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.

What it solves

ACI.dev solves the complexity of connecting AI agents to external services. Instead of manually building individual API clients, OAuth flows, and authentication logic for hundreds of different apps, it provides a centralized infrastructure to manage these connections securely.

How it works

It acts as a bridge between your AI agent and over 600 external tools. You can access these tools either through a Unified Model-Context-Protocol (MCP) server or a lightweight Python/TypeScript SDK. The platform handles multi-tenant authentication, secrets management, and dynamic tool discovery, allowing agents to call functions reliably without overwhelming their context windows.

Who it’s for

It is designed for developers building agentic IDEs, custom AI agents, or automation workflows who need a reliable way to give their AI systems secure, permission-controlled access to SaaS platforms like Vercel, Slack, or Google Calendar.

Highlights

  • 600+ pre-built integrations for immediate use.
  • Multi-tenant authentication and secrets management.
  • Framework-agnostic design that works with any LLM architecture.
  • Natural language permission boundaries to control agent capabilities.
  • Full logging of tool-use to monitor agent activity and troubleshoot issues.
