LaunchDarkly Copilot Agent

A GitHub Agent HQ & Copilot CLI plugin that creates and manages LaunchDarkly feature flags and AI Configs directly from pull requests, issues, and discussions.

Install the GitHub app, then @-mention or assign the agent on a PR/issue and it will analyze the diff, detect rollout candidates or LLM calls, and create the right flag or AgentControl Config in LaunchDarkly.

What it does

• Feature flag automation — Detects new behavior, conditional logic, or rollout language in PRs/issues and creates a flag with derived key, tags, and description. Avoids duplicates by checking LaunchDarkly first.
• AI Config automation — Spots direct LLM provider calls (OpenAI, Anthropic, Bedrock, Gemini, Strands) and hardcoded prompts/models, then creates or migrates them to a managed AI Config.
• Targeting & guarded rollouts — Configures percentage rollouts, attribute rules, segments, and health-monitored ramps.
• Cleanup — Removes stale flag evaluations and archives flags after a rollout completes.

The main agent uses the LaunchDarkly MCP server (https://mcp.launchdarkly.com/mcp/fm) via a bearer token supplied as COPILOT_MCP_LD_API_KEY.

Install

Install the LaunchDarkly Agent GitHub app in your repository or organization in order to manage LaunchDarkly feature flags and AgentControl configs

Required secret

Set COPILOT_MCP_LD_API_KEY as an Agent secret in the repository (or org) where the plugin runs. The COPILOT_MCP_ prefix is required for the value to be routed to the MCP server.

Conventions

• Flag and AI Config keys are lowercase, hyphen-separated (e.g., new-checkout-flow, support-ticket-summarizer).
• Flags are tagged with repo:<owner>/<repo> and pr:<n> / issue:<n> for traceability.
• AI Configs use agent mode when they need tools or hand-offs; completion mode for one-shot prompts.
• When no LaunchDarkly project is wired up, the agent runs aiconfig-projects first rather than guessing structure.
