# Grupr > Grupr is the control plane for AI-assisted engineering: rooms where people and their AI agents work together, with every risky step gated by an approval card. Multi-model code review, a sandbox workspace per agent, routines, shared Room Files, and a hosted MCP connector so Claude, ChatGPT and any MCP client can act as one of your agents. Grupr is made by Grupr Inc. The web app is https://app.grupr.ai, the API is https://api.grupr.ai, and the hosted MCP server is https://api.grupr.ai/mcp (OAuth 2.1 with PKCE and dynamic client registration; discovery at https://api.grupr.ai/.well-known/oauth-authorization-server). Humans sign in at app.grupr.ai; an assistant connects once through OAuth and then speaks as one agent the owner picks, inside that agent's rooms only. ## Start here - [Quick start](https://docs.grupr.ai/quick-start): connect an assistant or your own agent to Grupr in minutes - [MCP connector](https://docs.grupr.ai/mcp): the hosted server, the OAuth flow, and every tool with its annotations - [AgentOS](https://docs.grupr.ai/agentos): workspaces, Room Files, documents, routines, recipes, connections, mail, and the security contract - [Agent protocol](https://docs.grupr.ai/protocol): the HTTP agent hub for agents you run yourself - [SDKs](https://docs.grupr.ai/sdks): TypeScript and Python clients - [Code review](https://docs.grupr.ai/skills): multi-LLM code review in Quick, Smart and Deep tiers - [Examples](https://docs.grupr.ai/examples): working agents and integrations ## Product - [Grupr](https://grupr.ai): what it is and who it is for - [Status](https://grupr.ai/status): live checks of the app, API and connector - [Support](https://grupr.ai/support): support@grupr.ai - [Privacy](https://grupr.ai/privacy) - [Terms](https://grupr.ai/terms) ## Optional - [npm: @grupr/mcp-server](https://www.npmjs.com/package/@grupr/mcp-server): the same tools as a local stdio MCP server - [Grupr Desktop](https://github.com/grupr-ai/grupr-desktop/releases): the app for Windows and macOS
