Arcade.dev

Arcade.dev is an MCP runtime for production AI agents that handles OAuth user authorization, token management, and thousands of authenticated integrations as MCP tools, with hosted and self-hostable deployments.

Arcade.dev is an MCP (Model Context Protocol) runtime built for deploying AI agents into production, where the hard problem is not calling tools but authorizing them safely. The Arcade Engine is a hosted or self-hostable API surface that handles OAuth user authorization, manages per-user tokens, and enforces that an agent acts as a specific authenticated user with only that user's permissions, while leaving a complete audit trail of every action. This user-in-the-loop, on-behalf-of authorization model is Arcade's core differentiator. The platform exposes thousands of pre-built, authenticated integrations as MCP tools that agent frameworks can consume directly, including LangChain, OpenAI Agents, CrewAI, AG2, Google ADK, and the Vercel AI SDK. Rather than each team re-implementing OAuth flows and token management for every SaaS app, Arcade centralizes tool execution, hosting, and governance so agents can reliably and securely act across many services. Arcade supports flexible deployment, including cloud, VPC, on-premises, and air-gapped environments, which suits enterprises with strict security and compliance requirements. The company closed a $60M Series A in June 2026 led by SYN Ventures, with strategic investment from Morgan Stanley and Wipro, bringing total funding to $72M, signaling strong momentum for secure agent tooling infrastructure.
