Get all comments for an issue
AI agents call linear_getComments 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 comments associated with a Linear issue. The verb 'Get' and the absence of any modification language clearly indicate this is a read-only query operation. There are no side effects, no data creation, modification, deletion, or external actions triggered. The severity is low because retrieving comments on project management issues poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'linear_getComments' and description 'Get all comments for an issue' indicates data retrieval with no modification or side effects.
