WHAT IT DOES

What list_sources does on Crow

AI agents call list_sources to retrieve information from Crow 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_sources is rated Low

This tool retrieves or enumerates available data sources without creating, modifying, deleting, or executing operations. It is a read-only informational query with minimal risk even if misused by an AI agent, as it only exposes the names and availability of government data sources.

From the tool's definition Tool name 'list_sources' and description 'List available government data sources' indicate a query/retrieval operation with no modification, deletion, or execution of code.

RECOMMENDED RULE

The rule that runs list_sources safely

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

list_sources Allowed

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

View as policy code

policy.json

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

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

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