WHAT IT DOES

What bulc_set_fire_coupling does on BULC Building Designer

AI agents use bulc_set_fire_coupling to create or update resources in BULC Building Designer — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your BULC Building Designer environment.

WHY IT NEEDS A POLICY

Why bulc_set_fire_coupling needs a policy

The tool configures integration settings between FDS (fire dynamics simulator) and EVAC (evacuation simulator) components. This is a write operation: it modifies simulation parameters that control coupling behavior. It is reversible (configuration can be changed again), so not Destructive. It does not execute simulations (that would be Execute), nor does it move money or delete data.

From the tool's definition Tool name 'bulc_set_fire_coupling' and description 'Configure fire-evacuation coupling for FDS+EVAC integration' indicate this modifies simulation parameters that affect how fire and evacuation models interact—a reversible configuration change.

Verdict

bulc_set_fire_coupling Rate-limited

bulc_set_fire_coupling stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about bulc_set_fire_coupling

What does the bulc_set_fire_coupling tool do? +

Configure fire-evacuation coupling for FDS+EVAC integration. It is categorised as a Write tool in the BULC Building Designer MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on bulc_set_fire_coupling? +

Register the BULC Building Designer MCP server in PolicyLayer and add a rule for bulc_set_fire_coupling: 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.

What risk level is bulc_set_fire_coupling? +

bulc_set_fire_coupling is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit bulc_set_fire_coupling? +

Yes. Add a rate_limit block to the bulc_set_fire_coupling 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.

How do I block bulc_set_fire_coupling completely? +

Set action: deny in the PolicyLayer policy for bulc_set_fire_coupling. 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.

What MCP server provides bulc_set_fire_coupling? +

bulc_set_fire_coupling 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.
