List custom domains for a project and show their verification state.
AI agents call list_project_domains to retrieve information from PlugLayer 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 and displays information about custom domains associated with a project. It performs a read-only query operation with no side effects, data modification, code execution, or irreversible actions. The low severity reflects minimal risk even if misused by an agent—reading domain metadata poses no destructive or financial impact.
From the tool's definition Tool name 'list_project_domains' and description 'List custom domains for a project and show their verification state' indicate querying/retrieving domain configuration data with no modification or execution.
Attacks that exploit this kind of access
List custom domains for a project and show their verification state. It is categorised as a Read tool in the PlugLayer MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PlugLayer MCP Server MCP server in PolicyLayer and add a rule for list_project_domains: 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 PlugLayer MCP Server. Nothing to install.
list_project_domains 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_domains 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_domains. 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_domains is provided by the PlugLayer MCP Server MCP server (pluglayer/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
