aci

ACI.dev is an open-source platform for unifying “tool-calling” in agentic IDEs/custom agents. It provides multi-tenant authentication, dynamic tool discovery, and intent/natural-language permission boundaries, exposed either via a unified MCP server (in a separate repo) and/or through SDKs (Python/TypeScript).

Best When

You want a single MCP/SDK layer to connect an LLM agent to many SaaS/tools with centralized OAuth/secrets and fine-grained permissions.

Avoid When

You only need a small number of direct tool integrations and prefer simplest possible auth/API surface over a multi-tenant platform.

Use Cases

  • Connect an AI agent/IDE to many third-party services via a unified tool-calling interface
  • Automate workflows such as devOps, provisioning/deployment, and debugging through tool integrations
  • Build chatbots/assistants that can call external APIs (calendars, messaging, CRM, etc.) with access controls
  • Create research or ops agents that move data between tools (e.g., Notion/Sheets/CRMs)

Not For

  • Serving as a general-purpose internal API gateway without tool-integration needs
  • Use cases requiring strong, verifiable compliance guarantees without reviewing the platform’s actual deployment model and configuration
  • Environments where you cannot run/manage the platform components (backend/front-end) or the MCP server you intend to integrate

Known Gotchas

  • MCP server details appear to be provided in a separate repository (aci-mcp), so integration behavior may differ from the main platform repo’s documentation.
  • Tool discovery/dynamic tool selection can lead to non-deterministic tool lists unless the agent is constrained with explicit permissions or tool sets.
  • Natural-language permission boundaries may require careful prompt/permission configuration to avoid overly broad or overly restrictive actions.
