Frequently asked questions
How can I see all the laws and decrees published in the BOE on a specific date?
Use the get_boe_summary tool by providing the date in YYYYMMDD format. The agent will return the full index of documents and sections published on that day.
Can I search for the most recent version of a specific law like the Civil Code?
Yes! You can use search_consolidated_legislation with a query like 'Código Civil' to find the latest updated version, or use get_legislation_text if you already have the ID (e.g., BOE-A-1889-4763).
Is it possible to retrieve only a specific article of a law instead of the whole text?
Absolutely. First, use get_legislation_text_index to find the block ID for the article you need, then use get_legislation_block to fetch only that specific content.

Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
