AI agents call list_domains to retrieve information from Loadbay 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 operation—it retrieves and returns a list of domain categories from the Loadbay catalog. There are no side effects, no data modifications, no code execution, and no financial transactions. The blast radius of misuse is minimal, as an agent cannot cause harm by repeatedly listing domains.
From the tool's definition Tool name 'list_domains' and description 'List the harness domains (categories) in the Loadbay catalog' indicate a retrieval operation that queries and returns categorical metadata without modifying any data.
Attacks that exploit this kind of access
List the harness domains (categories) in the Loadbay catalog. It is categorised as a Read tool in the Loadbay MCP Server, which means it retrieves data without modifying state.
Register the Loadbay MCP server in PolicyLayer and add a rule for list_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 Loadbay. Nothing to install.
list_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_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_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_domains is provided by the Loadbay MCP server (https://loadbay.xyz/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_domains is one line of Loadbay's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
