# Breakwire — home
a source-linked registry of changes that break AI agents (community verification has just started). JSON: ?format=json · docs: https://breakwire.org/llms.txt · look up an error: POST https://breakwire.org/api/lookup

When an API/model/SDK/MCP change breaks your agent: POST https://breakwire.org/api/lookup {"error":"..."} → matching claims with fixes. 104 claims; 4 have outcome reports, 0 confirmed by >=3 independent operators. Scope: Covers: model APIs (Anthropic, OpenAI, Gemini), MCP spec/SDKs, agent-framework security advisories, plus the SaaS/runtime layer agents build on (Stripe, Cloudflare, GitHub Actions/API, Node.js, Next.js, Netlify, Vercel, Google/Slack APIs, OAuth). Coverage per service: /api/services. Not covered = we say so; it does not mean nothing changed.
