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 Polling Bias & EV Engine.

  1. 01

    Get market summary

    This capability provides a high-level overview of how much a market's price deviates from current polling data.

  2. 02

    Calculate adjusted probability

    Use this to find a corrected probability by factoring in historical bias and time-based uncertainty.

  3. 03

    Evaluate market opportunity

    This capability calculates the Expected Value (EV) to determine if a specific trade signal is statistically sound.

Real work

What teams actually run

01

Election Trading

An agent compares adjusted candidate probabilities against current market prices to find BUY or SELL signals.

02

Poll Validation

You check if a specific poll is being overvalued or undervalued by the market.

03

Risk Assessment

Your AI client uses uncertainty parameters to build confidence intervals around election outcomes.

04

Market Arbitrage

Identify opportunities where the market price is statistically disconnected from corrected polling data.

One connector, every AI

Polling Bias & EV Engine 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 Polling Bias & EV Engine 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.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Polling Bias & EV Engine, so you can see the experience inside your AI.

It does not authenticate your account with Polling Bias & EV Engine. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Polling Bias & EV Engine owners ask.

  • 01

    How does this MCP handle polling bias?

    It uses historical bias data to adjust raw poll numbers, providing a more accurate probability of the actual outcome.

  • 02

    Can I use this with Claude or Cursor?

    Yes, you can connect this MCP to any MCP-compatible client like Claude, Cursor, or Windsurf.

  • 03

    What is an Expected Value (EV) signal?

    It is a calculation that tells your agent if a market price offers a statistically significant opportunity based on the adjusted probability.

  • 04

    Does this MCP host the data?

    Vinkius hosts and manages the MCP, so you don't need to run it locally or manage credentials yourself.

  • 05

    What kind of data do I need to provide?

    You typically provide raw poll percentages, historical bias figures, time remaining until the event, and current market prices.

  • 06

    How is the adjusted probability calculated?

    The probability is calculated by taking the raw poll, adding the historical bias, and factoring in a time-decay component based on the remaining days until the election and the polling uncertainty.

  • 07

    What constitutes a BUY signal?

    A BUY signal is generated by evaluate_market_opportunity when the calculated Expected Value (EV) exceeds the 0.03 threshold.

  • 08

    Can I use this with Claude Desktop?

    Yes, this MCP server can be connected to Claude Desktop, Cursor, VS Code, Windsurf, and any other MCP-compatible client via Vinkius Edge.
