WHAT IT DOES

What add_external_geometry does on FreeCAD Robust MCP Server

AI agents use add_external_geometry 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 add_external_geometry is rated Medium

This tool creates or modifies geometry in FreeCAD sketches by adding external geometry references. While the description is unavailable, the naming pattern and context of sibling tools that perform additive/constructive operations strongly suggest a Write category (reversible modification). It does not execute arbitrary code, delete data, or move financial resources.

From the tool's definition Tool name 'add_external_geometry' indicates creation/addition of geometric elements in FreeCAD; sibling tools like 'add_sketch_line', 'add_sketch_circle', 'add_sketch_constraint' all perform Write operations (creating/modifying sketch geometry).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_external_geometry 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 add_external_geometry, this is the rule to start with:

add_external_geometry Rate-limited

add_external_geometry 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.

The button opens the PolicyLayer dashboard: create your workspace, connect FreeCAD Robust MCP Server, apply this rule, and every add_external_geometry call is checked against it from then on.

FAQ

Questions about add_external_geometry

What does the add_external_geometry tool do? +

add_external_geometry is a write tool on the FreeCAD Robust MCP Server MCP server. It is categorised as a Write tool in the FreeCAD Robust MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_external_geometry? +

Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for add_external_geometry: 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 FreeCAD Robust MCP Server. Nothing to install.

What risk level is add_external_geometry? +

add_external_geometry is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_external_geometry? +

Yes. Add a rate_limit block to the add_external_geometry 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.

How do I block add_external_geometry completely? +

Set action: deny in the PolicyLayer policy for add_external_geometry. 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.

What MCP server provides add_external_geometry? +

add_external_geometry is provided by the FreeCAD Robust MCP Server MCP server (spkane/freecad-addon-robust-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
