What is the LaunchDarkly Local MCP Server?

LaunchDarkly’s local MCP server is the self-managed option documented for its EU and federal environments. It exposes supported feature-management operations, including flags and environment-related configuration. The maintainer recommends the separately hosted service where that service is available.

Inspect a flag in its target environment

Specify the project, flag and environment before asking about targeting or variations. Read the existing configuration before proposing a rollout change. Keep the environment visible in the result, because changing a development flag and changing a production flag are different operations.

Use the real package and regional configuration

The npm package is @launchdarkly/mcp-server; --package in the launch example is an npx option, not a package identifier. Follow the README’s full launch arguments and API-key instructions. The --server-url option selects the documented LaunchDarkly environment. Choose this local profile when its regional deployment model matches the account.
