Perplexity

Instant flag toggling from Claude Desktop

Stop switching tabs to flip a feature flag when testing. Tell your Claude Desktop client to run `toggle_feature` to turn on a flag in staging, or run `list_features` to see what is currently active. Your agent handles the API calls in the background so you stay in your flow. If you need to make quick adjustments, the agent can use `update_feature` to modify targeting rules on the fly. You see the state changes instantly in your chat logs.

Fast environment setup via MCP Server

Spin up staging or testing environments without touching the GrowthBook UI. Your agent uses `create_environment` to set up new targets and `list_environments` to check what is already configured. This MCP Server lets you clean up old setups just as fast. Tell Claude Desktop to run `delete_environment` when a test cycle finishes to keep your workspace clean.

Multi-project coordination via MCP Server

Organize your workspaces using the GrowthBook MCP Server. Your agent uses `list_projects` to find the right scope, then calls `create_project` or `update_project` to structure your workspaces. When debugging, ask Claude Desktop to run `get_project` to inspect project-level configurations. It pulls the exact metadata you need to troubleshoot scoping issues.

Yes. You can tell Claude Desktop to run `create_project` with your specified parameters. It will register the new project and return the ID.

The client uses `list_environments` to see all configured targets. From there, you can ask it to run `update_environment` or target specific flags to those environments.
