列出当前应用可访问的所有飞书知识空间。用于发现可用的知识空间及其 space_id
AI agents call list_wiki_spaces 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 only retrieves metadata about available knowledge spaces and returns their identifiers (space_id). It performs no write operations, does not execute code or commands, does not delete data, and does not involve financial transactions. It is a straightforward query operation that lists resources, which is characteristic of the Read category.
From the tool's definition Tool name 'list_wiki_spaces' and description '列出当前应用可访问的所有飞书知识空间' (list all Feishu wiki spaces accessible to the current application) indicate a simple enumeration/discovery operation with no data modification or side effects.

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 list_wiki_spaces:
{
"version": "1",
"default": "deny",
"tools": {
"list_wiki_spaces": {}
}
}list_wiki_spaces is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

列出当前应用可访问的所有飞书知识空间。用于发现可用的知识空间及其 space_id. 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 list_wiki_spaces: 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.
list_wiki_spaces 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_wiki_spaces 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_wiki_spaces. 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_wiki_spaces 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.
