Get a list of all FDS computational meshes.
AI agents call bulc_list_meshes to retrieve information from BULC Building Designer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about existing meshes without creating, modifying, deleting, or executing any operations. It is a straightforward read-only information retrieval function with minimal risk if misused by an AI agent.
From the tool's definition Tool name includes 'list' and description states 'Get a list of all FDS computational meshes' — a pure retrieval operation with no modification, deletion, or execution of external processes.
Attacks that exploit this kind of access
Get a list of all FDS computational meshes. It is categorised as a Read tool in the BULC Building Designer MCP Server, which means it retrieves data without modifying state.
Register the BULC Building Designer MCP server in PolicyLayer and add a rule for bulc_list_meshes: 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 BULC Building Designer. Nothing to install.
bulc_list_meshes 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 bulc_list_meshes 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 bulc_list_meshes. 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.
bulc_list_meshes is provided by the BULC Building Designer MCP server (using76/bulc_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
