Detect bugs and logical errors in the provided code.
AI agents call debug_code_tool to retrieve information from FastMCP Boilerplate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool analyzes code to identify bugs and logical errors. This is a read/analysis operation with no side effects — it does not execute code, modify files, or write any data. It only inspects and reports findings on the provided code.
From the tool's definition "Detect bugs and logical errors in the provided code"
Documented attack patterns abuse exactly the kind of access debug_code_tool gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FastMCP Boilerplate, and nothing reaches the server without passing your rules. This is the rule we recommend for debug_code_tool:
{
"version": "1",
"default": "deny",
"tools": {
"debug_code_tool": {}
}
}debug_code_tool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Detect bugs and logical errors in the provided code. It is categorised as a Read tool in the FastMCP Boilerplate MCP Server, which means it retrieves data without modifying state.
Register the FastMCP Boilerplate MCP server in PolicyLayer and add a rule for debug_code_tool: 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 FastMCP Boilerplate. Nothing to install.
debug_code_tool 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 debug_code_tool 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 debug_code_tool. 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.
debug_code_tool is provided by the FastMCP Boilerplate MCP server (rainer85ah/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FastMCP Boilerplate, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
