While the Open WebUI server context involves administrative APIs, this particular tool is scoped to content retrieval only, making it a Read category risk with low severity. The blast radius of misuse is limited to unauthorized access to file contents already stored in the system.

How to control get_file_content

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_file_content": {}
  }
}

get_file_content is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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