Flagsmith is a feature flag and remote configuration platform for managing releases, experiments, and user targeting across applications. It is available as a hosted service, private cloud, or self-hosted open source deployment.
Flagsmith exposes two HTTP APIs (Admin API and Flags API), a remote MCP server, and an npm CLI; the APIs and CLI use either an organisation API key or environment key depending on surface, and the MCP server supports either interactive OAuth or an organisation API key.

In the Flagsmith dashboard, open your organisation, go to the API Keys tab in Organisation Settings, and click Create API Key. The auth docs are at Admin API Authentication.
In the Flagsmith dashboard, open your project, go to the Environments tab, and copy the client-side Environment Key for the environment you want to use. See Flags API Authentication.
Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
