List pull requests in a repository
AI agents call gh_pr_list to retrieve information from GitHub CLI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists pull requests from a repository without creating, modifying, deleting, or executing any operations. It is a read-only data retrieval operation with minimal risk if misused, as the worst outcome would be exposure of information already accessible to the authenticated user.
From the tool's definition Tool name 'gh_pr_list' and description 'List pull requests in a repository' indicate a query/retrieval operation with no modification or execution of code.
Attacks that exploit this kind of access
List pull requests in a repository. It is categorised as a Read tool in the GitHub CLI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GitHub CLI MCP Server MCP server in PolicyLayer and add a rule for gh_pr_list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches GitHub CLI MCP Server. Nothing to install.
gh_pr_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the gh_pr_list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gh_pr_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gh_pr_list is provided by the GitHub CLI MCP Server MCP server (munch-group/gh-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
