MOST DANGEROUS TOOLS

High Risk
Write · Medium add_field_value This tool creates or modifies data reversibly—it adds a field value to an existing node. Write · Medium create_checkbox_node This tool creates new nodes (checkbox/task items) in a Tana workspace, which is a reversible modification of data. Write · Medium create_date_node This tool creates new data structures (date nodes) within a Tana workspace. Write · Medium create_field The tool creates new field definitions, which is a write operation that modifies workspace schema but does not delete data or execute arbitrary code.

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

HOW TO CONTROL TANA MCP SERVER

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

Rate limit write operations
{
  "add_field_value": {
    "limits": [
      {
        "counter": "add_field_value_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

  1. Create a free account and register Tana MCP Server — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
