MOST DANGEROUS TOOLS

High Risk

The most dangerous Capacities MCP Worker tools

Write · Medium capacities_create_object This tool creates new objects in a knowledge management system. Write · Medium capacities_save_to_daily_note This tool modifies data (appends to a daily note) without permanently deleting or overwriting existing content, making it a Write operation. Write · Medium capacities_save_weblink This tool creates new weblink objects in the Capacities knowledge base, which is a reversible write operation.

3 of Capacities MCP Worker's 6 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Capacities MCP Worker

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

Rate limit write operations

{
  "capacities_create_object": {
    "limits": [
      {
        "counter": "capacities_create_object_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "capacities_get_space_info": {
    "limits": [
      {
        "counter": "capacities_get_space_info_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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