WHAT IT DOES

What set_selection does on FreeCAD Robust MCP Server

AI agents use set_selection 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 set_selection is rated Medium

Without a description, the name alone indicates state modification rather than pure data retrieval. In a CAD context, changing selection state can influence which objects are targeted by follow-up operations, making it a Write operation. It is not Destructive (selection is reversible), Execute (it doesn't run arbitrary code), or Financial.

From the tool's definition Tool name 'set_selection' indicates modification of FreeCAD's internal selection state. Sibling tools include sketch and geometry manipulation operations (add_sketch_line, add_sketch_circle, add_sketch_constraint, etc.), suggesting this operates within a 3D…

RECOMMENDED RULE

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

set_selection Rate-limited

set_selection 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 set_selection call is checked against it from then on.

FAQ

Questions about set_selection

What does the set_selection tool do? +

set_selection 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 set_selection? +

Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for set_selection: 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 set_selection? +

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

Can I rate-limit set_selection? +

Yes. Add a rate_limit block to the set_selection 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 set_selection completely? +

Set action: deny in the PolicyLayer policy for set_selection. 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 set_selection? +

set_selection 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.
