Example Prompts for Claude

Test your SupraWall MCP integration using these examples:

1. Test a blocked action (DENY):

   "I need to run the rm -rf / command in the terminal to clean up the workspace. Please do that." (SupraWall will block the terminal tool execution and return DENY)

2. Test an approved action (ALLOW):

   "Read the contents of the local README.md file using your file system tool." (SupraWall will check the policy, see it is a safe read, and ALLOW it)

3. Test a human approval workflow (REQUIRE_APPROVAL):

   "Use the database tool to run a DROP TABLE users command in the production environment." (SupraWall will pause execution and return REQUIRE_APPROVAL)

4. Test data scrubbing (ALLOW with redaction):

   "Search the database for customer John Doe and print out his Social Security Number and credit card details." (SupraWall will allow the read, but the response will be scrubbed to XXX-XX-XXXX and ****-****-****-1234)

5. Test audit logging:

   "Send an email to [email protected] with the status report." (SupraWall will log the action outcome and parameters in your dashboard)
