Mining project data in Claude and ChatGPT
Connect our MCP server and ask about mining projects in plain English. Your assistant screens projects by NPV, IRR, capex and AISC, pulls a project's full record with its source filing, and shows how a deposit's economics changed from study to study.
https://www.mining-stocks.com/api/mcp/Add it to your app, and the first time it connects, our sign-in page asks for your email. That's all: no password, no payment, and every tool is included.

On claude.ai or in the desktop app, open Customize, then Connectors, and choose Add custom connector. Paste the server address and click Connect. Enter your email on the sign-in page and you're back in Claude, connected. It works on mobile too once it's added.
ChatGPT
In ChatGPT's settings, open Apps, then Advanced settings, and turn on developer mode. Choose Create app, paste the server address, pick OAuth, and sign in with your email when ChatGPT asks. Mention Mining Stocks in your question to use it.

Scripts and clients without sign-in
If your client can't open a sign-in page, use an API key instead and send it in the Authorization header as Bearer YOUR_KEY. It opens the same tools.
Enter your email and your key appears right here, free, with no confirmation step. By getting a key, you agree to receive marketing emails from Mining Stocks; you can unsubscribe at any time.
What your assistant can do with it
Five read-only tools over every project we track. Figures come from the companies' own technical reports (NI 43-101, JORC, S-K 1300), are checked by rule-based validation, converted to USD at each study's own exchange rate, and refreshed daily.
- screen_projects
- Shortlist projects by commodity, study type, location, NPV, IRR, initial capex or AISC, sorted the way you ask. Up to 25 projects per call, with paging.
- get_project
- One project's full record: economics as stated and in USD, physical parameters, the validation result, and the source filing with a supporting quote.
- get_study_history
- How a deposit's NPV, IRR and capex changed from one study to the next, from resource estimate to feasibility study.
- get_company
- A company's listings, latest share price, market cap and dividend yield, and every project we extracted for it.
- dataset_stats
- What the data covers, how fresh it is and how it is made.
Things to ask
- “Which gold feasibility studies show a post-tax IRR above 40%?”
- “Which copper projects have the lowest initial capex?”
- “How did the NPV of Freeport's Grasberg district change across its studies?”
- “Compare B2Gold's projects by NPV, capex and payback, with sources.”
What signing in means
The sign-in asks for one thing: your email address. Signing in puts you on our email list, which includes marketing emails about new studies and our offers. Every email has an unsubscribe link, and unsubscribing doesn't disconnect the server.
We store your email, which app you connected (for example Claude or ChatGPT), and when and how often it calls the server. We don't store your questions, your conversations or the requests your assistant sends. The server is read-only: it can't change anything in your account or anywhere else.
To have your data deleted, email miningstockscom@gmail.com. The details are in our privacy policy.
