AI agents call find_ifc_function 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.
The naming convention 'find_*' is typical of retrieval operations that locate and return information without modifying state. In the context of an IFC model management server, this most likely queries or retrieves function definitions or metadata. The absence of a description limits confidence, but the pattern aligns with Read operations (search, list, get, fetch).
From the tool's definition Tool name 'find_ifc_function' suggests a search or lookup operation within IFC models. The server context involves 'read, create, and edit IFC models', and this tool appears positioned as a query/discovery function analogous to search operations.
Documented attack patterns abuse exactly the kind of access find_ifc_function 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 find_ifc_function:
{
"version": "1",
"default": "deny",
"tools": {
"find_ifc_function": {}
}
}find_ifc_function is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

find_ifc_function. 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 find_ifc_function: 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.
find_ifc_function 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 find_ifc_function 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 find_ifc_function. 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.
find_ifc_function 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.
