What's Wrong?

An unreachable plugin/MCP server causes all tool calls to hang and get interrupted, not just the plugin-related ones
Basic operations like file reads and grep searches are affected
Workaround: manually disabling the plugin in settings.json and removing entry of mcpServer from claude.json

What Should Happen?

A plugin or MCP server that's unreachable should fail gracefully with a timeout and warning, not hang the entire session and block all tool calls including basic things like file reads and searches.
