AI agents call rowhint_get_windowless_seats to retrieve information from RowHint 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 rowhint_get_windowless_seats 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.

List all window-position seats that have no actual window on a specific aircraft. These are seats labeled as window seats in airline booking systems but where the fuselage structure blocks the view. Use when someone asks about window seats, specifically wants to avoid windowless positions, or is choosing between window seats.. It is categorised as a Read tool in the RowHint MCP Server, which means it retrieves data without modifying state.
Register the RowHint MCP server in PolicyLayer and add a rule for rowhint_get_windowless_seats: 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 RowHint. Nothing to install.
rowhint_get_windowless_seats 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 rowhint_get_windowless_seats 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 rowhint_get_windowless_seats. 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.
rowhint_get_windowless_seats is provided by the RowHint MCP server (rowhint-ntm5/RowHint). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
