AI agents call folder-structure to retrieve information from CodeAnalysis MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool almost certainly retrieves and displays directory/file structure information without modifying, executing, or deleting anything. This is a read-only query operation typical of code analysis tools. The sibling tools emphasize analysis over modification, supporting this classification.
From the tool's definition Tool name 'folder-structure' combined with server's purpose of 'code analysis' and sibling tools that include 'analyze-*' and 'build-knowledge-graph' suggests retrieval of repository/file organization metadata. Empty description lowers confidence slightly.
Documented attack patterns abuse exactly the kind of access folder-structure gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CodeAnalysis MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for folder-structure:
{
"version": "1",
"default": "deny",
"tools": {
"folder-structure": {}
}
}folder-structure is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

folder-structure. It is categorised as a Read tool in the CodeAnalysis MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CodeAnalysis MCP Server MCP server in PolicyLayer and add a rule for folder-structure: 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 CodeAnalysis MCP Server. Nothing to install.
folder-structure 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 folder-structure 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 folder-structure. 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.
folder-structure is provided by the CodeAnalysis MCP Server MCP server (0xjcf/mcp_codeanalysis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CodeAnalysis MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
