MOST DANGEROUS TOOLS

High Risk

The most dangerous Jopmcp tools

Write · Medium create_note This tool creates new note records in Joplin, which is a reversible operation (notes can be edited or deleted later). Write · Medium create_notebook This tool creates a new organizational container within Joplin. Write · Medium update_note The tool modifies note data within Joplin but does not delete, execute code, move financial resources, or trigger external operations. Write · Medium update_notebook This tool modifies notebook metadata or properties (title, parent, etc.) in a reversible manner.

4 of Jopmcp's 10 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Jopmcp

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

Rate limit write operations

{
  "create_note": {
    "limits": [
      {
        "counter": "create_note_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "find_notes": {
    "limits": [
      {
        "counter": "find_notes_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Create a free account and register Jopmcp — nothing to install.
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.
