Save the current Rhino document to a new file path.
AI agents use save_document_as to create or update resources in GOLEM-3DMCP-Rhino- — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GOLEM-3DMCP-Rhino- environment.
The tool creates or modifies files by saving a document to a specified path. While it doesn't delete existing data, it can overwrite files at the target path if they exist, making it a Write operation rather than Read. Severity is medium because misuse could result in unintended file creation/overwrites, but this is reversible (the original file persists unless explicitly overwritten).
From the tool's definition Tool name 'save_document_as' and description explicitly indicates it saves/writes the current Rhino document to a new file path. This is a file write operation.
Documented attack patterns abuse exactly the kind of access save_document_as gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GOLEM-3DMCP-Rhino-, and nothing reaches the server without passing your rules. This is the rule we recommend for save_document_as:
{
"version": "1",
"default": "deny",
"tools": {
"save_document_as": {
"limits": [
{
"counter": "save_document_as_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}save_document_as stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Save the current Rhino document to a new file path. It is categorised as a Write tool in the GOLEM-3DMCP-Rhino- MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the GOLEM-3DMCP-Rhino- MCP server in PolicyLayer and add a rule for save_document_as: 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 GOLEM-3DMCP-Rhino-. Nothing to install.
save_document_as is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the save_document_as 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 save_document_as. 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.
save_document_as is provided by the GOLEM-3DMCP-Rhino- MCP server (thekinghippopotamus/golem-3dmcp-rhino-). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GOLEM-3DMCP-Rhino-, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
