Washington's mountain passes, checked every few minutes, and stories about places along the road.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What it can do

Common questions

Is WithBy safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

WithBy

Washington's mountain-pass conditions, checked every few minutes, and hundreds of short stories about the places along the road, told by Sal, WithBy's narrator.

This repository connects AI agents to WithBy through WithBy's own remote MCP server, https://withby.ai/mcp. It is a plugin for Cursor and Claude Code and an extension for Gemini CLI. Nothing installs or runs on your computer: the tools come from the server.

What it does

WithBy checks Washington's mountain passes every few minutes and judges each direction of Snoqualmie, Stevens, White and Blewett passes: open, chains or closed, with the time it looked. For 12 other passes and the I-90 and SR 520 floating bridges it gives WSDOT's own words.

It has hundreds of short stories about the places along the state's highways, told by Sal, WithBy's road-trip narrator. Ask whether a pass is open, ask for a story about a place, hear what Sal knows near a town or along a stretch of highway, and save the stories you want him to tell you on your next drive. WithBy covers Washington's highways today and says so when you ask about somewhere else.

The server

WithBy's MCP server is hosted at https://withby.ai/mcp (streamable HTTP; registry name ai.withby/withby). The server's code is not public. This repository holds the client plugin configuration for Cursor, Claude Code and Gemini CLI, and it is the place to report issues or ask questions about the WithBy connector. You can also write to support@withby.ai.

Signing in

The tools marked "yes" need a WithBy account. The first time you use one, your agent opens WithBy's sign-in page, and you choose whether to let it use your account. The other tools work without signing in. You can disconnect at any time from your WithBy profile.
