AI agents call get_stage_info 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.
This tool retrieves game stage information from the Arknights PRTS.wiki database. Even though it currently returns placeholder data, the intended function is read-only data retrieval with no capability to modify, delete, execute code, or commit financial transactions. Classification as Read is appropriate with low severity due to the harmless nature of querying static game data.
From the tool's definition Tool name 'get_stage_info' and description '获取关卡信息（暂未实现，返回占位符）' (Get stage information - not yet implemented, returns placeholder). The verb 'get' and context within a game data access server indicates retrieval-only functionality.
Documented attack patterns abuse exactly the kind of access get_stage_info 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 get_stage_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_stage_info": {}
}
}get_stage_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
获取关卡信息（暂未实现，返回占位符）. It is categorised as a Read tool in the Doctah-MCP MCP Server, which means it retrieves data without modifying state.
Register the Doctah- MCP server in PolicyLayer and add a rule for get_stage_info: 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.
get_stage_info 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 get_stage_info 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 get_stage_info. 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.
get_stage_info 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.
Free to start. No card required.
