List available issue labels in a Linear team
AI agents call list_issue_labels to retrieve information from Linear MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing labels without creating, modifying, or deleting data. It follows the standard Read pattern of non-destructive data retrieval (list operation). The low severity reflects that label metadata exposure has minimal blast radius—an AI agent misusing this would merely enumerate harmless organizational metadata.
From the tool's definition Tool name 'list_issue_labels' and description 'List available issue labels in a Linear team' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List available issue labels in a Linear team. It is categorised as a Read tool in the Linear MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Linear MCP Server MCP server in PolicyLayer and add a rule for list_issue_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 Linear MCP Server. Nothing to install.
list_issue_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_issue_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_issue_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_issue_labels is provided by the Linear MCP Server MCP server (sylphxai/linear-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
