Statsig is a feature flagging, experimentation, and product analytics platform. It provides tools for managing gates, configs, experiments, metrics, and related project settings.
Statsig exposes two authenticated HTTP APIs (a Console CRUD API and an evaluation/events HTTP API), an OAuth-protected MCP server at https://api.statsig.com/v1/mcp, and the npm-distributed `siggy` CLI.

In the Statsig Console API overview, Statsig says Console API requests use a STATSIG-API-KEY header whose value is a Console API Key. Create one in Project Settings → API Keys. For CLI setup, the docs also point to Statsig Console settings → Keys & Environments to copy the Console API Key.
For the HTTP API, Statsig documents that you can use a Client-SDK Key in the statsig-api-key header. In Statsig Console settings, open Project Settings → Keys & Environments and copy the Client API Key as described in the HTTP API overview and CLI introduction.
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.
