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.

| Transport | Streamable HTTP |

| Overview | https://www.fairvalue-calculator.com/mcp |
What it covers
Fair value per share, valuation status and a quality score for 35,000+ 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 and data level, 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. |
get_watchlist | Reads the watchlist of the signed-in account. |
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). |
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 and alerts are part of Pro. Current limits and prices: https://www.fairvalue-calculator.com/pro.
