WHAT IT DOES

What search_repositories does on GitHub

AI agents call search_repositories 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_repositories is rated Low

This tool performs repository search, which is a read-only operation that queries and returns information about repositories without side effects. It does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal—an agent could retrieve information about repositories it shouldn't access, but cannot alter data or trigger actions.

From the tool's definition Tool name 'search_repositories' and description 'Search repositories' indicate a query operation that retrieves repository metadata without modifying data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_repositories 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_repositories, this is the rule to start with:

search_repositories Allowed

search_repositories 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": {
    "search_repositories": {}
  }
}

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_repositories call is checked against it from then on.
