Fair Value Calculator
com.fairvalue-calculatorPublished by fairvalue-calculator.comOfficial publisherv5.2.4Updated Nov 11, 2026
Fair value, quality, uptrend and three buy rules for 40,000+ stocks, plus your watchlist and alerts.
Overview
Hosted MCP server that lets an assistant look up model-based fair value, quality scores and buy-rule verdicts for 40,000+ listed stocks, and manage a watchlist.
- What you can do
- Resolve names, tickers or ISINs to matching listings
- Get fair value, verdict, quality score, uptrend and buy rules for one stock, or a preview without the exact number
- Compare several stocks side by side
- Screen stocks by distance to fair value, quality, sector, region, uptrend or all three buy rules
- Read, add to and remove from the account watchlist, and switch its e-mail alerts on or off
- Suggest watchlist-fitting stocks or a replacement for one holding
- When to use it
- Useful when you want an assistant to answer valuation questions about specific stocks, screen for undervalued or high-quality names, or keep a watchlist updated, instead of estimating numbers from memory.
- Requirements
- Remote Streamable HTTP endpoint; nothing to install locally. Sign-in via OAuth 2.1 with dynamic client registration; a free account is enough, and the three watchlist/alerts tools ask for separate consent during sign-in. Free accounts have monthly limits; exact fair values for all stocks, comparisons of up to five stocks, alerts and suggestions require Pro.
Installation
In SourceWeft
- Open Fair Value Calculator in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.fairvalue-calculator%2Ffair-value/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

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.
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
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.
Connect
In any client that supports remote MCP servers, add the endpoint and sign in when prompted:
Claude Code:
Codex:
Cursor (.cursor/mcp.json):
VS Code: run "MCP: Add Server", choose HTTP and paste the endpoint.
This repository is also a Cursor plugin (plugins/fair-value-calculator), which registers the same endpoint.
Gemini CLI (this repository is also a Gemini CLI extension, gemini-extension.json):
Step-by-step guides for Claude, ChatGPT, Claude Code, Cursor, VS Code and Codex: https://www.fairvalue-calculator.com/integrations.
Example questions
- "What is Apple worth according to Fair Value Calculator?"
- "Which European technology stocks are undervalued right now?"
- "Compare Microsoft, Alphabet and Meta."
- "Add Nestlé to my watchlist."

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
