List members who belong to a specific project
AI agents call list_project_members 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 queries and retrieves project membership information without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that returns data about who belongs to a project. The low severity reflects minimal risk even if misused — an AI agent could retrieve membership lists but cannot alter project structure, delete users, or cause irreversible harm with this tool alone.
From the tool's definition Tool name is 'list_project_members' and description states 'List members who belong to a specific project' — a clear retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List members who belong to a specific project. 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_project_members: 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_project_members 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_project_members 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_project_members. 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_project_members 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.
