AI-powered architecture analysis — layers, patterns, and data flow
AI agents call explain_architecture to retrieve information from Trace without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool analyzes and explains architectural patterns and data flows within source code. It retrieves information about code structure and organization but does not execute code, modify files, delete data, or commit financial transactions. The 'analysis' function is purely informational and read-only in nature.
From the tool's definition Tool name 'explain_architecture' and description 'AI-powered architecture analysis — layers, patterns, and data flow' indicate retrieval and analysis of existing code structure with no modification, execution, or deletion of data.
Documented attack patterns abuse exactly the kind of access explain_architecture gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trace, and nothing reaches the server without passing your rules. This is the rule we recommend for explain_architecture:
{
"version": "1",
"default": "deny",
"tools": {
"explain_architecture": {}
}
}explain_architecture is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

AI-powered architecture analysis — layers, patterns, and data flow. It is categorised as a Read tool in the Trace MCP Server, which means it retrieves data without modifying state.
Register the Trace MCP server in PolicyLayer and add a rule for explain_architecture: 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 Trace. Nothing to install.
explain_architecture 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 explain_architecture 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 explain_architecture. 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.
explain_architecture is provided by the Trace MCP server (nikolai-vysotskyi/trace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
