Search labels in a repository
AI agents call search_labels to retrieve information from Github MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only search operation to discover and list labels within a repository. It retrieves information without side effects, altering data, executing code, or affecting external systems. The limited scope (label metadata only) and query-only nature result in low severity if misused.
From the tool's definition Tool name 'search_labels' and description 'Search labels in a repository' indicate a query/search operation that retrieves label metadata without modifying or executing any operations.
Attacks that exploit this kind of access
Search labels in a repository. It is categorised as a Read tool in the Github MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Github MCP Server MCP server in PolicyLayer and add a rule for search_labels: 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 MCP Server. Nothing to install.
search_labels 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_labels 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_labels. 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_labels is provided by the Github MCP Server MCP server (parassolanki/github-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
