VENTURIGAS
Gas Venturi tube sizing / differential pressure / flow rate calculation based on ISO 5167 Venturi meter (as cast convergent venturi tube). Exactly ONE of [M, dP, D2] must be set to '?' — that variable will be calculated.

What VENTURIGAS does on EngScript Engineering MCP
AI agents use VENTURIGAS to create or update resources in EngScript Engineering MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your EngScript Engineering MCP environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
M | object | Yes | Gas mass flow rate. Set value='?' to calculate. |
k | object | — | Heat capacity ratio (Cp/Cv), default 1.4 |
D1 | object | Yes | Pipe inside diameter |
D2 | object | Yes | Venturi throat diameter. Set value='?' to calculate. |
P1 | object | Yes | Upstream (operating) pressure |
dP | object | Yes | Differential pressure across Venturi meter. Set value='?' to calculate. |
mu | object | Yes | Dynamic viscosity |
rho | object | Yes | Fluid density |

Why VENTURIGAS is rated Medium
An AI agent can call VENTURIGAS faster than any human can review: one bad instruction and it creates or modifies resources in EngScript Engineering MCP by the hundred, each call as confident as the last.

The rule that runs VENTURIGAS safely
PolicyLayer is an MCP gateway: it sits between your AI agents and EngScript Engineering MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For VENTURIGAS, this is the rule to start with:
VENTURIGAS 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.
The button opens the PolicyLayer dashboard: create your workspace, connect EngScript Engineering MCP, apply this rule, and every VENTURIGAS call is checked against it from then on.
Questions about VENTURIGAS
Gas Venturi tube sizing / differential pressure / flow rate calculation based on ISO 5167 Venturi meter (as cast convergent venturi tube). Exactly ONE of [M, dP, D2] must be set to '?' — that variable will be calculated. It is categorised as a Write tool in the EngScript Engineering MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
VENTURIGAS accepts 8 parameters: M, k, D1, D2, P1, dP, mu, rho. Required: M, D1, D2, P1, dP, mu, rho. The full parameter table on this page comes from the server's own tool schema.
Register the EngScript Engineering MCP server in PolicyLayer and add a rule for VENTURIGAS: 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 EngScript Engineering MCP. Nothing to install.
VENTURIGAS is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the VENTURIGAS 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 VENTURIGAS. 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.
VENTURIGAS is provided by the EngScript Engineering MCP server (https://engscript.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
