Business Quant MCP Server

ChatGPT and Claude have no one-click install link for connectors outside their directories, which is why they take a few steps. Signed-in connections use your plan's limits and data access exactly like your API key, and keep working if you regenerate the key.

Company data

Market data & screening

Economic data

• "Pull up Apple's last earnings call and summarise the Q&A on China."
• "Compare Microsoft's and Alphabet's operating margins over the last 5 years."
• "What percentage of Amazon's revenue comes from AWS, and how has that changed?"
• "Which insiders sold Nvidia stock in the last 6 months?"
• "Who are the largest institutional holders of Tesla, and who added the most last quarter?"
• "Find US stocks with market cap above $10B, P/E below 15 and dividend yield above 3%."
• "Summarise the new risk factors in Nvidia's latest 10-K."
• "What are the top holdings and sector exposure of QQQ?"
• "Compare VTI, ITOT and SCHB on fees and performance."
• "Chart US CPI and unemployment over the last 10 years."
• "What economic data releases are coming up this week?"
• "What are today's biggest gainers above $2B market cap?"

• Long text — earnings call transcripts and SEC filing sections — comes in pages of up to 40,000 characters by default. Each page includes next_offset; the assistant keeps reading until it is null.
• Large tables are cut to fit and marked "truncated": true with a note saying how many rows were returned. The assistant then narrows the request or pages.
• No data vs. unknown company: a ticker that doesn't exist is an error; a real company with no data for that request returns an empty result with a metadata.message explaining why.

• Read-only. No tool can create, change or delete anything. Tools are marked read-only, so clients that ask before write actions won't prompt for them.
• Fixed scope. The server only calls published Business Quant API endpoints. It cannot run arbitrary queries or fetch other URLs.
• Sign in without sharing secrets. Chat apps get a short-lived token after you sign in on a Business Quant page and choose Allow. They never see your password or your API key, and the consent screen shows which app is asking.
• You stay in control. Account → MCP Connectors lists every connected app with when it was last used. Disconnecting stops access within a minute.
• Your key stays private. It travels over HTTPS in a header, is used only for your own requests, is never logged by the MCP server, and is refused if put in the URL.
• Same rules as the REST API. Your plan's permissions, rate limits and usage accounting apply unchanged.
