AI agents call read_interface to retrieve information from XRAY MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves interface definitions or structure information from a codebase for analysis purposes. The server's purpose is code mapping and symbol search—operations that examine but do not alter code. No evidence suggests data modification, deletion, command execution, or financial operations.
From the tool's definition Tool name 'read_interface' and server description indicate structural code analysis operations. The sibling tools (explore_repo, find_symbol, what_breaks) are all read-only operations for code navigation and analysis.
Documented attack patterns abuse exactly the kind of access read_interface gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and XRAY MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for read_interface:
{
"version": "1",
"default": "deny",
"tools": {
"read_interface": {}
}
}read_interface is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

read_interface. It is categorised as a Read tool in the XRAY MCP MCP Server, which means it retrieves data without modifying state.
Register the XRAY MCP server in PolicyLayer and add a rule for read_interface: 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 XRAY MCP. Nothing to install.
read_interface 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 read_interface 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 read_interface. 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.
read_interface is provided by the XRAY MCP server (srijanshukla18/xray). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
