THE RISK

Why start-polling needs a policy

This tool executes a service start operation rather than simply reading or writing static data. While not destructive or financial, it initiates a system process that runs continuously and affects system state. Given the context of Business Central development, incorrect polling could impact resource consumption, team workflows, or IDE/development tool stability, justifying a medium severity rating.

From the tool's definition Tool performs an operational action ('start the polling service') that triggers a real-time background process. The verb 'start' indicates execution of a service operation whose effects are external and ongoing.

Documented attack patterns abuse exactly the kind of access start-polling gives an agent:

POLICY

How to control start-polling

PolicyLayer is an MCP gateway — it sits between your AI agents and AL Object ID Ninja MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for start-polling:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "start-polling": {
      "limits": [
        {
          "counter": "start-polling_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

start-polling stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register AL Object ID Ninja MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about start-polling

What does the start-polling tool do? +

Start the polling service for real-time updates. It is categorised as a Execute tool in the AL Object ID Ninja MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start-polling? +

Register the AL Object ID Ninja MCP Server MCP server in PolicyLayer and add a rule for start-polling: 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 AL Object ID Ninja MCP Server. Nothing to install.

What risk level is start-polling? +

start-polling is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start-polling? +

Yes. Add a rate_limit block to the start-polling 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 start-polling completely? +

Set action: deny in the PolicyLayer policy for start-polling. 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 start-polling? +

start-polling is provided by the AL Object ID Ninja MCP Server MCP server (sshadows/al-objid-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AL Object ID Ninja MCP Server tool call.

Start from AL Object ID Ninja MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
