MOST DANGEROUS TOOLS

High Risk

The most dangerous Faber MCP Server tools

Execute · High faber_deploy This tool executes a deployment operation on production infrastructure. Execute · High faber_service_restart This tool executes a restart command on production infrastructure services. Execute · High faber_rollback A rollback triggers an external deployment operation that switches the running application to a previous release. Write · High faber_create_database This tool creates database infrastructure (MySQL database and user account), which is a write operation that modifies the server state by adding new resources.

7 of Faber MCP Server's 17 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Faber MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and Faber MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "faber_create_database": {
    "limits": [
      {
        "counter": "faber_create_database_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "faber_app_logs": {
    "limits": [
      {
        "counter": "faber_app_logs_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Faber MCP Server — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
