WHAT IT DOES

What STGEFF does on EngScript Engineering MCP

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

Parameter	Type	Required	Description
`E`	object	Yes	Actual generator output
`M1`	object	Yes	Main steam flow
`M2`	object	—	Extraction steam flow #1
`M3`	object	—	Extraction steam flow #2
`M4`	object	—	Extraction steam flow #3
`M5`	object	—	Extraction steam flow #4
`P1`	object	Yes	Stage pressure #1
`P2`	object	Yes	Stage pressure #2
`P3`	object	—	Stage pressure #3
`P4`	object	—	Stage pressure #4
`P5`	object	—	Stage pressure #5
`T1`	object	Yes	Stage temperature #1

Parameters from the server's own tool schema.

RISK

Why STGEFF is rated Low

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

RECOMMENDED RULE

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

STGEFF Rate-limited

STGEFF gets a rate cap, and everything else on the server is denied unless you say otherwise.

    "STGEFF": {
      "limits": [

SET A RULE FOR THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect EngScript Engineering MCP, apply this rule, and every STGEFF call is checked against it from then on.

FAQ

Questions about STGEFF

What does the STGEFF tool do? +

Calculate multistage steam turbine isentropic efficiency. It is categorised as a Other tool in the EngScript Engineering MCP MCP Server, which means it performs auxiliary operations.

What parameters does STGEFF accept? +

STGEFF accepts 12 parameters: E, M1, M2, M3, M4, M5, P1, P2, P3, P4, P5, T1. Required: E, M1, P1, P2, T1. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on STGEFF? +

Register the EngScript Engineering MCP server in PolicyLayer and add a rule for STGEFF: 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 STGEFF? +

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

Can I rate-limit STGEFF? +

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

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

STGEFF 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.
