What is Luca Assistant?
Luca Assistant is a comprehensive technical solution for managing US credit card rewards and portfolio health. Operating as a sophisticated utility within the Openclaw Skills ecosystem, it allows users to query detailed information on over 150 credit cards, including category multipliers, annual credits, and current welcome offers. It is specifically designed to handle complex issuer logic like the Chase 5/24 rule and Amex lifetime language, ensuring users make informed application decisions.
By leveraging a local SQLite database, Luca Assistant provides high-performance access to card metadata sourced from reliable industry providers. The skill functions as an MCP (Model Context Protocol) server, enabling seamless integration with AI coding agents to automate the research, comparison, and tracking of financial products without manual data entry or fabrication.
Luca Assistant Use Cases
- Comparing annual fees and earning multipliers between multiple premium travel cards.
- Identifying the highest current sign-up bonuses worth a specific dollar amount.
- Tracking personal credit card portfolios to calculate remaining Chase 5/24 slots.
- Verifying bank-specific application rules before submitting a new card request.
- Enriching local card data with updated earning rates found through web research.
How Luca Assistant Works
- The Openclaw Skills environment initializes the Luca Assistant MCP server and verifies the local environment.
- A local database is seeded with data for 150+ cards, including current offers and APRs from external sources.
- The agent invokes specific luca_ tools to query card details, compare benefits, or check portfolio status.
- If data gaps are identified, the agent uses enrichment workflows to update the local database via web search results.
- Portfolio changes (adding or closing cards) are persisted to the database to maintain an accurate 5/24 count and historical record.
Luca Assistant Setup
Ensure you have python3 and uv installed. To set up Luca Assistant within Openclaw Skills, run the following commands:
# Ensure local bin is in your path
