AI agents use openmandate_resend_otp to create or modify resources in OpenMandate. 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 openmandate_resend_otp 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 OpenMandate.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Resend the verification code for a pending contact. Use this if the user didn't receive the code or it expired (codes expire after 10 minutes). Rate limited to 3 per contact per hour.. It is categorised as a Write tool in the OpenMandate MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the OpenMandate MCP server in PolicyLayer and add a rule for openmandate_resend_otp: 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 OpenMandate. Nothing to install.
openmandate_resend_otp 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 openmandate_resend_otp 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 openmandate_resend_otp. 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.
openmandate_resend_otp is provided by the OpenMandate MCP server (https://mcp.openmandate.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
