Vercel Connect now supports TanStack AI

This is the infrastructure layer maturing. You can now build agents on TanStack AI that call protected APIs through Vercel Connect's OAuth flow, with fresh tokens on every request and consent challenges handled before the model runs. If you're shipping agents that need to hit customer APIs, this removes a whole category of auth complexity you'd otherwise build yourself.

A2M: Trace-Optimized Agent Hijacking in the MCP Ecosystem

This is the first serious published attack on MCP's tool-selection model. The vulnerability is real: agents pick tools by semantic match, not cryptographic trust. If you're deploying MCP agents in production, you need to assume third-party tool servers are adversarial. Immediate action: namespace and vet your tool sources, sandbox tool outputs, and monitor invocation patterns. This will move from research to exploit within months.
