THE RISK

Critical Risk

Why set_currentperiod needs a policy

The tool modifies the current period setting of a model, and the description explicitly warns of potential data loss if periods are removed as a result. This makes it destructive in nature — the data loss is irreversible. The severity is high because misconfiguring the current period across a model could corrupt or permanently lose time-series data at scale.

From the tool's definition WARNING: may cause data loss if periods are removed

POLICY

How to control set_currentperiod

PolicyLayer is an MCP gateway — it sits between your AI agents and Anaplan MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for set_currentperiod:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "set_currentperiod"
  ]
}

set_currentperiod disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Anaplan MCP — 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 set_currentperiod

What does the set_currentperiod tool do? +

Set current period for a model (WARNING: may cause data loss if periods are removed). Use show_currentperiod to see the current value first. It is categorised as a Destructive tool in the Anaplan MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on set_currentperiod? +

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

What risk level is set_currentperiod? +

set_currentperiod is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit set_currentperiod? +

Yes. Add a rate_limit block to the set_currentperiod 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 set_currentperiod completely? +

Set action: deny in the PolicyLayer policy for set_currentperiod. 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 set_currentperiod? +

set_currentperiod is provided by the Anaplan MCP server (larasrinath/anaplan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Anaplan MCP tool call.

Start from Anaplan MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
