Get comments for an issue, project, initiative, update, or document content
AI agents call linear_getComments 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 existing comments from Linear resources without modifying, deleting, or executing any operations. It is a pure read operation that queries and returns data, fitting squarely in the Read category with minimal security risk.

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_getComments:
{
"version": "1",
"default": "deny",
"tools": {
"linear_getComments": {}
}
}linear_getComments is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
