Search for files in a GitHub repository by name or path pattern
AI agents call search_github_files to retrieve information from Code Search, Read & PR Analysis without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries file metadata (names and paths) from a GitHub repository without creating, modifying, deleting, or executing any code. It has no side effects and is purely informational. The low severity reflects that file discovery is a basic read operation with minimal blast radius even if misused by an AI agent.
From the tool's definition Tool description states 'Search for files in a GitHub repository by name or path pattern'. The verb 'search' and the context of 'file' discovery without modification indicates a read-only operation.
Attacks that exploit this kind of access
Search for files in a GitHub repository by name or path pattern. It is categorised as a Read tool in the Code Search, Read & PR Analysis MCP Server, which means it retrieves data without modifying state.
Register the Code Search, Read & PR Analysis MCP server in PolicyLayer and add a rule for search_github_files: 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 Code Search, Read & PR Analysis. Nothing to install.
search_github_files 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_github_files 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_github_files. 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_github_files is provided by the Code Search, Read & PR Analysis MCP server (tuanpham197/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
