AI agents call lqwd_check_balance to retrieve information from LQWD Gateway 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 lqwd_check_balance 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.

These attack patterns abuse exactly the kind of access lqwd_check_balance gives an agent. Each links to the full case and the policy that stops it:

Check your LQWD agent account profile. Returns your account tier, status, and registration date. Always free. Authenticate by sending the HTTP header Authorization: Bearer <your_api_key> on MCP requests (where <your_api_key> is the lqwd_... key returned by lqwd_register).. It is categorised as a Read tool in the LQWD Gateway MCP Server, which means it retrieves data without modifying state.
Register the LQWD Gateway MCP server in PolicyLayer and add a rule for lqwd_check_balance: 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 LQWD Gateway. Nothing to install.
lqwd_check_balance 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 lqwd_check_balance 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 lqwd_check_balance. 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.
lqwd_check_balance is provided by the LQWD Gateway MCP server (https://api.lqwdclaw.bot/v1/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
