AI agents call linear_getIssues to retrieve information from Linear without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data (issues) from Linear without creating, modifying, deleting, or executing any actions. It is a straightforward read operation with minimal security risk even if misused by an AI agent, as it only exposes existing issue data that an authenticated user would have access to.
From the tool's definition Tool name 'linear_getIssues' and description 'Get a list of recent issues from Linear' indicate a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access linear_getIssues gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Linear, and nothing reaches the server without passing your rules. This is the rule we recommend for linear_getIssues:
{
"version": "1",
"default": "deny",
"tools": {
"linear_getIssues": {}
}
}linear_getIssues is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a list of recent issues from Linear. It is categorised as a Read tool in the Linear MCP Server, which means it retrieves data without modifying state.
Register the Linear MCP server in PolicyLayer and add a rule for linear_getIssues: 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. Nothing to install.
linear_getIssues 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 linear_getIssues 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 linear_getIssues. 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.
linear_getIssues is provided by the Linear MCP server (tacticlaunch/mcp-linear). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
