NLQueries MCP server

NLQueries is a helper that turns plain English questions into real database queries. You type something like "how many orders shipped last month?" and it writes the SQL, checks it, and runs it for you. It is handy if you work with data but do not write SQL yourself, or if you just want to save time.

What this MCP server does

You ask your AI a question in everyday words. The AI passes it to NLQueries. NLQueries looks at your database structure and your past queries, writes SQL, checks that the SQL is valid, and runs it against your database. Then it sends the result back to your AI, which explains it to you in the chat.

• Ask follow-up questions that keep the earlier context
• Ask questions about documents like PDFs or Word files
• Get a mix of database and document answers in one reply
• Rate answers so the tool learns what good looks like

Try asking your AI

• “How many orders shipped last month?”
• “And how many of those were returned?”
• “What tables do we have about customers?”
• “What does our refund policy document say about late returns?”

What it gives back to you

You get a written answer in the chat, usually with the number or list you asked for. You also get the SQL that was used, so you can see how the answer was worked out. If the answer came from a document, you get the source it came from. Sometimes it shows a cached answer if you asked something very similar before.
