AI agents call ifc_get_entity 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 queries and retrieves IFC4.3 specification reference data. It performs a read-only lookup of entity definitions, attributes, inheritance, and rules without modifying any data, executing code, or triggering external operations. The sibling tools (ifc_get_inheritance, ifc_get_propertyset, ifc_search_entity) all follow the same read pattern. No destructive, financial, or executable side effects are possible.
From the tool's definition Tool description states 'Get the complete definition' and 'Returns the entity' — retrieval operations with no modification, creation, deletion, or execution.
Attacks that exploit this kind of access
Get the complete definition of an IFC4.3 entity including attributes, inheritance, WHERE rules, and description. Returns the entity. It is categorised as a Read tool in the Ifc Core MCP Server, which means it retrieves data without modifying state.
Register the Ifc Core MCP server in PolicyLayer and add a rule for ifc_get_entity: 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_entity 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_entity 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_entity. 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_entity 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.
