AI agents call list_operators_mcp to retrieve information from Doctah-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and returns game data (operator names) from the Arknights PRTS.wiki database without modifying, deleting, or executing any operations. Fuzzy search is a read-only query operation. No financial transactions, code execution, or data modification occurs. This is a straightforward Read category tool with low severity since it only exposes publicly available game information.
From the tool's definition Tool name 'list_operators_mcp' and description indicate it 'searches related operators and returns operator name list (fuzzy search)'. This is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_operators_mcp gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Doctah-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_operators_mcp:
{
"version": "1",
"default": "deny",
"tools": {
"list_operators_mcp": {}
}
}list_operators_mcp is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Doctah- MCP server in PolicyLayer and add a rule for list_operators_mcp: 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 Doctah-MCP. Nothing to install.
list_operators_mcp 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 list_operators_mcp 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 list_operators_mcp. 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.
list_operators_mcp is provided by the Doctah- MCP server (tonybotni/doctah-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Doctah-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
