# Beavy

> Beavy gives every API a single contract — instantly mocked for whoever's waiting, and continuously checked against what's actually shipped.

Beavy is built for frontend/backend split teams whose API drifts out of sync as they build in parallel (it also works well for a solo builder, even when it's just you). Define a contract with any MCP-compatible AI assistant, get an instant mock so the other side isn't blocked, then point Beavy at the real endpoint once it ships to catch drift automatically — no OpenAPI spec required.

## Core concepts

- Contract: the single source of truth for an API endpoint's shape, defined through natural conversation with an MCP-compatible AI assistant (e.g. Claude Code, Cursor) — no manual spec-writing.
- Mock: Beavy serves a working mock of a contract instantly, so whoever's waiting on the API (a frontend teammate, another service) isn't blocked.
- Validation: Beavy calls your live endpoint directly and checks the real response — status code, schema, field types — against the saved contract, flagging drift immediately.
