AI agents call get_ui_reference to retrieve information from Proxima without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on naming convention and context within a set of primarily Read and Execute tools on an AI gateway server, 'get_ui_reference' most likely retrieves UI reference documentation or specifications without side effects. No evidence suggests modification, deletion, or external execution.
From the tool's definition Tool name 'get_ui_reference' suggests retrieval of UI documentation or reference material. The pattern matches sibling tools like 'analyze_document' and 'academic_search' which are informational read operations.
Documented attack patterns abuse exactly the kind of access get_ui_reference gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Proxima, and nothing reaches the server without passing your rules. This is the rule we recommend for get_ui_reference:
{
"version": "1",
"default": "deny",
"tools": {
"get_ui_reference": {}
}
}get_ui_reference is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_ui_reference. It is categorised as a Read tool in the Proxima MCP Server, which means it retrieves data without modifying state.
Register the Proxima MCP server in PolicyLayer and add a rule for get_ui_reference: 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 Proxima. Nothing to install.
get_ui_reference 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 get_ui_reference 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 get_ui_reference. 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.
get_ui_reference is provided by the Proxima MCP server (zen4-bit/proxima). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
