WHAT IT DOES

What server_exec does on DutyDeck

AI agents call server_exec to retrieve information from DutyDeck without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why server_exec is rated Low

Even though server_exec only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs server_exec safely

PolicyLayer is an MCP gateway: it sits between your AI agents and DutyDeck, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For server_exec, this is the rule to start with:

server_exec Allowed

server_exec is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "server_exec": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect DutyDeck, apply this rule, and every server_exec call is checked against it from then on.

FAQ

Questions about server_exec

What does the server_exec tool do? +

在已连接的服务器上执行一条受范围限制的非交互式命令（不会等待键盘输入）。只读诊断可能自动执行；会修改服务、文件或数据的命令，以及无法判断风险的命令，每次都要单独确认。. It is categorised as a Read tool in the DutyDeck MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on server_exec? +

Register the DutyDeck MCP server in PolicyLayer and add a rule for server_exec: 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 DutyDeck. Nothing to install.

What risk level is server_exec? +

server_exec is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit server_exec? +

Yes. Add a rate_limit block to the server_exec 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.

How do I block server_exec completely? +

Set action: deny in the PolicyLayer policy for server_exec. 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.

What MCP server provides server_exec? +

server_exec is provided by the DutyDeck MCP server (taokoplay/DutyDeck). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
