Get the review comments on a pull request
AI agents call get_pull_request_comments to retrieve information from Zerops Documentation 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 or queries pull request review comments, which is a read-only operation with no side effects. It does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal since it only exposes comment data that would typically already be visible in the repository.
From the tool's definition Tool name is 'get_pull_request_comments' and description states 'Get the review comments on a pull request' — both indicate retrieval of existing data without modification.
