WHAT IT DOES

What list_presets does on ContextForge MCP Gateway

AI agents call list_presets to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_presets is rated Low

This tool performs a retrieval operation ('list') that returns metadata about available presets and their schemas. There are no side effects, no data modification, no code execution, and no destructive actions. It is purely informational, making it a Read category tool with low severity since an AI agent misusing it would only retrieve information already available to authorized users.

From the tool's definition Tool name 'list_presets' and description 'List available dataset presets with column definitions' indicate a read-only query operation that retrieves and enumerates existing presets without modifying state.

RECOMMENDED RULE

The rule that runs list_presets safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ContextForge MCP Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_presets, this is the rule to start with:

list_presets Allowed

list_presets is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_presets": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ContextForge MCP Gateway, apply this rule, and every list_presets call is checked against it from then on.
