ACI.dev

ACI.dev (Aipolabs Agent-Computer Interface) is an open-source tool-calling platform that hooks AI agents into 600+ pre-built tools through direct function calling or a unified Model Context Protocol server. Maintained by Aipotheosis Labs (Aipolabs) under Apache 2.0, ACI provides multi-tenant OAuth2 and API-key authentication, per-project App Configurations, natural-language permission guardrails, OpenAI- and Anthropic-compatible function definitions, Python and TypeScript SDKs, and the unified aci-mcp server with ACI_SEARCH_FUNCTIONS and ACI_EXECUTE_FUNCTION meta-tools. The sister project Gate22 adds an open-source MCP gateway and control plane for governing which tools agents can use, what they can do, and how it is audited.
