列出飞书多维表格的所有字段（列）定义，返回字段 ID、名称、类型等信息
AI agents call list_bitable_fields 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 schema/metadata information about database fields without modifying data, executing code, or triggering external operations. It is a straightforward read operation that queries structure information from a Feishu Bitable table. No data modification, deletion, execution, or financial impact is possible.
From the tool's definition Tool name and description indicate it 'lists' all fields from a Feishu multidimensional table, returning field ID, name, and type information.
Documented attack patterns abuse exactly the kind of access list_bitable_fields 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 list_bitable_fields:
{
"version": "1",
"default": "deny",
"tools": {
"list_bitable_fields": {}
}
}list_bitable_fields 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 list_bitable_fields: 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_bitable_fields 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_bitable_fields 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_bitable_fields. 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_bitable_fields 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.
