+description: Routebase is an OpenAPI-native platform that keeps your API as a single source of truth. Teams design their OpenAPI description in a visual editor, then generate documentation portals, mock servers, contract tests, and drift monitoring from that one description. Change the description, publish, and Routebase flags whatever drifted. Every workspace also ships a built-in Model Context Protocol (MCP) server, so AI agents work from the same OpenAPI description.

+## Overview
+
+Routebase unifies the API lifecycle around one OpenAPI description. Documentation portals, mock servers, contract tests, and monitoring all derive from the same source, so they never drift apart. A built-in MCP server exposes the same workspace to AI agents under a team's permissions.
+
+## Features
+
+- Visual editor for OpenAPI descriptions — endpoints, schemas, and versions without hand-edited YAML
+- Documentation portals generated from the description, on your own custom domain
+- Mock servers generated straight from the description, with custom rules and proxy mode
+- Contract testing that validates live responses against the description and flags drift
+- Scheduled monitoring with field-level breaking-change detection
+- Spec branches with review and merge, plus breaking-change checks
+- Built-in Model Context Protocol (MCP) server for AI-agent access
