List LaunchDarkly Feature Flags
Retrieves existing feature flags from a LaunchDarkly project. Use this before calling create-flag to avoid creating duplicates.
Parameters
- project_key — LaunchDarkly project key (required)
- search — Optional text to filter flags by name or key
- tag — Optional tag filter (e.g.,
repo:my-org/my-repo)
- limit — Max number of flags to return (default: 20)
Steps
- Call the LaunchDarkly MCP
list_feature_flags tool with the project key and any filters.
- Return a summary list with each flag's key, name, and creation date.
- If a flag matching the intended key already exists, highlight it clearly.
Output format
Return a concise list:
Existing flags in project '{project_key}':
- `{flag_key}` — {flag_name} (created {date})
- ...
If no flags match, state "No existing flags found matching your criteria."
