AI agents invoke tracked_recompute to trigger actions in FreeCAD 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.
A 'recompute' in FreeCAD triggers recalculation of the entire document model, re-evaluating all parametric dependencies and updating shapes. This is an operation that executes FreeCAD's internal computation engine. The 'tracked' prefix suggests it monitors or logs the recompute process.
From the tool's definition Tool name 'tracked_recompute' on a FreeCAD MCP server that provides 'direct interaction with FreeCAD's internal data'; description is empty/uninformative.
Documented attack patterns abuse exactly the kind of access tracked_recompute gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FreeCAD MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for tracked_recompute:
{
"version": "1",
"default": "deny",
"tools": {
"tracked_recompute": {
"limits": [
{
"counter": "tracked_recompute_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}tracked_recompute 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.

tracked_recompute. It is categorised as a Execute tool in the FreeCAD MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the FreeCAD MCP Server MCP server in PolicyLayer and add a rule for tracked_recompute: 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 MCP Server. Nothing to install.
tracked_recompute 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 tracked_recompute 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 tracked_recompute. 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.
tracked_recompute is provided by the FreeCAD MCP Server MCP server (theosib/freecad-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FreeCAD MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
