Arcade.dev is a platform designed for AI tool calling that empowers AI agents to safely carry out real-world tasks such as sending emails, messaging, updating systems, or activating workflows through integrations authorized by users. Serving as a secure authenticated proxy in line with the OpenAI API specification, Arcade.dev allows models to access various external services, including Gmail, Slack, GitHub, Salesforce, and Notion, through both pre-built connectors and custom tool SDKs while efficiently handling authentication, token management, and security. Developers can utilize a streamlined client interface—arcadepy for Python or arcadejs for JavaScript—that simplifies tool execution and authorization processes without complicating application logic with the need for credentials or API details. The platform is versatile, supporting secure deployments in the cloud, private VPCs, or local environments and features a control plane designed for managing tools, users, permissions, and observability. This comprehensive management system ensures that developers can maintain oversight and control while leveraging the power of AI to automate various tasks effectively.
