Why oca_changelog needs a policy

This tool runs the oca-towncrier CLI tool to generate a changelog file. It executes an external command/process that writes output to files, making it an Execute category (and borderline Write). Since it triggers an external tool execution and produces file artifacts, Execute is the most appropriate category. Severity is medium as misuse could overwrite changelog files, but the blast radius is limited.

POLICY

How to control oca_changelog

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "oca_changelog": {
      "limits": [
        {
          "counter": "oca_changelog_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

oca_changelog stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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