ACI.dev: Open-source tool-calling platform for AI agents

ACI.dev connects 600+ tools to any agentic IDE or custom AI agent via direct function calls or a unified MCP server.

ACI.dev: Open-Source Tool-Calling Platform for AI Agents

ACI.dev is an open-source platform designed to bridge the gap between AI agents and a vast ecosystem of tools. It facilitates seamless integration, enabling AI developers to equip their agents with the capabilities of over 600 pre-built tools. This empowers agents to perform complex tasks by directly calling functions or by leveraging a unified MCP (Multi-Agent Communication Protocol) server. Whether you're building within an agentic IDE or developing custom AI agents, ACI.dev provides a robust framework for enhancing agent functionality and expanding their operational scope.

What ACI.dev Does

ACI.dev acts as a universal connector for AI agents. It abstracts the complexities of tool integration, allowing developers to focus on agent logic rather than the intricacies of API calls or data formatting for individual tools. The platform supports two primary modes of operation: direct function calls to tools and integration via an MCP server. This flexibility ensures compatibility with various agent architectures and development workflows. By providing access to a large and growing library of tools, ACI.dev significantly accelerates the development of sophisticated AI agents capable of real-world problem-solving.
