MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Kiseki-Labs-Readwise-MCP tools

Destructive · High delete_readwise_tag This tool permanently deletes tag associations from Readwise documents. Write · Medium add_readwise_tag This tool creates or modifies metadata (tags) within Readwise documents. Write · Medium update_readwise_tag This tool creates or modifies tag metadata on Readwise documents reversibly.

3 of Kiseki-Labs-Readwise-MCP's 8 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Kiseki-Labs-Readwise-MCP

PolicyLayer is an MCP gateway — it sits between your AI agents and Kiseki-Labs-Readwise-MCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "delete_readwise_tag": {
    "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

{
  "add_readwise_tag": {
    "limits": [
      {
        "counter": "add_readwise_tag_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "find_readwise_documents_by_names": {
    "limits": [
      {
        "counter": "find_readwise_documents_by_names_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 Kiseki-Labs-Readwise-MCP

Can an AI agent delete data through the Kiseki-Labs-Readwise- MCP server? +

Yes. The Kiseki-Labs-Readwise-MCP server exposes 1 destructive tools including delete_readwise_tag. 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 Kiseki-Labs-Readwise-MCP? +

The Kiseki-Labs-Readwise-MCP server has 2 write tools including add_readwise_tag, update_readwise_tag. 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 Kiseki-Labs-Readwise-MCP.

How many tools does the Kiseki-Labs-Readwise- MCP server expose? +

8 tools across 3 categories: Destructive, Read, Write. 5 are read-only. 3 can modify, create, or delete data.

How do I enforce a policy on Kiseki-Labs-Readwise-MCP? +

Register the Kiseki-Labs-Readwise- 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 Kiseki-Labs-Readwise-MCP tool call.

Deterministic rules across all 8 Kiseki-Labs-Readwise-MCP tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
