Why crow_data_case_study_rerender_figures needs a policy

Re-rendering PNG fallbacks is a write/update operation that regenerates and overwrites existing image files for a case study. It modifies stored assets but is reversible in the sense that it can be re-rendered again. It does not delete data or execute arbitrary code, placing it in the Write category.

How to control crow_data_case_study_rerender_figures

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

policy.json

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

crow_data_case_study_rerender_figures 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.

Create a free account and register Crow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
