WHAT IT DOES

What github_list_prs does on Github

AI agents call github_list_prs 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 github_list_prs is rated Low

The 'list' prefix strongly suggests a query operation that retrieves PR data. Even without an explicit description, listing operations are universally non-destructive reads. The sibling tools on this server include destructive actions (archive_repo, cancel_workflow_run) and write operations (batch_commit, close_pr), but github_list_prs appears to be a simple data retrieval.

From the tool's definition Tool name 'github_list_prs' indicates listing/querying pull requests; no description provided, but 'list' is a read-only retrieval operation standard in GitHub APIs that queries data without side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

github_list_prs Allowed

github_list_prs 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": {
    "github_list_prs": {}
  }
}

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 github_list_prs call is checked against it from then on.
