OpenAPI Guard

VS Code

Install OpenAPI Guard from Visual Studio Marketplace. The extension identifier is StackBlender.openapi-guard and it targets desktop VS Code 1.96.0 and later.

Analysis runs automatically in the local workspace. Results appear as diagnostics in the Problems panel, and you can navigate between an OpenAPI operation and its implementation with F12, Ctrl/Cmd+click, or Peek Definition.

The extension also bundles the local CLI, a VS Code agent tool, and the MCP adapter, but installing the extension does not put those on a global path. Use the npm package for terminal or CI use.

Configuration options, behavior details, and troubleshooting are in the public support repository until they move here. Bugs: use the VS Code bug form.
