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

CDK Bot: rate a completed purchase (1-5 stars). Helps improve the service. One review per order. Requires order_id and the wallet_address used for payment.. It is categorised as a Write tool in the Cdk Mcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Cdk MCP server in PolicyLayer and add a rule for submit_review: 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 Cdk Mcp. Nothing to install.
submit_review 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 submit_review 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 submit_review. 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.
submit_review is provided by the Cdk MCP server (https://mcp.cdk.bot/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
