获取飞书知识库中指定文档的内容。只需 node_token（从 wiki URL 中 /wiki/ 后的部分），无需 space_id。返回值包含 space_id 和 has_child，可直接用于后续调用 get_wiki_nodes 展开目录树
AI agents call get_wiki_node_content 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 retrieves document content from a knowledge base using a node_token identifier. It performs no mutations, deletions, or external operations—it simply fetches and returns data. The return values (space_id, has_child) are metadata for subsequent read operations.
From the tool's definition Tool name 'get_wiki_node_content' and description states it '获取飞书知识库中指定文档的内容' (retrieves content from a specified document in Feishu knowledge base). The verb '获取' (get/retrieve) and the read-only nature of fetching document content without modification.
Documented attack patterns abuse exactly the kind of access get_wiki_node_content 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_node_content:
{
"version": "1",
"default": "deny",
"tools": {
"get_wiki_node_content": {}
}
}get_wiki_node_content is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取飞书知识库中指定文档的内容。只需 node_token（从 wiki URL 中 /wiki/ 后的部分），无需 space_id。返回值包含 space_id 和 has_child，可直接用于后续调用 get_wiki_nodes 展开目录树. It is categorised as a Read tool in the Personal Knowledge MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Personal Knowledge MCP Server MCP server in PolicyLayer and add a rule for get_wiki_node_content: 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_node_content 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_node_content 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_node_content. 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_node_content 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.
