What get_nonce does on Waiaas
AI agents call get_nonce to retrieve information from Waiaas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_nonce is rated Low
Nonce retrieval is a fundamental read operation in blockchain contexts—it queries transaction state without modifying it. Even in a wallet context, reading nonce values is necessary for constructing transactions but does not itself execute transfers, approve actions, or commit financial transactions. The empty description lowers confidence slightly, but the function name strongly indicates a harmless read operation.
From the tool's definition Tool name 'get_nonce' suggests retrieval of a nonce value (a cryptographic counter used in blockchain transactions). The empty description prevents definitive classification, but nonce retrieval is a read-only operation with no side effects.
Attacks that exploit this kind of access
The rule that runs get_nonce safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Waiaas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_nonce, this is the rule to start with:
get_nonce is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Waiaas, apply this rule, and every get_nonce call is checked against it from then on.
Questions about get_nonce
get_nonce is a read tool on the Waiaas MCP server. It is categorised as a Read tool in the Waiaas MCP Server, which means it retrieves data without modifying state.
Register the Waiaas MCP server in PolicyLayer and add a rule for get_nonce: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Waiaas. Nothing to install.
get_nonce is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_nonce 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.
Set action: deny in the PolicyLayer policy for get_nonce. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_nonce is provided by the Waiaas MCP server (minhoyoo-iotrust/waiaas). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
