Frequently asked questions about the Flagsmith MCP Server
Can I retrieve flags for a specific user identity?
Yes. Use the get_identity_flags tool by providing the user's identifier. The agent will return all flags and traits associated with that specific identity in the environment.
How do I update multiple feature flags at once?
You can use the update_flag_v2 tool for batch changes. Provide the environment key and a JSON payload containing the updates you wish to apply simultaneously.
Is it possible to create a new environment via the agent?
Yes, using the create_environment tool. You will need to provide a name for the environment and the target Project ID. This requires a valid Flagsmith Admin API Key.
