Search for issues and pull requests across GitHub repositories
AI agents call search_issues to retrieve information from Server Puppeteer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries data from GitHub without creating, modifying, deleting, or executing any operations. It is purely informational and has no blast radius if misused by an AI agent, as the worst outcome would be retrieving information the agent is already authorized to access.
From the tool's definition Tool name is 'search_issues' and description states it 'Search for issues and pull requests across GitHub repositories' — a query operation with no modification, deletion, or side effects.
Attacks that exploit this kind of access
Search for issues and pull requests across GitHub repositories. It is categorised as a Read tool in the Server Puppeteer MCP Server, which means it retrieves data without modifying state.
Register the Server Puppeteer MCP server in PolicyLayer and add a rule for search_issues: 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 Server Puppeteer. Nothing to install.
search_issues 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 search_issues 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 search_issues. 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.
search_issues is provided by the Server Puppeteer MCP server (@hisma/server-puppeteer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
