AI agents call d_check_last_version to retrieve information from Smart Coding MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information from public package registries without creating, modifying, deleting, or executing any code. It is purely informational—querying version metadata. While it makes network requests to external services, the action itself is a benign lookup operation with minimal blast radius if misused by an AI agent (worst case: unnecessary network calls or informational inaccuracy).
From the tool's definition Tool description states it 'Get the latest version of a library/package from its official registry' and 'Returns the version string'.
Documented attack patterns abuse exactly the kind of access d_check_last_version gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Smart Coding MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for d_check_last_version:
{
"version": "1",
"default": "deny",
"tools": {
"d_check_last_version": {}
}
}d_check_last_version is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns the version string to help you avoid using outdated dependencies. It is categorised as a Read tool in the Smart Coding MCP MCP Server, which means it retrieves data without modifying state.
Register the Smart Coding MCP server in PolicyLayer and add a rule for d_check_last_version: 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 Smart Coding MCP. Nothing to install.
d_check_last_version 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 d_check_last_version 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 d_check_last_version. 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.
d_check_last_version is provided by the Smart Coding MCP server (omar-haris/smart-coding-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
