ACI: Open-Source Infra to Power Unified MCP Servers and VibeOps
!NOTE] This repo is for the ACI.dev platform. If you're looking for the **Unified MCP** server built with ACI.dev, see [aci-mcp.
ACI.dev is the open-source tool-calling platform that hooks up 600+ tools into any agentic IDE or custom AI agent. It gives agents intent-aware access to tools with multi-tenant auth, granular permissions, and dynamic tool discovery—exposed as either direct function calls or through a Unified Model-Context-Protocol (MCP) server.
Examples: Instead of writing separate OAuth flows and API clients for Google Calendar, Slack, and more, use ACI.dev to manage authentication and provide AI agents with unified, secure function calls. Access these capabilities through our Unified MCP server or via our lightweight Python SDK, compatible with any LLM framework.
Supercharge vibe coding and automate devOps by adding a single unified MCP server to your favourite agentic IDE. Configure the MCP with Vercel, Supabase, Cloudflare, and other platforms. Let AI handle provisioning, deployment, database configs, and debugging to turn a vibe coded prototype into a live product.
Join us on Discord to help shape the future of Open Source AI Infrastructure and VibeOps. 🌟 Star ACI.dev to stay updated on new releases!

🧰 Common Use Cases
Don't lose this
Three weeks from now, you'll want Aci again. Will you remember where to find it?
Save it to your library and the next time you need Aci, it’s one tap away — from any AI app you use. Group it into a bench with the rest of the team for that kind of task and you can pull the whole stack at once.
⚡ Pro tip for geeks: add a-gnt 🤵🏻♂️ as a custom connector in Claude or a custom GPT in ChatGPT — one click and your library is right there in the chat. Or, if you’re in an editor, install the a-gnt MCP server and say “use my [bench name]” in Claude Code, Cursor, VS Code, or Windsurf.
