify your environment before writing your data access logic. It keeps you oriented within your database structure without breaking your workflow. When you need to clean up test records, just call the `delete` tool. It removes documents based on your filters, keeping your development environment predictable.

Execute index and document operations in Cursor

Define your indexing strategy using `create_index` directly in your project configuration. The agent manages the index build process so you can focus on the application logic. You can also use `insert` to populate your collections with valid data samples. It’s a fast way to test how your code interacts with real vector fields.

Setup guide

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

.cursor/mcp.json

{
  "mcpServers": {
    "mongodb-atlas-vector-search-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
