Batch assign IDs for multiple object types
AI agents use batch-assign to create or update resources in AL Object ID Ninja MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AL Object ID Ninja MCP Server environment.
The tool creates or modifies ID assignments for Business Central development objects, which is a reversible write operation. While it could cause development conflicts if misused (assigning IDs that collide with existing ones despite safeguards), the operation is not destructive (IDs can be reassigned) and does not involve code execution, deletion, or financial impact.
From the tool's definition Tool name 'batch-assign' and description 'Batch assign IDs for multiple object types' indicate creation/modification of ID assignments in the AL Object ID system.

Documented attack patterns abuse exactly the kind of access batch-assign gives an agent:
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 batch-assign:
{
"version": "1",
"default": "deny",
"tools": {
"batch-assign": {
"limits": [
{
"counter": "batch-assign_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}batch-assign stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Batch assign IDs for multiple object types. It is categorised as a Write tool in the AL Object ID Ninja MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AL Object ID Ninja MCP Server MCP server in PolicyLayer and add a rule for batch-assign: 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.
batch-assign is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the batch-assign 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 batch-assign. 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.
batch-assign 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.
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.
