FAQ

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.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
