What the integration can see and where it stops.

Workspace observation and pre-execution control are shown separately.

OBSERVE

Evidence CodeMarine can inspect

  • Local workspace edits and generated files
  • Shell events exposed by the Cursor hook surface
  • Dependency, MCP and project instruction changes
PREVENTIVE PATH

Defined blocking potential

  • Supported local shell and write operations after setup
LIMITS

What you should not assume

  • No live canary means active host invocation is not yet proof-backed
  • Background Agents run remotely and need a future sidecar or gateway
  • Native MCP coverage is expanding

Native controls protect Cursor. CodeMarine protects the shared environment.

Keep provider permissions and sandboxes. Add one deterministic policy around the workspace and the rest of your stack.

NATIVE LAYERProvider permissions and containment

Controls the surfaces and execution modes owned by the provider.

CODEMARINE LAYERCross-provider workspace policy

Secures resulting code, software supply chain and supported actions under one control model.

Install the CodeMarine skills for Cursor.

Install the CodeMarine app first, then add the security skills to Cursor. Hooks and MCP can be enabled separately.

codemarine agents install cursor --skills

The app supplies the scanner. The provider skill or adapter connects it to Cursor.
