AI agents call find_symbol 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 and queries symbol information from codebases for structural analysis purposes. It has no side effects—it only reads/searches code structure. The empty description slightly lowers confidence, but context from the server purpose and related tools strongly indicates read-only navigation functionality.
From the tool's definition Tool name 'find_symbol' combined with sibling tools 'explore_repo', 'read_interface', and 'what_breaks' that are clearly for code navigation and analysis.
Documented attack patterns abuse exactly the kind of access find_symbol 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 find_symbol:
{
"version": "1",
"default": "deny",
"tools": {
"find_symbol": {}
}
}find_symbol is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

find_symbol. 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 find_symbol: 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.
find_symbol 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 find_symbol 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 find_symbol. 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.
find_symbol 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.
