AI agents call list_items to retrieve information from Kanban without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name 'list_items' unambiguously indicates data retrieval with no side effects. While the description is empty (lowering confidence slightly), the naming convention and server context confirm this is a non-destructive read operation. It follows the pattern of standard list/query tools that retrieve kanban board items without modification.
From the tool's definition Tool name 'list_items' indicates a retrieval operation that queries items from a kanban board database. No description provided, but the name and context (sibling tools include add_*, edit_*, delete_* which are clearly write/destructive operations) indicate…
Documented attack patterns abuse exactly the kind of access list_items gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kanban, and nothing reaches the server without passing your rules. This is the rule we recommend for list_items:
{
"version": "1",
"default": "deny",
"tools": {
"list_items": {}
}
}list_items is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_items. It is categorised as a Read tool in the Kanban MCP Server, which means it retrieves data without modifying state.
Register the Kanban MCP server in PolicyLayer and add a rule for list_items: 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 Kanban. Nothing to install.
list_items 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 list_items 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 list_items. 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.
list_items is provided by the Kanban MCP server (multidimensionalcats/kanban-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kanban, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
