List tasks of each member as a nested hierarchy: Level 1 Project -> Level 2 Member (assignee) -> Level 3 Status -> Level 4 task list.
AI agents call list_member_tasks to retrieve information from Tonle OpenProject MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation that retrieves and organizes existing project data into a nested hierarchy for display. It has no side effects, does not create, modify, delete, or execute any actions. The listing of tasks by member, project, and status is a standard data retrieval pattern with minimal blast radius if misused—an agent could only retrieve information it is already authorized to access.
From the tool's definition Tool name 'list_member_tasks' and description explicitly states it 'List tasks of each member' - a retrieval operation that presents hierarchical project/member/status/task data with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
List tasks of each member as a nested hierarchy: Level 1 Project -> Level 2 Member (assignee) -> Level 3 Status -> Level 4 task list. It is categorised as a Read tool in the Tonle OpenProject MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tonle OpenProject MCP Server MCP server in PolicyLayer and add a rule for list_member_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 Tonle OpenProject MCP Server. Nothing to install.
list_member_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 list_member_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 list_member_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.
list_member_tasks is provided by the Tonle OpenProject MCP Server MCP server (liratanak/openproject-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
