Search GitHub repositories.
AI agents call search_repos to retrieve information from Github Insight without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Searching GitHub repositories is a read-only operation that retrieves information without side effects. It does not create, modify, delete, or execute any actions. The operation is limited to querying publicly available repository metadata.
From the tool's definition Tool name 'search_repos' and description 'Search GitHub repositories' indicate a query/search operation with no modification or deletion of data.
Attacks that exploit this kind of access
Search GitHub repositories. It is categorised as a Read tool in the Github Insight MCP Server, which means it retrieves data without modifying state.
Register the Github Insight MCP server in PolicyLayer and add a rule for search_repos: 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 Insight. Nothing to install.
search_repos 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_repos 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_repos. 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_repos is provided by the Github Insight MCP server (wjddusrb03/github-insight-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
