WHAT IT DOES

What BALANCE does on EngScript Engineering MCP

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

Parameter	Type	Required	Description
`EQUATION`	object	Yes	Equality/inequality constraints. Keys prefixed eq/ge/le/gt/lt. Each entry: {'left': expr, 'right': expr}.
`MAXIMIZE`	object	—	Objective to maximize. Format: {'left': 'maxtarget', 'right': 'expr'}.
`MINIMIZE`	object	—	Objective to minimize. Format: {'left': 'mintarget', 'right': 'expr'}.
`VARIABLE`	object	Yes	Decision variables. Each entry: [lb, init, ub] for free variable, or [fixed, fixed, fixed] for constant.

Parameters from the server's own tool schema.

RISK

Why BALANCE is rated Low

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

Attacks that exploit this kind of access

RECOMMENDED RULE

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

BALANCE Rate-limited

BALANCE 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 BALANCE call is checked against it from then on.

FAQ

Questions about BALANCE

What does the BALANCE tool do? +

General mass/energy balance solver using GEKKO. It is categorised as a Other tool in the EngScript Engineering MCP MCP Server, which means it performs auxiliary operations.

What parameters does BALANCE accept? +

BALANCE accepts 4 parameters: EQUATION, MAXIMIZE, MINIMIZE, VARIABLE. Required: EQUATION, VARIABLE. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on BALANCE? +

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

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

Can I rate-limit BALANCE? +

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

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

BALANCE 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.
