Summary

Add a list_snapshot_options_chain tool that retrieves options chain data including greeks from the Massive API.

Motivation

Options traders need access to comprehensive options chain data with greeks (delta, gamma, theta, vega) for analysis and strategy development. Currently there's no way to fetch this data through the MCP server.

Proposed Implementation

Add a new tool list_snapshot_options_chain with parameters:

• underlying_symbol (required): The underlying stock symbol
• expiration_date (optional): Filter by specific expiration date
• strike_price (optional): Filter by specific strike price
• option_type (optional): Filter by 'call' or 'put'

The tool should return options chain data including:

• Contract details (symbol, strike, expiration, type)
• Pricing data (bid, ask, last, volume, open interest)
• Greeks (delta, gamma, theta, vega, rho)

Additional Context

This would enable covered call analysis, options portfolio management, and other options strategies that require greeks data.
