## APIs (3)

- **Management API** — Programmatic access to Featureflip — projects, environments, feature flags, variations, targeting, segments, and SDK keys. Bearer-token auth (ffp_ personal / ffs_ service tokens).
- **Evaluation API** — High-performance feature flag evaluation service for SDKs, with client and SDK endpoints for evaluation, identify, streaming, flags, and events.
- **MCP Server (local)** — Documentation for the @featureflip/mcp server, a local stdio process run via npx that calls the Management API on your behalf using a bearer token.
