The tool creates or modifies data reversibly by updating project properties. While it changes state, the operation is not destructive (projects are not deleted), not financial, and not executing arbitrary code. Update operations are categorized as Write.

From the tool's definition Tool name is 'openproject-update-project' and description states 'Updates an existing project in OpenProject. Only include fields to be changed.' This is a reversible modification operation.

POLICY

How to control openproject-update-project

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "openproject-update-project": {
      "limits": [
        {
          "counter": "openproject-update-project_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

openproject-update-project 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 OpenProject MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
