What cloudsync_credentials_verify does on Nasbridge
AI agents invoke cloudsync_credentials_verify to trigger actions in Nasbridge. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why cloudsync_credentials_verify is rated High
This tool actively tests/verifies credentials by making a real connection attempt to an external cloud service. It executes an external operation (authentication/connection check) rather than merely reading local data. Misuse could trigger repeated authentication attempts or expose credential validity information to an attacker.

The rule that runs cloudsync_credentials_verify safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nasbridge, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cloudsync_credentials_verify, this is the rule to start with:
cloudsync_credentials_verify stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nasbridge, apply this rule, and every cloudsync_credentials_verify call is checked against it from then on.

cloudsync_credentials_verify is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the cloudsync_credentials_verify rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
