POLICY

How to control jrnl MCP Server

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

Rate limit write operations

{
  "set_journal": {
    "limits": [
      {
        "counter": "set_journal_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "analyze_tag_cooccurrence": {
    "limits": [
      {
        "counter": "analyze_tag_cooccurrence_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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