The Model Context Protocol (MCP) was developed as an open standard for connecting AI agents to external tools and data sources. Instead of every agent and every tool negotiating their own bespoke integration, MCP provides a shared protocol that any compliant client and server can use to discover tools, share context, and coordinate action. This protocol is the critical foundation that Arcade.dev contributes to, and builds on, to enable agents to touch real users and systems.
Since the initial MCP release in November, 2024, tracked MCP servers have gone from a few hundred to 10,000-plus, with over 97 million monthly downloads of the official SDK and growth accelerating.
In response to the evolution from early-stage prototyping to enterprise production, on July 28, 2026, MCP shipped the largest revision to its spec since launch. Arcade is your guide through all of it: what's new, what's changing, what breaks, and how to migrate efficiently and effectively.
