Privacy & Data Policy

What data does this MCP server collect?

• API Key: Your API key is sent to the Capital Advantage backend over HTTPS with every request. The backend stores a SHA-256 hash of the key for authentication — the raw key is never stored.
• Request logs: The backend logs API call counts and timestamps for rate limiting. IP addresses may be logged for abuse prevention.
• No personal data: The MCP server itself is stateless — it does not store any user data, conversation history, or query results locally.
• No data selling: Capital Advantage does not sell, share, or monetize user data or API usage patterns with any third parties.
• HTTPS only: All communication between the MCP server and backend uses TLS encryption.

For questions about data handling, contact: [e-mail]

Troubleshooting

"CA_API_KEY environment variable is required"

You need to set your API key in the Claude Desktop config. Get one at beta.capitaladvantage.finance/settings/developer.

"401 Unauthorized" or "Invalid API key"

Your API key may be invalid or expired. Generate a new one from the developer settings page.

"429 Too Many Requests"

You've exceeded your rate limit (100 calls/day on free tier). Wait for the daily reset or upgrade to Pro.

"Connection timeout" or "Network error"

The Capital Advantage backend may be temporarily unavailable. Try again in a few minutes.

Tool returns empty or unexpected data

Some tools require market hours for live data (Indian markets: 9:15 AM - 3:30 PM IST, Monday-Friday). Historical data and analysis tools work anytime.
