MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Personal Knowledge MCP Server tools

Destructive · High delete_bitable_field Deleting a field/column from a database table is a destructive operation that cannot be easily undone and results in permanent loss of data associated with that field across all records. Destructive · High delete_bitable_records This tool permanently deletes records from a data store (Feishu Bitable/multidimensional tables). Execute · Medium sync_local_documents This tool triggers an active operation — a full re-indexing of local documents. Write · Medium batch_update_bitable_records This tool modifies existing records in a Feishu bitable (multi-dimensional table) without deleting them.

12 of Personal Knowledge MCP Server's 29 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Personal Knowledge MCP Server

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. These are the rules we recommend:

Deny destructive operations

{
  "delete_bitable_field": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "append_sheet_data": {
    "limits": [
      {
        "counter": "append_sheet_data_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "find_similar_pages": {
    "limits": [
      {
        "counter": "find_similar_pages_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Personal Knowledge MCP Server

Can an AI agent delete data through the Personal Knowledge MCP Server MCP server? +

Yes. The Personal Knowledge MCP Server server exposes 2 destructive tools including delete_bitable_field, delete_bitable_records. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Personal Knowledge MCP Server? +

The Personal Knowledge MCP Server server has 9 write tools including append_sheet_data, index_file, batch_update_bitable_records. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Personal Knowledge MCP Server.

How many tools does the Personal Knowledge MCP Server MCP server expose? +

29 tools across 3 categories: Destructive, Read, Write. 17 are read-only. 12 can modify, create, or delete data.

How do I enforce a policy on Personal Knowledge MCP Server? +

Register the Personal Knowledge MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Personal Knowledge MCP Server tool call.

Deterministic rules across all 29 Personal Knowledge MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
