Inject flag state into Cursor

Stop guessing if a flag is active. Use `get_feature_flag` to pull the current configuration into your context window while you write code. The AI sees the actual rule set and applies it to the code it generates. This prevents the common problem of writing logic for a flag that is currently disabled.

Audit flag history in Cursor

Check the modification timeline without switching windows. Invoke `list_audit_logs` to see the recent changes for any flag directly in your editor. This gives you instant context on why a flag might be behaving differently than expected. You can see the change history as you review your implementation.

Manage project metrics via Cursor

Validate your experiments by checking metric data. Use `list_metrics` and `get_metric` to see how your features perform based on live traffic. Cursor uses this data to help you understand if a feature is ready for full rollout. You get the actual numbers rather than relying on stale documentation.

Setup guide

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

.cursor/mcp.json

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