Stock MCP Query

Query historical stock market data including daily OHLCV, financial reports, index data, ETF data, and more through the MCP protocol.

Prerequisites

This skill requires:

1. STOCK_MCP_TOKEN environment variable — a JWT token purchased from the management platform (nps_enhanced)
2. STOCK_MCP_SERVER_URL environment variable (optional) — the MCP server URL, defaults to the URL provided at purchase time

Setup Check

Before using any data query tools, verify the environment is configured:

# Check if token exists
echo ${STOCK_MCP_TOKEN:+Token is set}${STOCK_MCP_TOKEN:-ERROR: STOCK_MCP_TOKEN not set}

If STOCK_MCP_TOKEN is not set:

1. Visit the management platform (nps_enhanced web panel)
2. Navigate to "MCP Data Query" subscription page
3. Purchase a query quota pack (e.g., 10k records for 10 CNY)
4. Copy the issued token
5. Set the environment variable:

   export STOCK_MCP_TOKEN="eyJ..."
   export STOCK_MCP_SERVER_URL="https://your-node:8001/messages"
   

MCP Server Configuration

Add to your MCP client configuration:

{
  "mcpServers": {
    "stock-data": {
      "type": "streamable-http",
      "url": "${STOCK_MCP_SERVER_URL}",
      "headers": {
        "Authorization": "Bearer ${STOCK_MCP_TOKEN}"
      }
    }
  }
}

Available Data Categories

Usage Notes

• Each tool call returns data and counts against your query quota
• The response includes _usage.record_count showing records returned
• The response includes _usage.quota_remaining showing remaining quota
• When quota is exhausted, purchase additional packs from the management platform
• Data is sourced from ClickHouse and covers the full available history

Billing

• Billed per record (data row) returned by each tool call
• Query packs are valid for 90 days from purchase
• Multiple packs stack additively (quota accumulates)
• Usage is reconciled asynchronously between the MCP server and management platform

Troubleshooting

• 401 "API key required": STOCK_MCP_TOKEN is not set or not passed in Authorization header
• 401 "Token expired": Your token has expired. Purchase a new quota pack to get a fresh token
• 401 "Invalid token": Token is malformed or the server's public key doesn't match
• No data returned: Check that the requested date is a trading day, or the stock code is valid
• Quota exhausted: The _usage.quota_remaining will show 0. Purchase additional packs
