AI agents call get_class_info to retrieve information from C++ MCP Server 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 information about class definitions in a C++ codebase without modifying, executing, or deleting any data. It performs passive introspection of code structure. The blast radius of misuse is minimal—at worst, an agent gains understanding of codebase organization, which poses no security risk compared to write, execute, or destructive operations.
From the tool's definition Tool name 'get_class_info' and description 'Get detailed information about a specific class' indicate a retrieval operation.
Documented attack patterns abuse exactly the kind of access get_class_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and C++ MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_class_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_class_info": {}
}
}get_class_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get detailed information about a specific class. It is categorised as a Read tool in the C++ MCP Server MCP Server, which means it retrieves data without modifying state.
Register the C++ MCP Server MCP server in PolicyLayer and add a rule for get_class_info: 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 C++ MCP Server. Nothing to install.
get_class_info 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 get_class_info 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 get_class_info. 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.
get_class_info is provided by the C++ MCP Server MCP server (kandrwmrtn/cplusplus_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from C++ MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
