Arcade

Arcade is an AI tool-calling platform that provides a runtime environment for AI agents. It facilitates connections with third-party software, managing authentication, tool access, and governance. The platform specifically focuses on AI agent tool calling using the Model Context Protocol (MCP). It operates as an open-source marketplace, offering community-managed connectors for agents to interact with various API endpoints and MCP tools. Arcade provides a pre-built catalog of tools and an SDK for developing custom tools and MCP servers. The platform also includes features for testing and evaluating agent behavior.
