AI agents call list_chunks to retrieve information from WeKnora MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a query operation to retrieve and display chunks of knowledge without modifying, deleting, or executing any operations. This is a straightforward data retrieval function typical of Read category tools. The low severity reflects minimal risk if an AI agent calls this tool, as it only lists existing data.
From the tool's definition Tool name 'list_chunks' and description 'List chunks of knowledge' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_chunks gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and WeKnora MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_chunks:
{
"version": "1",
"default": "deny",
"tools": {
"list_chunks": {}
}
}list_chunks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List chunks of knowledge. It is categorised as a Read tool in the WeKnora MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WeKnora MCP Server MCP server in PolicyLayer and add a rule for list_chunks: 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 WeKnora MCP Server. Nothing to install.
list_chunks 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_chunks 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_chunks. 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_chunks is provided by the WeKnora MCP Server MCP server (nannaolympicbroadcast/weknoramcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from WeKnora MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
