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.

Toolkit docs: composio.dev/toolkits/launch_darkly

Setup

Add the Composio MCP server to your client: https://rube.app/mcp
Connect your LaunchDarkly account when prompted (API key authentication)
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. |
