Your AI editor just got superpowers for distributed systems design. I've shipped a remote MCP server that connects Claude, Cursor, VS Code, OpenCode, and Windsurf directly to your Cascode account over OAuth 2.1. No API keys. No copy-paste. Just your AI editor talking natively to your diagrams. **What's new in 0.8.0:** **Proper auth, done right** OAuth 2.1 with PKCE and dynamic client registration. Per-user token scoping and audience-bound access tokens mean your diagrams stay yours. **Five MCP tools out of the box** list, get, import, export, and delete diagrams straight from your editor. Ask your AI assistant to pull up your architecture, tweak it, and push it back. **Terraform CloudFormation round-trips** this is the big one. Convert between formats while preserving every node and edge. Infrastructure-as-code finally has a format-agnostic home. **One-click install for Cursor and VS Code** CLI for Claude Code and OpenCode. --- Cascode is an interactive playground for distributed systems build AWS architectures, simulate message flows, inject failures, and develop real production intuition. 0.8.0 is the bridge between visual architecture design and the AI-native workflows engineers actually live in. Try it at cascode.uk would love to hear how you're using it in the comments!

Drag-and-drop real AWS services, wire them together, and simulate live traffic. Then inject faults and watch failures cascade through your architecture in real time. Export to CloudFormation or Terraform with auto-inferred IAM in one click. AI Design Doctor grades your architecture and catches anti-patterns. Collaborate in real time with live cursors. Tackle 10 architecture challenges with automated validation. No AWS account needed. Runs entirely in your browser.
