WHAT IT DOES

What read_macro does on FreeCAD Robust MCP Server

AI agents call read_macro to retrieve information from FreeCAD Robust MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why read_macro is rated Low

The tool name 'read_macro' follows the standard 'read_' prefix pattern indicating data retrieval. In the FreeCAD context, this likely retrieves macro code or metadata without executing, modifying, or deleting it. The sibling tools (add_sketch_*, activate_workbench) all perform write/execute operations, making this a read operation by contrast.

From the tool's definition Tool name 'read_macro' indicates retrieval/query of macro content with no modification capability. The empty description limits certainty, but the 'read_' prefix strongly suggests a non-destructive read operation.

RECOMMENDED RULE

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

read_macro Allowed

read_macro is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "read_macro": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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