List comments (notes) on an issue, oldest first.
AI agents call list_issue_notes to retrieve information from GitLab MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing comments on a GitLab issue. It does not create, modify, delete, or execute any operations—it only reads data. The blast radius of misuse is minimal; an agent could only enumerate comments it has access to via the authenticated token, which poses no risk to data integrity or system security.
From the tool's definition Tool name 'list_issue_notes' and description 'List comments (notes) on an issue, oldest first' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List comments (notes) on an issue, oldest first. It is categorised as a Read tool in the GitLab MCP MCP Server, which means it retrieves data without modifying state.
Register the GitLab MCP server in PolicyLayer and add a rule for list_issue_notes: 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 GitLab MCP. Nothing to install.
list_issue_notes 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 list_issue_notes 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 list_issue_notes. 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.
list_issue_notes is provided by the GitLab MCP server (shahabmosavi/gitlab_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
