Full read-write Claude connector for LaunchDarkly
Let Claude toggle flags and update targeting in LaunchDarkly
Stop clicking through the LaunchDarkly dashboard to flip a flag or tweak a rollout. Claude reads flag state and makes the change in the environment you name, with production toggles and archiving gated behind your approval.
LaunchDarkly is a feature management and experimentation platform where teams control flags, rollouts, and targeting across environments. People want Claude to do more than report flag state: to flip flags, adjust targeting, and manage rollouts where the work already lives.
What is a LaunchDarkly MCP server?
A LaunchDarkly MCP server is a small hosted service that exposes LaunchDarkly's data and actions to Claude over the Model Context Protocol, so Claude can issues, code, and incidents inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can LaunchDarkly's current connector do today?
LaunchDarkly ships an official connector that exposes a standard tool set for flags and configs. A custom connector goes further: it shapes the toggles, targeting edits, rollouts, and segment changes your team actually runs, with scoped projects and environments and human-in-the-loop gating on production. Capabilities depend on the API token's permissions, so confirm scope before relying on it.
What does full read-write LaunchDarkly access unlock?
Full read-write LaunchDarkly access lets Claude toggle a flag in a specific environment, update targeting rules and percentage rollouts, add or remove flags from segments, and adjust a flag's default variation, once you approve. The flag changes that meant clicking through the dashboard happen where the request was made.
- Toggle a feature flag on or off in a specified environment
- Update targeting rules or percentage rollout for a flag
- Add or remove users and segments from a flag's targeting
- Change a flag's default variation or fallthrough behavior
- Create a new feature flag with variations from a description
- Archive or remove a stale flag after you confirm
Can Claude toggle a feature flag in LaunchDarkly?
Yes, Claude can toggle a feature flag on or off in a named environment when the connector has a write-scoped API token. It reads the flag's current state first, then flips it through a dedicated write tool. Production changes can be gated so Claude prepares the toggle and you confirm before it lands.
Can Claude update targeting rules in LaunchDarkly?
Claude can update targeting rules and percentage rollouts in LaunchDarkly, add or remove users and segments from a flag's targeting, and adjust the default variation or fallthrough. These run as write tools scoped to the projects and environments your token allows, so changes stay within the bounds you set.
Can Claude create or archive a flag in LaunchDarkly?
Claude can create a new feature flag with variations from a description, and archive a stale flag once you confirm. Creation flows from a write-scoped token, while archiving is a destructive action gated behind explicit approval. The connector never grants more access than the token you provide already has.
How a LaunchDarkly connector works
We build a small MCP server that authenticates to LaunchDarkly with a scoped API access token and the narrowest project and environment permissions the work needs. Read tools (list flags, read targeting) and write tools (toggle, edit targeting, archive) are separated, and destructive actions like archiving a flag require your confirmation. Claude only ever has the access your token already grants, and we can restrict the server to allowlisted IPs where your setup supports it.
