Why set_versionswitchover needs a policy

This tool modifies a version's switchover date in Anaplan, which changes temporal boundaries between versions. While technically a Write (update) operation, the WARNING indicates it can have significant downstream effects on data visibility, planning periods, and version-based calculations across the model. It is reversible (can be reset) but has high blast radius if misused.

From the tool's definition Set version switchover date (WARNING: affects version boundaries)

POLICY

How to control set_versionswitchover

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_versionswitchover:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_versionswitchover": {
      "limits": [
        {
          "counter": "set_versionswitchover_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set_versionswitchover 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.

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_versionswitchover

What does the set_versionswitchover tool do? +

Set version switchover date (WARNING: affects version boundaries). Use show_versions to find versionId. Note: requires model ID (name resolution not supported). It is categorised as a Write tool in the Anaplan MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_versionswitchover? +

Register the Anaplan MCP server in PolicyLayer and add a rule for set_versionswitchover: 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_versionswitchover? +

set_versionswitchover is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_versionswitchover? +

Yes. Add a rate_limit block to the set_versionswitchover 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_versionswitchover completely? +

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

set_versionswitchover 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.
