AI agents use issue_hap_authorization to create or modify resources in Nordax AI Entity Network. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call issue_hap_authorization repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Nordax AI Entity Network.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access issue_hap_authorization gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Issue a Human Authorization Protocol (HAP) credential to authorize an AI agent to act on a human's behalf. Creates a W3C Verifiable Credential 2.0 with scoped permissions, time-bounded validity, and a DataIntegrityProof signature. Requires authentication — the authenticated user becomes the credential owner.. It is categorised as a Write tool in the Nordax AI Entity Network MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Nordax AI Entity Network MCP server in PolicyLayer and add a rule for issue_hap_authorization: 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 Nordax AI Entity Network. Nothing to install.
issue_hap_authorization is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the issue_hap_authorization 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 issue_hap_authorization. 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.
issue_hap_authorization is provided by the Nordax AI Entity Network MCP server (https://mcp.nordax.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
