WHAT IT DOES

What search_users does on GitHub

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

RISK

Why search_users is rated Low

This tool retrieves or queries user data from GitHub with no side effects. It matches the 'Read' category definition of search/query operations that do not create, modify, delete, execute code, or commit financial obligations. The blast radius of misuse is minimal—an attacker could enumerate GitHub users but cannot cause damage or unauthorized modifications.

From the tool's definition Tool name 'search_users' combined with description 'Search users' indicates a query operation that retrieves user information without modifying data.

RECOMMENDED RULE

The rule that runs search_users safely

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

search_users Allowed

search_users 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": {
    "search_users": {}
  }
}

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

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