AI agents call get_wall_properties to retrieve information from IFC Bonsai MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries property data from wall objects in an IFC model with no side effects. It fits the Read category. Severity is low because querying properties poses minimal risk—even if an agent retrieves sensitive property values, no data is modified, deleted, or executed.
From the tool's definition Tool name is 'get_wall_properties' which indicates a retrieval operation on wall objects within an IFC model. The name structure follows standard getter/query patterns (e.g., 'get_*').
Documented attack patterns abuse exactly the kind of access get_wall_properties gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and IFC Bonsai MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_wall_properties:
{
"version": "1",
"default": "deny",
"tools": {
"get_wall_properties": {}
}
}get_wall_properties is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_wall_properties. It is categorised as a Read tool in the IFC Bonsai MCP MCP Server, which means it retrieves data without modifying state.
Register the IFC Bonsai MCP server in PolicyLayer and add a rule for get_wall_properties: 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 IFC Bonsai MCP. Nothing to install.
get_wall_properties is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_wall_properties 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 get_wall_properties. 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.
get_wall_properties is provided by the IFC Bonsai MCP server (show2instruct/ifc-bonsai-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
