Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 390 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name Optionscanner.

  • Pass
    Lists tools

    tools/list returned 13 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 390 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 390 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    67 of 67 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-11T13:42:42.23012Z, within 180 days.

Capabilities

Tools 13

cash_secured_put

Cash-secured put figures: cash set aside, premium income, breakeven and effective purchase price if assigned, the discount to the stock price, return on the cash, maximum loss, and the model's chance of finishing above the breakeven when implied volatility and days are given.

Discovered
covered_call

Covered call figures for shares already held: premium income, breakeven, maximum profit if the shares are called away, the return if the stock is unchanged and the downside cushion, each for the length of the trade. Says when the strike is below the cost basis, and when no stock price breaks even.

Discovered
credit_spread

Bull put or bear call credit spread figures: width, maximum profit and loss, breakeven, return on risk, credit-to-width, and the model's chance of profit when implied volatility and days are given.

Discovered
debit_spread

Call or put debit spread figures: width, maximum profit and loss, breakeven, reward to risk, debit-to-width, and the model's chance of profit when implied volatility and days are given.

Discovered
expected_move

The one and two standard deviation price ranges the options market is pricing for a stock over a horizon, from the stock price, implied volatility and days ahead.

Discovered
iron_condor

Iron condor figures from the four strikes and the net credit: both wing widths, maximum profit and loss, both breakevens, return on risk, credit-to-width, and the model's chance of profit when implied volatility and days are given. A side the credit covers in full has no breakeven, and the answer says so.

Discovered
learn_read

The full text of one Learn article, glossary term, calculator page or research page by slug, as Markdown with its link. Use learn_search first when the slug is unknown.

Discovered
learn_search

Find the Learn article, glossary term, calculator or research page that answers an options question: strategies, the greeks, implied volatility, IV rank, probability of profit, rolling, assignment, the wheel, screening rules and more. Returns titles, summaries and links.

Discovered
list_strategies

The eleven standard structures the calculator knows (long call and put, covered call, cash-secured put, the four vertical spreads, iron condor, straddle, strangle), each built on an example stock price with its legs, maximum profit and loss, breakevens and chance of profit, with a link to open each one.

Discovered
position_size

How many contracts fit a risk budget: account equity, the percent of it risked per trade, and the worst case per contract give the dollar budget, the contract count and the share of equity at risk.

Discovered
probability_of_profit

The model probability that a stock finishes above or below a price level (a breakeven or a short strike) by a date, from implied volatility, under the lognormal the options market implies.

Discovered
profit_calculator

Price any options trade with up to eight legs: maximum profit and loss, breakevens, net credit or debit, the model's chance of profit at expiration and the expected move. Pass a strategy name (for example iron_condor or bull_put_spread) to build standard legs from the stock price, or pass the legs yourself with strikes and prices. Ask it for the max loss on a spread, the breakeven on a straddle, or the chance a condor finishes profitable. Returns a link that opens the same trade in the Optionscanner calculator.

Discovered
what_if

What a trade is worth if the stock moves, time passes or implied volatility changes: profit or loss on a chosen date at a chosen stock price, the same at expiration, and the change for one more day, one more volatility point and a one dollar move. Use it for questions like what happens to my condor if the stock drops ten percent next week.
