URDB MCP server

This is a small helper that connects your AI assistant to URDB, a site with engineering calculators and a product integrity database. Once it is set up, you can ask your AI things like what resistor a blue LED needs, or whether a product has quietly gotten worse over the years. It is handy for anyone who works with electronics, hardware or firmware, and for people who want to check how a product has changed before buying.

What this MCP server does

You ask your AI a question in plain language, like what trace width you need for a certain current. The AI sends that question to this helper, which passes it to the URDB service. URDB runs the calculation or looks up the product, and sends the result back. Your AI then shows you the answer, the numbers behind it, and often a link to the same tool on the URDB website.

What you can do with it

• Run electronics and firmware calculators, like LED resistors, baud rates and trace widths
• Search URDB for products and see their integrity scores
• Look up the full integrity breakdown of a specific product
• See documented downgrade events for a product over time
• List and filter products by category, brand or score
• Get the worked steps behind a calculation, not just the final number

Try asking your AI

• “Size the current-limiting resistor for a blue LED on 5 V”
• “What UBRR do I need for 9600 baud on a 16 MHz AVR?”
• “Which laptops have the highest integrity scores?”
• “Has the KitchenAid Stand Mixer gotten worse over the years?”

What it gives back to you

You get answers in the chat, usually with the final value and the numbers behind it. For calculators you also get the worked steps and a link to the same tool on the URDB website. For products you get scores, a breakdown across several dimensions, or a list of changes over time. It is all shown as text you can read and copy.
