AI agents call get_knowledge 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 retrieves existing knowledge entity details from the WeKnora knowledge management system. No data is created, modified, deleted, or executed. The action is passive information retrieval with no blast radius if misused by an AI agent—at worst, it returns data the agent already has access to.
From the tool's definition Tool name 'get_knowledge' with description 'Get knowledge details' indicates a retrieval operation with no side effects. This is a standard read/query pattern.
Documented attack patterns abuse exactly the kind of access get_knowledge 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 get_knowledge:
{
"version": "1",
"default": "deny",
"tools": {
"get_knowledge": {}
}
}get_knowledge is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get knowledge details. 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 get_knowledge: 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.
get_knowledge 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 get_knowledge 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 get_knowledge. 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.
get_knowledge 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.
