AI agents invoke compute_kerb_run to trigger processes or run actions in Civilquants. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
compute_kerb_run can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access compute_kerb_run gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Paid tier only. Calling this without an authenticated CivilQuants account returns TIER_INSUFFICIENT — sign up at https://civilquants.com/pricing or use the free-tier alternative compute_cantilever_wall. Linear precast concrete kerb run on concrete bed and haunch over Type 1 (Class 1A) granular sub-base. Emits excavation, sub-base (v8 SHW-class-aware), concrete bed, kerb units to BS EN 1340 / SHW Cl. 1101, concrete haunch to back face, optional channel block, and disposal. Supports HB2/HB1/SP/BN/EF/ER kerb profiles and CS1/CS2/dish channels. All four standards render with type designators (CESMM4 R.7, NRM2 34.10, MMHW 1100, SMM7 Q10). Example params: kerb_length=25 m (1–1000), bed_thickness_mm=150 mm (75–300), bed_extra_each_side_mm=100 mm (0–300). Example call: {"params": {"kerb_length": 25, "bed_thickness_mm": 150, "bed_extra_each_side_mm": 100}, "standard": "MMHW"}. Omitted parameters use sensible engineering defaults. Pass deliverables=["xlsx"] to also receive a one-shot Excel BoQ download URL in the same call.. It is categorised as a Execute tool in the Civilquants MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Civilquants MCP server in PolicyLayer and add a rule for compute_kerb_run: 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 Civilquants. Nothing to install.
compute_kerb_run is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the compute_kerb_run 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 compute_kerb_run. 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.
compute_kerb_run is provided by the Civilquants MCP server (https://api.civilquants.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
