What recompute_document does on FreeCAD Robust MCP Server
AI agents invoke recompute_document to trigger actions in FreeCAD Robust MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why recompute_document is rated High
Recomputing a document triggers a computation/update operation across all dependent objects in the 3D modeling environment. This is an active execution of FreeCAD's dependency graph resolution, not a simple read or write — it runs an update process whose effects depend on the current state of the document. Misuse could cause unintended cascading changes across a complex model.

Attacks that exploit this kind of access
The rule that runs recompute_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 recompute_document, this is the rule to start with:
recompute_document stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 recompute_document call is checked against it from then on.
Questions about recompute_document
Recompute a FreeCAD document to update all dependent objects. It is categorised as a Execute tool in the FreeCAD Robust MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for recompute_document: 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.
recompute_document is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the recompute_document 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 recompute_document. 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.
recompute_document 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.
