LaunchDarkly's hosted MCP server lets AI assistants create, update and inspect feature flags, work with AI configs and query observability data. It is remote and authenticates with OAuth, replacing the older access-token setup. EU and Federal instances are not supported by the hosted server and use LaunchDarkly's self-managed local server instead.
