WHAT IT DOES

What filter_list does on Mcp Anything

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

RISK

Why filter_list is rated Low

This tool queries and returns information about filters on a layer without modifying, deleting, or executing any operations. It is a straightforward read operation that retrieves existing state. The low severity reflects minimal blast radius if an AI agent misuses it—it can only retrieve data about layer filters.

From the tool's definition Tool name 'filter_list' and description 'List filters applied to a specific layer' indicates a retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs filter_list safely

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

filter_list Allowed

filter_list 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": {
    "filter_list": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Anything, apply this rule, and every filter_list call is checked against it from then on.
