AI agents call get_versions to retrieve information from APS 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 version metadata for a file or item in Autodesk ACC. It performs no writes, deletions, executions, or financial operations—only information retrieval. The sibling tools (get_hubs, get_project_files, get_projects) are all read operations, further confirming this is a safe query function. Misuse poses minimal risk to system integrity.
From the tool's definition Tool name 'get_versions' and description 'Get version information for a specific item' indicate a retrieval operation.
Documented attack patterns abuse exactly the kind of access get_versions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and APS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_versions:
{
"version": "1",
"default": "deny",
"tools": {
"get_versions": {}
}
}get_versions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get version information for a specific item. It is categorised as a Read tool in the APS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the APS MCP Server MCP server in PolicyLayer and add a rule for get_versions: 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 APS MCP Server. Nothing to install.
get_versions 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_versions 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_versions. 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_versions is provided by the APS MCP Server MCP server (kpphillips/aps-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from APS 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.
