aci
ACI.dev is the open source tool-calling platform that hooks up 600+ tools into any agentic IDE or custom AI agent through direct function calling or a unified MCP server. The birthplace of VibeOps.
ACI.dev is an open-source tool-calling platform that provides AI agents with access to over 600 integrations through either a unified MCP server or direct SDK function calls. It handles multi-tenant OAuth authentication, permission management, and dynamic tool discovery for services like Google Calendar, Slack, Vercel, Supabase, and Cloudflare. Developers can use the platform to avoid building separate API clients and authentication flows for each service, instead accessing capabilities through the unified MCP server or lightweight Python/TypeScript SDKs. The platform powers "VibeOps" workflows that automate DevOps tasks through agentic IDEs.
