Why we included this project

Building an agent that talks to multiple SaaS services usually means writing a separate OAuth flow and API client for each one. ACI.dev collapses that work into a single layer: 600+ integrations exposed as direct function calls or through one Model Context Protocol server you can add to an agentic IDE or custom agent. The platform handles the tedious infrastructure, including multi-tenant authentication, secret storage, granular permissions, and dynamic tool discovery, so the agent only receives the tools it actually needs, which also keeps the context window from ballooning. A natural-language permission model plus tool-use logging makes behavior easier to audit. Teams wiring assistants to calendars and CRMs will save the most time, and the framework-agnostic design slots into existing agent architectures without forcing a new stack.
