Vercel AI Updates: July 4, 2026

1. Agent Runs Come to the Vercel MCP and CLI

Vercel exposed agent run traces through its MCP server and CLI, adding four MCP tools and matching CLI commands to find projects with agent activity, list recent runs, and retrieve full traces. Each trace includes reasoning, tool calls, and token usage, letting developers and their own agents inspect how deployed agents behaved without leaving the terminal. Source

2. Vercel Sandbox Adds FUSE-Based Filesystems

Vercel Sandbox now supports mounting remote storage and custom filesystems through FUSE, so tools can stream large datasets from object storage and share state across sandboxes without copying data locally. The feature is aimed at agent and code-execution workloads that need to run against remote sources on demand. Source
