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.

Curated set · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Efficient Frontier Calculator.

  1. 01

    Calculate tangency portfolio

    This capability finds the tangency portfolio by calculating the maximum Sharpe ratio. It identifies the specific asset weights that provide the best excess return relative to risk.

  2. 02

    Generate frontier samples

    This capability produces a set of data points along the efficient frontier. It allows your agent to trace the curve of optimal risk and return combinations.

  3. 03

    Calculate minimum variance

    This capability identifies the minimum variance portfolio. It calculates the exact asset weights required to achieve the lowest possible volatility for your selection.

Real work

What teams actually run

01

Risk Reduction

Find the minimum variance portfolio to lower the volatility of a two-asset setup.

02

Return Optimization

Identify the tangency portfolio to get the highest possible Sharpe ratio for a given risk-free rate.

03

Portfolio Modeling

Generate frontier samples to visualize the trade-off between risk and return.

04

Small Portfolio Management

Optimize allocations for concentrated holdings of up to five different assets.

Automate a task

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

Efficient Frontier Calculator 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.
