WHAT IT DOES

What MIXTURE does on EngScript Engineering MCP

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

Parameter	Type	Required	Description
`P`	object	Yes	Pressure
`T`	object	Yes	Temperature
`HC`	array	Yes	Component list. Supported formulas or names: H2(hydrogen), CH4(methane), C2H2(acetylene), C2H4(ethylene), C2H6(ethane),C3H4(propadiene), C3H6(propene), C3H8(pro
`mole`	array	Yes	Mole fractions or mole amounts corresponding to HC. Automatically normalized.
`H_unit`	string	—	Enthalpy unit
`S_unit`	string	—	Entropy unit
`U_unit`	string	—	Internal energy U unit
`k_unit`	string	—	Thermal conductivity k unit
`Cp_unit`	string	—	Heat capacity Cp unit
`Cv_unit`	string	—	Heat capacity Cv unit
`MW_unit`	string	—	Molecular weight unit
`mu_unit`	string	—	Viscosity mu unit

Parameters from the server's own tool schema.

RISK

Why MIXTURE is rated Low

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

RECOMMENDED RULE

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

MIXTURE Rate-limited

MIXTURE 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 MIXTURE call is checked against it from then on.

FAQ

Questions about MIXTURE

What does the MIXTURE tool do? +

Primary thermodynamic property calculator. Use this tool first for all mixture property calculations. Supports hydrocarbons and non-hydrocarbon chemicals (PR EOS flash calculation). It is categorised as a Other tool in the EngScript Engineering MCP MCP Server, which means it performs auxiliary operations.

What parameters does MIXTURE accept? +

MIXTURE accepts 12 parameters: P, T, HC, mole, H_unit, S_unit, U_unit, k_unit, Cp_unit, Cv_unit, MW_unit, mu_unit. Required: P, T, HC, mole. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on MIXTURE? +

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

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

Can I rate-limit MIXTURE? +

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

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

MIXTURE 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.
