AI agents call get_wiki_nodes to retrieve information from Personal Knowledge MCP Server 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 operation that retrieves and lists document hierarchy/metadata from a knowledge space. It has no side effects on the data—it merely queries and returns node information. There is no capability to create, modify, delete, or execute operations. The 'recursive' parameter simply controls depth of the read, not any write or destructive action.
From the tool's definition The tool retrieves a 'node list' (文档目录) and 'all sub-nodes' from a Feishu knowledge space. The description uses query language ('get', '获取') with a recursive parameter to traverse a directory structure.
Documented attack patterns abuse exactly the kind of access get_wiki_nodes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Personal Knowledge MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_wiki_nodes:
{
"version": "1",
"default": "deny",
"tools": {
"get_wiki_nodes": {}
}
}get_wiki_nodes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Personal Knowledge MCP Server MCP server in PolicyLayer and add a rule for get_wiki_nodes: 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 Personal Knowledge MCP Server. Nothing to install.
get_wiki_nodes 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_wiki_nodes 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_wiki_nodes. 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_wiki_nodes is provided by the Personal Knowledge MCP Server MCP server (kyodule/personal-knowledge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Personal Knowledge 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.
