WHAT IT DOES

What STEAMPH does on EngScript Engineering MCP

AI agents call STEAMPH as a supporting operation in EngScript Engineering MCP workflows.

Parameter	Type	Required	Description
`P`	object	Yes	Pressure
`T`	object	Yes	Temperature
`h`	object	Yes	pin-hole D
`Cd`	object	—	Discharge coefficient (default: 0.80)
`M_unit`	string	—	Output mass flow unit

Parameters from the server's own tool schema.

RISK

Why STEAMPH is rated Low

Without any rule in front of it, every call an agent makes to STEAMPH happens silently: no trail, no cap, no way to know it misbehaved until something breaks downstream.

RECOMMENDED RULE

The rule that runs STEAMPH 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 STEAMPH, this is the rule to start with:

STEAMPH Rate-limited

STEAMPH gets a rate cap, and 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 STEAMPH call is checked against it from then on.

FAQ

Questions about STEAMPH

What does the STEAMPH tool do? +

Calculate mass flow from pin-hole on the steam piping. It is categorised as a Other tool in the EngScript Engineering MCP MCP Server, which means it performs auxiliary operations.

What parameters does STEAMPH accept? +

STEAMPH accepts 5 parameters: P, T, h, Cd, M_unit. Required: P, T, h. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on STEAMPH? +

Register the EngScript Engineering MCP server in PolicyLayer and add a rule for STEAMPH: 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.

What risk level is STEAMPH? +

STEAMPH is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit STEAMPH? +

Yes. Add a rate_limit block to the STEAMPH 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 STEAMPH completely? +

Set action: deny in the PolicyLayer policy for STEAMPH. 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 STEAMPH? +

STEAMPH 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.
