AI agents call ifc_get_propertyset to retrieve information from Ifc Core without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries IFC specification metadata (PropertySet definitions). It has no side effects, does not modify data, execute code, delete data, or handle financial transactions. It is a straightforward read operation against a static specification reference database.
From the tool's definition Tool description states 'Get or search IFC4.3 PropertySet definitions' — pure retrieval operations with no modification or execution capabilities.

Register the Ifc Core MCP server in PolicyLayer and add a rule for ifc_get_propertyset: 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 Core. Nothing to install.
ifc_get_propertyset 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 ifc_get_propertyset 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 ifc_get_propertyset. 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.
ifc_get_propertyset is provided by the Ifc Core MCP server (shuji-bonji/ifc-core-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
