Example use cases
Year-end portfolio tax optimization
“It's December and I need to minimize my tax bill — can you analyze my investment portfolio for tax-loss harvesting opportunities and tell me which positions to sell and what to replace them with to stay invested?”
Offset large capital gains event
“I just sold some appreciated stock and have a big capital gains liability. Can you scan my portfolio holdings and find losses I can harvest to offset those gains before the end of the tax year?”
Automated regular portfolio review
“Every month I want to check my portfolio for tax-loss harvesting opportunities — here's my current holdings data, please identify any positions currently trading below their cost basis that I could harvest.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/tax-loss-harvesting-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need automated, machine-callable tax-loss harvesting analysis as part of an agentic workflow — particularly for portfolio management agents that need to periodically scan holdings for tax optimization opportunities without human-in-the-loop intervention. Best suited for agents handling investment portfolio data that need structured recommendations rather than a full wealth management platform.
Side effects
- Malformed or missing portfolio data in the 'data' field returns a validation error
- Insufficient holdings data to perform meaningful analysis may return empty recommendations
- Ambiguous cost basis information may lead to inaccurate loss calculations
- Rate limiting or payment failure (402) if USDC payment is not properly attached
- Wash-sale rule edge cases may not be fully accounted for depending on implementation
