Is this MCP safe to use with untrusted input?

Yes. It uses a custom Lexer and AST parser instead of eval(), making code injection physically impossible.

How does this prevent AI math errors?

Instead of the AI guessing the next number in a sequence, it uses a deterministic parser that follows the strict order of operations.

What math functions are supported?

It supports sqrt, abs, sin, cos, tan, log, exp, round, ceil, and floor.

Does this require external libraries?

No. It uses a zero-dependency architecture for fast, local execution.

Which AI clients can use this?

Any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code can connect to it.

Why not just use the standard JavaScript eval() function?

Using eval() exposes your agentic infrastructure to remote code execution (RCE) vulnerabilities. If a user prompts the AI to evaluate process.exit(), eval() will shut down your server. This MCP parses strings into an Abstract Syntax Tree (AST), making malicious execution impossible.

Does it support complex nested parentheses?

Yes. The recursive descent parser handles infinite levels of nested parentheses, ensuring the core order of operations (PEMDAS) is strictly enforced.

What happens if there's a division by zero?

The math engine intercepts infinite states like Division by Zero or invalid syntax, safely returning a gracefully handled error string rather than crashing the capability.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Capability set01 / 01

01

1 capability in this set.

Part of 1 available through Deterministic Math Expression Evaluator.

01
Evaluate math
This capability uses a strict AST parser to solve string-based math expressions. It prevents your AI client from hallucinating results on complex algebraic problems.

Real work

What teams actually run

Scientific Computing

An agent uses the capability to solve complex physics formulas involving square roots and exponents.

Financial Modeling

A user has an agent calculate compound interest or logarithmic growth rates accurately.

Secure Code Generation

Developers use the MCP to ensure that math logic generated by an AI is actually correct and safe to run.

Automated Data Validation

An agent checks if a set of algebraic transformations matches expected mathematical outcomes.

Automate a task

Put Deterministic Math Expression Evaluator to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Deterministic Math Expression Evaluator works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Deterministic Math Expression Evaluator to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Deterministic Math Expression Evaluator, so you can see the experience inside your AI.

It does not authenticate your account with Deterministic Math Expression Evaluator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
