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

These attack patterns abuse exactly the kind of access propose_booking 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.
Re-validate availability + price for a rental and create a Stripe Checkout URL the user (or the agent itself, if it can pay) can complete to book the product end-to-end. No booking is created until the Stripe payment completes. Use get_quote instead when the human needs to confirm identity / enter delivery details on the web app first.. It is categorised as a Write tool in the Green Gooding MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Green Gooding MCP server in PolicyLayer and add a rule for propose_booking: 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 Green Gooding. Nothing to install.
propose_booking 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 propose_booking 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 propose_booking. 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.
propose_booking is provided by the Green Gooding MCP server (https://mcp.greengooding.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
