Connect LaunchDarkly to Claude Code

Connect local KosmoKrator integrations to Claude Code through one scoped MCP gateway entry.

Add KosmoKrator as a stdio MCP server in the Claude Code project config and select the integrations that should be visible. The gateway is local, scoped to this integration, and starts with --write=deny so Claude Code can inspect read-capable tools without receiving write access by default.

LaunchDarkly MCP Config for Claude Code

Claude Code can launch the local kosmo binary directly from the project MCP config.
