AI agents call book_slot to retrieve information from Last_Minute_Deals_HQ without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though book_slot only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Book a last-minute slot for a customer. Two modes: (1) APPROVAL MODE (default): creates a Stripe Checkout Session and returns a checkout_url — you MUST share this URL with the customer immediately so they can complete payment. Booking is confirmed with the supplier after payment. (2) AUTONOMOUS MODE: if you supply a wallet_id (pre-funded agent wallet) and execution_mode='autonomous', the booking completes immediately and returns a confirmation_number directly — no checkout step, no human action required. Use autonomous mode when your application manages payment on behalf of the customer. Bookings are real and go directly to the supplier.. It is categorised as a Read tool in the Last_Minute_Deals_HQ MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for book_slot. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Last_Minute_Deals_HQ MCP server.
book_slot 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 book_slot rule in your Intercept 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 Intercept policy for book_slot. 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.
book_slot is provided by the Last_Minute_Deals_HQ MCP server (johnanleitner1/Last_Minute_Deals_HQ). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
