deadends.dev MCP server

This is a helper that tells your AI which fixes and which advice are known to fail. It covers two things: common code errors (like Python or Docker errors) and country-specific rules (like visa, banking, and local customs). It is handy if you work with code, travel, or deal with rules in other countries.

What this MCP server does

You ask your AI about an error or a country rule. Your AI sends that question to this helper. The helper looks it up in a library of over two thousand known cases, each with a list of fixes that fail and fixes that work, plus success rates. Your AI then tells you what not to try and what to try instead. For country topics, it also knows the right answer for that specific country.

What you can do with it

• Look up a code error and see which fixes usually fail
• Get working workarounds with success rates for that error
• Check country-specific rules like visa or banking requirements
• Search across all covered topics by keyword
• See all dead ends for one country in a single list
• Report back whether a suggested fix actually worked
• Follow a chain of related errors that often happen together

Try asking your AI

• “I got ModuleNotFoundError: No module named torch, what should I try?”
• “My Docker container says no space left on device, what are the known dead ends?”
• “I am traveling to Japan, what are common mistakes about tipping and chopsticks?”
• “What visa rules should I know before visiting South Korea as a tourist?”

What it gives back to you

You get back a short, clear answer in the chat. It lists the dead ends to avoid, each with a rough failure rate, and the workarounds to try, each with a rough success rate. For country questions, it gives the rule that applies in that country. You can also ask for a list of all entries for one country or one topic.

Who it's for

Developers stuck on errors, and anyone who travels or works across countries and wants advice that fits the local rules.
