WHAT IT DOES

What list_sources does on Gankdat

AI agents call list_sources to retrieve information from Gankdat 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 informational metadata about available datasets and their parameters. It is purely read-only, has no side effects, does not execute code or commands, and does not modify or delete data. The phrase 'Free to call' further reinforces that it is a safe informational endpoint. No blast radius from misuse.

From the tool's definition Tool name 'list_sources' and description 'Datasets this API serves, with the tool name and filter params for each. Free to call.' indicate a retrieval/query operation that returns metadata about available data sources with no modification or side effects.

RECOMMENDED RULE

The rule that runs list_sources safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Gankdat, 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 Gankdat, apply this rule, and every list_sources call is checked against it from then on.
