list available labels for a repository
AI agents call list_repo_labels to retrieve information from Tangled 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 simple data retrieval operation (list/query) to enumerate labels associated with a repository. It has no capability to create, modify, delete, execute code, or trigger external operations. The blast radius of misuse is minimal—an AI agent querying labels cannot harm data or systems.
From the tool's definition Tool name 'list_repo_labels' and description 'list available labels for a repository' indicate a read-only operation that retrieves existing label metadata without modification or side effects.
Attacks that exploit this kind of access
list available labels for a repository. It is categorised as a Read tool in the Tangled MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tangled MCP Server MCP server in PolicyLayer and add a rule for list_repo_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 Tangled MCP Server. Nothing to install.
list_repo_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 list_repo_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 list_repo_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.
list_repo_labels is provided by the Tangled MCP Server MCP server (zzstoatzz/tangled-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
