DeepSeek TUI MCP troubleshooting gets easier once you stop treating every failure like an MCP problem

Many MCP issues are really provider, config, or path issues wearing an MCP label. You save time by isolating basic setup first and only then moving into server-level troubleshooting.

Why MCP failures are easy to misread

MCP sits on top of a working base install and config path, so a weak foundation can easily look like an MCP-specific failure.

What to isolate first

Does the base DeepSeek TUI install work without MCP?
Are provider auth and config already stable?
Is the MCP server actually reachable and described the way you expect?
