StockUp Quan MCP Server

Financial AI MCP server for Claude Desktop, Cursor, and Model Context Protocol-compatible AI agents.

StockUp Quan MCP gives AI agents finance-native tools for stock research, real-time quote context, SEC filing review, portfolio risk analysis, dollar-cost averaging backtests, market sentiment, market-move explanations, and adversarial research review. It connects local MCP clients to the StockUp Quan financial AI API using a server-side StockUp API key.

What This MCP Server Does

StockUp Quan MCP adds finance-specific tools to your AI coding or research agent. Instead of asking a general chatbot to improvise stock analysis, the agent can call named tools backed by StockUp Quan models, API billing, quote grounding, optional Google Search grounding, optional per-key Finnhub enrichment, and Enterprise attribution.

Primary use cases:

• AI stock research assistants for Claude Desktop, Cursor, and compatible MCP clients
• Real-time stock quote summaries and market context
• Public company comparison workflows
• SEC filing and earnings-quality review
• Market sentiment and catalyst analysis
• Adversarial AI research workflows where Claude challenges Quan's evidence, assumptions, and counter-case
• Portfolio concentration and risk review
• Dollar-cost averaging scenario analysis
• Explanations for stock, ETF, sector, and index moves
• Finance agent workflows that need repeatable tool names instead of free-form prompts
• Enterprise finance copilots with user attribution and governed API keys

Installation

Recommended: NPM

Create a StockUp API key at https://stockup.cc/api?mcp=1&source=mcp-readme, then add this to your MCP client configuration:

{
  "mcpServers": {
    "stockup-quan": {
      "command": "npx",
      "args": ["-y", "@stockup/quan-mcp-server"],
      "env": {
        "STOCKUP_API_KEY": "sk_quan_your_key"
      }
    }
  }
}

Restart your MCP client after saving the configuration.

Hosted Script Fallback

If you prefer to download and run the hosted script:

Account Setup

If you do not have a StockUp API key yet, call the setup_stockup_quan MCP tool or open:

https://stockup.cc/api?mcp=1&source=mcp-setup

The StockUp Developer Console lets you:

• Create and nickname Quan API keys
• View active keys and usage
• See whether a key has been used by an MCP connection
• Review last used dates and MCP request counts
• Add an optional Finnhub key
• Link a Finnhub key to a specific Quan API key

Finnhub keys are optional and opt-in per Quan key. If a Quan key does not have a Finnhub key linked, StockUp Quan will not use Finnhub for that key.

AI Research Debate Workflow

get_quan_research_debate_packet is designed for a two-agent research workflow. Quan is the finance research specialist; Claude, Cursor, or another connected host agent is the independent reviewer. The MCP does not claim the agents agree or run an invisible autonomous conversation. Instead, Quan returns a transparent packet the host agent can inspect and challenge.

The packet includes a conditional claim, verified evidence, assumptions, the strongest counter-case, falsifiers, uncertainty, and 3-6 questions for the host agent. This makes it useful for investment-committee style research, due diligence, SEC filing review, earnings analysis, portfolio-risk reviews, and any workflow where a polished answer should be challenged before it is trusted.

Example request to a connected host agent:

Use get_quan_research_debate_packet to investigate whether NVDA's current setup supports a 12-month bullish thesis. Then independently challenge each assumption, look for contrary evidence, and give me a balanced research conclusion with clear unresolved risks.

The host agent should treat Quan's output as research input, not as a final decision or personalized investment advice.

Enterprise Usage

Enterprise model aliases require an Enterprise API key and user attribution:

{
  "env": {
    "STOCKUP_API_KEY": "sk_quan_enterprise_key",
    "STOCKUP_ENTERPRISE_USER_ID": "enterprise_member_uid"
  }
}

You can also pass enterpriseUserId as a tool argument.

Security

Keep STOCKUP_API_KEY in your MCP client environment. Do not paste StockUp API keys, Finnhub keys, passwords, or private portfolio data into prompts, public repos, browser-side JavaScript, or issue trackers.

StockUp responses are for research and education only. They are not personalized financial advice, investment recommendations, tax advice, legal advice, or a replacement for professional review.
