Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Free options calculators and the Optionscanner Learn library for any AI assistant. No account.
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.
profit_calculatorPrice 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
what_ifWhat 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 h
list_strategiesThe 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
expected_moveThe 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.
credit_spreadBull 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.
debit_spreadCall 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.
probability_of_profitThe 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.
position_sizeHow 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.
learn_searchFind 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.
learn_readThe 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.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (4.1.3) reached the registry 28 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
