Search for GitHub repositories by query (e.g., 'python machine learning', 'user:microsoft')
AI agents call github_search_repositories to retrieve information from MCP Server App without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only searches and retrieves public GitHub repository metadata based on query parameters. It has no capability to modify repositories, execute code, delete data, or commit financial transactions. The blast radius of misuse is minimal—an agent might return irrelevant or sensitive repository names, but cannot cause harm beyond information disclosure of publicly available data.
From the tool's definition Tool is described as 'Search for GitHub repositories by query' which retrieves repository information without modifying, deleting, or executing operations.
Attacks that exploit this kind of access
Search for GitHub repositories by query (e.g., 'python machine learning', 'user:microsoft'). It is categorised as a Read tool in the MCP Server App MCP Server, which means it retrieves data without modifying state.
Register the MCP Server App MCP server in PolicyLayer and add a rule for github_search_repositories: 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 MCP Server App. Nothing to install.
github_search_repositories 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 github_search_repositories 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 github_search_repositories. 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.
github_search_repositories is provided by the MCP Server App MCP server (ovokpus/mcp-server-app). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
