WHAT IT DOES

What clearpass_write does on Hpe Networking

AI agents use clearpass_write to create or update resources in Hpe Networking, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Hpe Networking environment.

RISK

Why clearpass_write is rated Medium

This tool modifies data in the ClearPass system (HPE's network access control platform). Write operations in security-critical network systems like ClearPass—which manages authentication, authorization, and accounting—carry high severity due to potential impacts on network access policies, user credentials, and security posture.

From the tool's definition Tool name contains 'write' and description explicitly states 'Perform a lab write request to ClearPass'. The phrase 'preview-first guard' indicates safeguards are in place but does not negate the write capability.

RECOMMENDED RULE

The rule that runs clearpass_write safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Hpe Networking, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For clearpass_write, this is the rule to start with:

clearpass_write Rate-limited

clearpass_write stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
