THE RISK

Low Risk

Why start_config_checks needs a policy

Without a description, I can only infer from the tool name. 'start_config_checks' suggests a read/validation operation that checks configuration, which would be low-risk. However, given the server context (Finch MCP for building and pushing container images), it could trigger some external operation. The name suggests a read/diagnostic action, but confidence is very low due to empty description.

From the tool's definition Tool name is 'start_config_checks' but description is empty and uninformative.

POLICY

How to control start_config_checks

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "start_config_checks": {
      "limits": [
        {
          "counter": "start_config_checks_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

start_config_checks gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Finch 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.
