AI agents call karea_list_resources to retrieve information from Karea without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only retrieval of resources (notes and files) within a project. It does not create, modify, delete, or execute any actions. The low severity reflects minimal risk even if misused by an AI agent, as it only exposes existing data.
From the tool's definition Tool name and description clearly indicate a list/query operation: 'List resources (text notes & files) in a project' — retrieves data with no side effects.
Attacks that exploit this kind of access
List resources (text notes & files) in a project. It is categorised as a Read tool in the Karea MCP Server, which means it retrieves data without modifying state.
Register the Karea MCP server in PolicyLayer and add a rule for karea_list_resources: 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 Karea. Nothing to install.
karea_list_resources 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 karea_list_resources 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 karea_list_resources. 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.
karea_list_resources is provided by the Karea MCP server (starecz/karea-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
