Connect LaunchDarkly to Cursor

Expose selected local integrations to Cursor through KosmoKrator without configuring each service as its own MCP server.

Create or update .cursor/mcp.json with a KosmoKrator stdio server entry. The gateway is local, scoped to this integration, and starts with --write=deny so Cursor can inspect read-capable tools without receiving write access by default.

LaunchDarkly MCP Config for Cursor

Use the same KosmoKrator install and integration credentials that power terminal and headless runs.

Why Use KosmoKrator Here

Scoped tools

Expose only LaunchDarkly instead of a broad multi-service tool list.
