    About this skill

    The problem

    Manual financial vetting and asset data retrieval projects are prone to human error and data aging. Developers often struggle to integrate reliable tax validation and market pricing without managing complex API states and error handling.

    What it does

    • Interfaces with the financial_market_data MCP tool for real-time asset pricing.
    • Validates tax details, VAT numbers, and IBANs for client vetting.
    • Manages session state and caching to optimize API usage and cost.
    • Handles upstream service errors and rate limits gracefully without crashing.
    • Enforces data integrity by preventing hallucinated or invented financial results.

    Frameworks & tools

    Alpha Vantage API, MCP (Model Context Protocol), .env configuration.

    Why this beats prompting it yourself

    Standard prompts often result in hallucinated stock prices or outdated tax formats. This skill provides a rigid execution layer with persistent session memory and standardized error codes, ensuring the AI acts as a reliable interface to live financial data rather than a generator of guesses.

    Use cases

    • Verify client IBANs and VAT numbers before generating invoices.
    • Retrieve live stock symbols and market data for financial reports.
    • Sanitize and validate tax details during onboarding workflows.
    • Audit financial state using session-aware cache management.

    Known limitations

    Requires an Alpha Vantage API key. Does not support bulk processing in a single call; one call per asset or validation check is required.
