Common questions
Is Fair Value Calculator safe?
It passed 4 of 5 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.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
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.
Is it still maintained?
The GitHub repo last changed 11 days ago, and the latest version (5.2.4) reached the registry 2 days ago.
Which apps can use it?
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 Business and above.
What can I use instead?
In the same category: CCXT, Finance Toolkit, AKQuant

Fair Value Calculator MCP server
Hosted Model Context Protocol server of Fair Value Calculator. It lets an AI assistant look up what a listed stock is worth according to our valuation models, instead of estimating a number from memory.
This repository holds the documentation and the registry manifest (server.json). The server itself is a hosted service; there is nothing to install or run locally, and its source code is not part of this repository.
| Endpoint | https://www.fairvalue-calculator.com/mcp |
| Transport | Streamable HTTP |
| Authentication | OAuth 2.1 with dynamic client registration. A free account is enough. |
| Registry name | com.fairvalue-calculator/fair-value |
| Setup guides | https://www.fairvalue-calculator.com/integrations |
| Overview | https://www.fairvalue-calculator.com/mcp |
What it covers
Fair value per share, valuation status and a quality score for 40,000+ listed stocks worldwide. The fair value is blended from several valuation models on reported fundamentals and is recalculated daily. Method and limits: https://www.fairvalue-calculator.com/methodology.
The numbers are model estimates, not prices and not investment advice. Where the data does not support a figure, the server returns the verdict without a number instead of a weak estimate.
Tools
| Tool | What it does |
|---|---|
resolve_stock | Turns a name, ticker or ISIN into the matching listing, up to five matches. |
get_stock_preview | Verdict, distance to fair value in bands and quality score for one stock, without the exact number. |
get_stock_verdict | Fair value per share with currency, distance to the price, verdict, quality score, data level, uptrend (price one month ago above twelve months ago) and the three buy rules of the strategy (fair value upside of at least 30%, quality score of at least 50, uptrend), with a link to the full analysis. |
compare_stocks | Several stocks side by side with the same values. |
screen_stocks | Stocks matching criteria: minimum distance to fair value, minimum quality, sector, region, uptrend only, or exactly the stocks that meet all three buy rules of the strategy. |
get_watchlist | Reads the watchlist of the signed-in account, each stock with its verdict, uptrend and the three buy rules; for Pro also On track or Review (price at the optimistic fair value, quality dropped clearly, or held for five years). |
add_to_watchlist | Adds a stock to the watchlist. |
remove_from_watchlist | Removes a stock from the watchlist. |
set_watchlist_alerts | Switches the e-mail alerts of the account's watchlist on or off (Pro): an e-mail when a stock changes from On track to Review. |
suggest_watchlist_stocks | Suggests up to eight stocks that fit the saved watchlist: priced below fair value, high quality score, not held yet, stocks with all three buy rules first, ranked with their correlation to the stocks already on it; can also suggest a replacement of similar size for one stock. Changes nothing (Pro, not offered in ChatGPT yet). |
The three tools that change the watchlist or alerts ask for separate consent during sign-in.
Free accounts get the verdict tools with monthly limits; exact fair values for all stocks, comparisons of up to five stocks, alerts and watchlist suggestions are part of Pro. Current limits and prices: https://www.fairvalue-calculator.com/pro.
