Context

Stripe ships breaking API changes on a release train, and most integrations don't know which release they're really on. Portage answers four questions for the coding agent: which release the code is actually on, which breaking changes touch it (file:line plus changelog), what to write instead, and what proves each change was handled.

What I built

  1. 01

    A read-only MCP server over stdio, in TypeScript with Zod-validated tools, backed by the Stripe CLI's docs.

  2. 02

    A catalogue of 51 stable breaking changes with authored remediation specs, and a verify step that separates new failures from pre-existing ones.

  3. 03

    Validation on four open-source codebases nobody on the team chose (documenso, formbricks, Ghost, cal.com); all 8 defects it surfaced were closed.
