What proxy_list does on Yaver
AI agents call proxy_list to retrieve information from Yaver without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why proxy_list is rated Low
This tool retrieves and displays proxy route information but does not modify, execute, or delete anything. It is a passive informational query. Severity is low because reading proxy configuration details poses minimal risk—an agent listing routes cannot cause harm through the list operation itself, though the information could inform subsequent malicious actions. However, the tool itself is harmless.
From the tool's definition Tool name 'proxy_list' and description 'List all reverse proxy routes' indicate a query/retrieval operation with no side effects. The verb 'list' is a classic read operation that returns information about existing proxy configurations.
Attacks that exploit this kind of access
The rule that runs proxy_list safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Yaver, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For proxy_list, this is the rule to start with:
proxy_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Yaver, apply this rule, and every proxy_list call is checked against it from then on.
Questions about proxy_list
List all reverse proxy routes. It is categorised as a Read tool in the Yaver MCP Server, which means it retrieves data without modifying state.
Register the Yaver MCP server in PolicyLayer and add a rule for proxy_list: 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 Yaver. Nothing to install.
proxy_list 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 proxy_list 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 proxy_list. 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.
proxy_list is provided by the Yaver MCP server (yaver-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
