Introducing MCP Events in Mastra

Mastra adds experimental MCP events: MCP servers can now emit real-time events such as failed deploys, merged pull requests or new signups to connected clients via push, poll or webhook delivery, using defineEvent(), .emit() and .subscribe() without a separate pub/sub service, and agents and workflows can react to them. Requires @mastra/mcp 2.5.0 and @mastra/core 1.79.0.
