Stripe SDK upgrades — check before the agent edits code
Agents love to run npm install stripe or bump @stripe/stripe-js from a blog post. Sometimes the package name is wrong (typosquat). Sometimes the major version breaks your checkout flow.
Zephex gives your agent hosted tools to verify the package and list breaking changes before it touches payment code—the same idea as catching a fake Stripe SDK before install.
Step 1 — Connect Zephex
Use install or the Cursor / Claude Code guide. You need one API key and one MCP config.
Step 2 — Copy these prompts
- “Run check_package on @stripe/stripe-js (or our exact package name). Is this the real package? Any typosquat or registry red flags?”
- “Run audit_package from our current Stripe SDK version to the target version. List breaking API changes, CVEs, and migration steps.”
- “Run scope_task: upgrade Stripe checkout and webhooks—return the smallest set of files to change with risk notes.”
- “Use read_code on the symbols the audit flagged—do not rewrite whole files blindly.”
Why not skip tools and just ask GPT?
General models guess from training data. check_package hits the live npm registry. audit_package compares versions with migration notes. Everyone on the team gets the same checks through one hosted MCP key.
