AI agents call cvat_list_tasks to retrieve information from CVAT 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 task data from CVAT using standard filtering parameters. It has no side effects, does not modify, create, delete, or execute any operations—it only retrieves existing task information. This is a classic Read operation.
From the tool's definition Tool name contains 'list' and description explicitly states it 'List CVAT tasks' with 'filters such as search, status, project_id, assignee, owner, sort, page, and page_size'.
Attacks that exploit this kind of access
List CVAT tasks with official /api/tasks filters such as search, status, project_id, assignee, owner, sort, page, and page_size. It is categorised as a Read tool in the CVAT MCP MCP Server, which means it retrieves data without modifying state.
Register the CVAT MCP server in PolicyLayer and add a rule for cvat_list_tasks: 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 CVAT MCP. Nothing to install.
cvat_list_tasks 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 cvat_list_tasks 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 cvat_list_tasks. 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.
cvat_list_tasks is provided by the CVAT MCP server (jangjs1216/cvat-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
