Write · Medium capacities_save_to_daily_note This tool creates or modifies data in a reversible manner by appending text to a daily note. Write · Medium capacities_save_weblink This tool creates new data (weblinks) in the user's Capacities space, which is a reversible write operation.

POLICY

How to control Capacities MCP Server

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

Rate limit write operations

{
  "capacities_save_to_daily_note": {
    "limits": [
      {
        "counter": "capacities_save_to_daily_note_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.
