MCP Tool Reference Low Risk

list_issue_labels

List labels associated with a given team

Part of the Linear MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

WHEN AI AGENTS USE THIS TOOL

AI agents call list_issue_labels to retrieve information from Linear without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.

WHY ENFORCE A POLICY ON LIST_ISSUE_LABELS

Even though list_issue_labels only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

tools:
  list_issue_labels:
    rules:
      - action: allow

FREQUENTLY ASKED QUESTIONS

What does the list_issue_labels tool do?

List labels associated with a given team. It is categorised as a Read tool in the Linear MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_issue_labels?

Add a rule in your Intercept YAML policy under the tools section for list_issue_labels. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Linear MCP server.

What risk level is list_issue_labels?

list_issue_labels is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_issue_labels?

Yes. Add a rate_limit block to the list_issue_labels rule in your Intercept 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.

How do I block list_issue_labels completely?

Set action: deny in the Intercept 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.

What MCP server provides list_issue_labels?

list_issue_labels is provided by the Linear MCP server (linear-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
