WHAT IT DOES

What open_document does on FreeCAD Robust MCP Server

AI agents use open_document to create or update resources in FreeCAD Robust MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FreeCAD Robust MCP Server environment.

RISK

Why open_document is rated Medium

The tool name 'open_document' most likely opens a FreeCAD document file, which is primarily a Read/Write operation (loading a file into the application context). However, the description is empty, which reduces confidence. Opening a document could also create a new document state in FreeCAD's working environment, making Write the most appropriate category.

From the tool's definition Tool name 'open_document' and empty description. Opening a document typically loads/reads a file into the application.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs open_document safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FreeCAD Robust MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For open_document, this is the rule to start with:

open_document Rate-limited

open_document 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.
