LaunchDarkly Automation

Automate your LaunchDarkly feature flag workflows -- enumerate projects and environments, create webhook-driven flag triggers, manage trigger lifecycle, and audit code references across repositories.

2. Connect your LaunchDarkly account when prompted (API key authentication)
3. Start using the workflows below

Core Workflows

1. List Projects

Use LAUNCH_DARKLY_LIST_PROJECTS to discover all projects and their keys for subsequent operations.

Tool: LAUNCH_DARKLY_LIST_PROJECTS
Inputs:
  - filter: string (e.g., "query:myproject" or "keys:proj1,proj2" or "tags:mytag")
  - expand: string (e.g., "environments" to include env list per project)
  - limit: integer (default 20)
  - offset: integer (pagination start index)
  - sort: string (e.g., "name" or "-name" for descending)

2. Get Environments for a Project

Use LAUNCH_DARKLY_GET_ENVIRONMENTS to list all environments within a project (production, staging, test, etc.).

Tool: LAUNCH_DARKLY_GET_ENVIRONMENTS
Inputs:
  - project_key: string (required) -- e.g., "my-project", "default"
  - filter: string (e.g., "query:production")
  - limit: integer (default 20)
  - offset: integer (pagination)
  - sort: string (e.g., "name" or "-name")

3. Create a Flag Trigger Workflow

Use LAUNCH_DARKLY_CREATE_TRIGGER_WORKFLOW to set up automated flag toggles triggered by external events (webhooks, Datadog alerts, etc.).

Tool: LAUNCH_DARKLY_CREATE_TRIGGER_WORKFLOW
Inputs:
  - project_key: string (required)
  - feature_flag_key: string (required) -- e.g., "new-feature", "enable-dark-mode"
  - environment_key: string (required) -- e.g., "production", "staging"
  - integration_key: string (default "generic-trigger") -- or "datadog", "honeycomb", "dynatrace"
  - instructions: array of objects (optional):
      - kind: "flag_action" (fixed)
      - action: "turnFlagOn" | "turnFlagOff"
  - comment: string (optional) -- description of the trigger purpose

The trigger generates a unique webhook URL that can be called to execute the configured flag action.

4. Delete a Flag Trigger Workflow

Use LAUNCH_DARKLY_DELETE_TRIGGER_WORKFLOW to permanently remove a trigger and its URL.

Tool: LAUNCH_DARKLY_DELETE_TRIGGER_WORKFLOW
Inputs:
  - project_key: string (required)
  - feature_flag_key: string (required)
  - environment_key: string (required)
  - id: string (required) -- the trigger ID returned during creation

Warning: Deletion is irreversible. The trigger and its URL cannot be recovered.

5. List Code Reference Repositories

Use LAUNCH_DARKLY_LIST_CODE_REFERENCE_REPOSITORIES to track where feature flags are used in your codebase.

Tool: LAUNCH_DARKLY_LIST_CODE_REFERENCE_REPOSITORIES
Inputs:
  - projKey: string (optional) -- filter by project key
  - flagKey: string (optional) -- filter by feature flag key
  - withBranches: string (any value to include branch data)
  - withReferencesForDefaultBranch: string (any value to include code refs for default branch)

Note: Code references is an Enterprise feature requiring code-reference-repository write permissions.

Known Pitfalls

Pitfall	Detail
Project key discovery	Always use LAUNCH_DARKLY_LIST_PROJECTS first to find valid project keys before calling other tools.
Environment key format	Environment keys are lowercase slugs (e.g., "production", "test"), not display names.
Trigger deletion is permanent	Once deleted via LAUNCH_DARKLY_DELETE_TRIGGER_WORKFLOW, the trigger URL is unrecoverable.
Enterprise-only code refs	LAUNCH_DARKLY_LIST_CODE_REFERENCE_REPOSITORIES requires Enterprise plan and write permissions.
Trigger instructions format	Each instruction object requires kind: "flag_action" (fixed constant) and action as either turnFlagOn or turnFlagOff.
