AI agents call trade_in_value to retrieve information from Sundr Repair Advisor 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 trade_in_value 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.

USE THIS TOOL WHEN USERS ASK: - "How much is my [device] worth?" - "Trade-in value for [device]" - "What can I get for my old [device]?" - "Sell my [device]" - "Best place to sell [device]" - "Apple trade-in value" - "Carrier trade-in deals" - "How much will [carrier] give me for [device]?" - "Where to sell broken [device]?" - "Cash for [device]" - "Buyback price for [device]" COVERS: iPhones, Samsung phones, Pixels, MacBooks, iPads, Apple Watch, AirPods, gaming consoles. RETURNS: Trade-in values from multiple sources (Apple, carriers, Gazelle, Decluttr), condition-based pricing, and direct sell links.. It is categorised as a Read tool in the Sundr Repair Advisor MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for trade_in_value. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Sundr Repair Advisor MCP server.
trade_in_value 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 trade_in_value 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 trade_in_value. 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.
trade_in_value is provided by the Sundr Repair Advisor MCP server (sundr-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
