What is ACI.dev?
Building AI agents that interact reliably with real-world applications often means getting bogged down in complex infrastructure tasks. Setting up authentication, managing API clients for numerous services, and ensuring secure, permissioned access can divert significant time and resources from developing your agent's core intelligence. ACI.dev provides the open-source infrastructure layer to handle these challenges, letting you connect your agents to a vast ecosystem of tools securely and efficiently. Think of it as the essential plumbing that empowers your agents to act, without you having to build it all from scratch.
Key Capabilities
🔌 Access 600+ Pre-built Integrations: Connect your agents to popular services like Google Workspace, Slack, Zendesk, Notion, and hundreds more, often in minutes, drastically reducing integration development time.
🔑 Manage Multi-tenant Authentication: Implement secure connections for multiple end-users to various services using built-in OAuth flows and robust secrets management, handling the complexities of user-specific permissions.
📞 Choose Flexible Access Methods: Interact with tools via direct function calling using our lightweight Python SDK (compatible with LangChain, LlamaIndex, or any custom agent framework) or leverage our unified Model-Context-Protocol (MCP) server for a standardized interface.
🛡️ Enhance Agent Reliability & Security: Define natural language permission boundaries to prevent agents from performing unintended actions and utilize dynamic tool discovery to find the right API without overloading the LLM's context window.
🌐 Maintain Framework & Model Agnosticism: Integrate ACI.dev seamlessly into your existing stack. It's designed to work with any LLM and agent architecture, offering flexibility without vendor lock-in.
🔓 Leverage 100% Open Source: Benefit from a fully open-source platform (Apache 2.0 licensed), including the backend, developer portal, and all integrations. Contribute, inspect, and deploy with confidence.
Practical Applications: Building Capable Agents
ACI.dev provides the foundation for a wide range of sophisticated AI agent applications:
Develop Advanced Personal Assistants: Equip chatbots with the ability to manage user calendars (Google Calendar, Outlook), send emails (Gmail), draft messages (Slack), search the web, and interact with various SaaS tools, all authenticated securely for each user.
Construct Automated Research Agents: Build agents that gather information from specified sources, synthesize findings, and automatically sync structured results to platforms like Notion or Google Sheets, streamlining data collection and reporting workflows.
Create Efficient Customer Support Agents: Design agents capable of understanding customer queries, retrieving information from knowledge bases (Zendesk, Salesforce), managing support tickets, and performing specific actions based on authenticated user context.
Why Choose ACI.dev?
ACI.dev directly addresses critical infrastructure hurdles faced when building production-grade AI agents:
Solve Authentication Scalability: Securely manage connections for numerous users across multiple external services without building custom auth logic for each one.
Enable Smart Tool Discovery: Allow agents to dynamically identify and utilize relevant tools without overwhelming LLM context limits, improving performance and accuracy.
Implement Granular Control: Use intuitive, natural language instructions to set precise boundaries on agent actions, enhancing safety and reliability.
Build with Freedom: Adopt an open-source, framework-agnostic solution that prevents vendor lock-in and integrates smoothly with your preferred development tools.
Focus on innovating your AI agent's capabilities, knowing the complex tool integration infrastructure is handled.
