Auto-Deploy from Claude Code / Cursor to Vercel — Three Workflows for the Vercel Agent Skills Era
Until 2025, "edit in Cursor/Claude Code → switch to terminal git push → switch to browser to check Vercel" cost dozens of context switches a day. As of May 2026, Vercel Agent Skills (via MCP), the Claude Code Plugin, and Claude Code GitHub Actions v1.0 collapse "code → build → deploy → preview URL → env management → rollback" into one in-agent flow. This article walks through three implementation approaches: ① git push (5-min setup, 60–90s deploy), ② MCP-Direct (.cursor/mcp.json + slash commands like /deploy, /env, /rollback), ③ GitHub Actions (mention @claude in a PR for auto-fix + preview deploy). It then covers the three preview-environment patterns (A/B compare, permanent staging, password-protected client review) and the four operational pitfalls (env leakage, cost explosion, PR conflicts, missed rollback) — all with working code, grounded in May 2026.
