AI agents call charlotte_find to retrieve information from Charlotte 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 charlotte_find 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 charlotte_find gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Search for elements matching criteria. Filters interactive elements by text, role, type, or spatial proximity. Use the selector parameter to find DOM elements by CSS selector — this reaches elements not in the accessibility tree (custom widgets, non-semantic divs). Selector results return Charlotte element IDs usable with click, hover, drag, etc.. It is categorised as a Read tool in the Charlotte MCP Server, which means it retrieves data without modifying state.
Register the Charlotte MCP server in PolicyLayer and add a rule for charlotte_find: 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 Charlotte. Nothing to install.
charlotte_find 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 charlotte_find 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 charlotte_find. 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.
charlotte_find is provided by the Charlotte MCP server (@ticktockbent/charlotte). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
