What is the Put/Call Ratio?

It is a ratio of put option volume or open interest to call option volume or open interest, used to measure market sentiment.

How does this MCP identify market extremes?

It uses statistical capabilities like z-scores and percentile ranks to determine if current PCR values are outliers compared to historical data.

Can I use this with Claude or Cursor?

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

Does this MCP handle both volume and open interest?

Yes, it includes capabilities to calculate PCR for both volume and open interest.

How do I see sentiment trends?

You can use the moving average capability to smooth PCR data and identify the direction of sentiment.

What is the difference between Volume PCR and OI PCR?

Volume PCR measures immediate market activity by comparing put and call volumes, while OI PCR (Open Interest) reflects long-term positioning and total outstanding contracts.

How is sentiment classified?

Sentiment is classified as Bearish if the PCR is greater than 1.0 and Bullish if the PCR is less than 0.7. Values in between are considered Neutral.

Can I use this to find contrarian signals?

Yes. Extreme sentiment values, identified via analyze_sentiment_and_extremes through high percentile ranks or z-scores, often serve as contrarian indicators for market tops or bottoms.

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.

Curated set · 3 capabilities

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Put/Call Ratio Calculator.

01
Calculate moving averages
This capability smooths PCR data to help your agent identify long term sentiment trends. It uses moving averages to filter out daily noise.
02
Calculate pcr metrics
This capability computes the primary volume and open interest PCR values. It provides the foundational ratios needed for sentiment analysis.
03
Analyze sentiment and extremes
This capability determines sentiment classifications and calculates statistical percentile and z-scores. It identifies when current ratios hit extreme levels.

Real work

What teams actually run

Contrarian Signal Hunting

Your agent identifies when PCR reaches a statistical extreme, signaling a potential reversal.

Trend Confirmation

Use moving averages to confirm if a sentiment shift is a real trend or just a spike.

Sentiment Benchmarking

Compare current PCR values against historical series using z-scores.

Data Summarization

Convert large sets of put and call volume into a single sentiment classification.

One connector, every AI

Put/Call Ratio 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.

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

You don't need a client to put Put/Call Ratio Calculator 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.
