List all models across all workspaces. Filter by state param (PRODUCTION, UNLOCKED, etc). Use modelDetails=true for memory/dates. Returns IDs needed by ID-only tools.
AI agents call show_allmodels to retrieve information from Anaplan MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists model metadata across workspaces with optional filtering and detail levels. It has no side effects—it only queries and returns information to support navigation of the Anaplan model hierarchy. The blast radius of misuse is minimal; an attacker could discover model names and IDs but cannot modify, delete, or execute operations.
From the tool's definition Tool name 'show_allmodels' and description 'List all models' indicates a retrieval operation. The description explicitly states it 'Returns IDs' for use by other tools, confirming read-only behavior with no data modification, deletion, or execution.
Documented attack patterns abuse exactly the kind of access show_allmodels gives an agent:
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 show_allmodels:
{
"version": "1",
"default": "deny",
"tools": {
"show_allmodels": {}
}
}show_allmodels is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all models across all workspaces. Filter by state param (PRODUCTION, UNLOCKED, etc). Use modelDetails=true for memory/dates. Returns IDs needed by ID-only tools. It is categorised as a Read tool in the Anaplan MCP MCP Server, which means it retrieves data without modifying state.
Register the Anaplan MCP server in PolicyLayer and add a rule for show_allmodels: 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.
show_allmodels is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the show_allmodels 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 show_allmodels. 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.
show_allmodels 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.
Start from Anaplan MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
