Why archimate_save_model needs a policy

This tool saves/persists architecture model data to disk. While saving is reversible (the file can be overwritten or deleted separately), it modifies the filesystem state and commits in-memory model changes to persistent storage. This is a classic Write operation—it creates or modifies data reversibly.

From the tool's definition Tool name 'archimate_save_model' and description 'Save the current model to disk' indicate a persistence operation that writes model data to storage.

POLICY

How to control archimate_save_model

PolicyLayer is an MCP gateway — it sits between your AI agents and ArchiMate MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for archimate_save_model:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "archimate_save_model": {
      "limits": [
        {
          "counter": "archimate_save_model_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

archimate_save_model stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
