WHAT IT DOES

What HTRINOUTEFF does on EngScript Engineering MCP

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

Parameter	Type	Required	Description
`HC`	object	Yes	Fuel gas hydrocarbon component list (e.g. ['CH4','C2H6'])
`Tair`	object	Yes	Combustion air temperature
`Trad`	object	Yes	Radiant section outlet temperature
`Tstk`	object	Yes	Stack gas temperature
`exO2`	object	Yes	Excess oxygen in flue gas
`mole`	object	Yes	Fuel gas mole fraction list matching HC order (e.g. [0.9, 0.1])
`Mfuel`	object	Yes	Fuel mass flow rate
`Tfuel`	object	Yes	Fuel temperature
`Mair_unit`	string	—	Output air mass flow rate unit
`Qrad_unit`	string	—	Output radiant section duty unit
`Qconv_unit`	string	—	Output convection section duty unit
`Qduty_unit`	string	—	Output total heat duty unit

Parameters from the server's own tool schema.

RISK

Why HTRINOUTEFF is rated Low

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

RECOMMENDED RULE

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

HTRINOUTEFF Rate-limited

HTRINOUTEFF 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 HTRINOUTEFF call is checked against it from then on.

FAQ

Questions about HTRINOUTEFF

What does the HTRINOUTEFF tool do? +

Calculate fired heater heat duty and efficiency from inlet/outlet conditions and composition. It is categorised as a Other tool in the EngScript Engineering MCP MCP Server, which means it performs auxiliary operations.

What parameters does HTRINOUTEFF accept? +

HTRINOUTEFF accepts 12 parameters: HC, Tair, Trad, Tstk, exO2, mole, Mfuel, Tfuel, Mair_unit, Qrad_unit, Qconv_unit, Qduty_unit. Required: HC, Tair, Trad, Tstk, exO2, mole, Mfuel, Tfuel. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on HTRINOUTEFF? +

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

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

Can I rate-limit HTRINOUTEFF? +

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

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

HTRINOUTEFF 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.
