What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

find_stop
Find Stockholm public transport (SL) stops by name and return their ids, names and transport modes. Use it to get the siteId for get_departures, or a stop id for plan_trip. Not for street addresses: pass those to plan_trip as text instead. A name can match several stops ('Arlanda
get_departures
List live departures from one SL stop, soonest first: line, mode, final destination, direction (1 or 2), platform or bus stop letter, minutes or clock time, delay, cancellation and SL's notes. Use it for 'when does the next X leave from Y'. To get from A to B, use plan_trip; for
get_disruptions
List disruptions SL has announced: track work, closed entrances, broken lifts and replacement buses, with the lines affected and until when. Use it to check a line or the stops of a trip before travelling, e.g. lifts for a wheelchair. For live delays and cancelled departures, use
plan_trip
Plan trips by SL public transport between two stops or street addresses, leaving or arriving at a given time. Returns up to 3 trips, plus walking all the way when that takes at most 30 min. Each ride lists line, direction, platform, stops, crowding and delay; each walk lists minu

Common questions

Is SL – Stockholm public transport 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 (0.2.0) reached the registry 4 days ago.

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?

README from the maker

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

sl-mcp

An MCP server for Stockholm public transport (SL). Connect it to Claude or another MCP client and ask about departures, disruptions and trips in plain Swedish or English.

När går nästa tunnelbana från Slussen mot Ropsten?

Är det några störningar på röda linjen? How do I get from Odenplan to Arlanda? Hur tar jag mig från Sundbyberg till Götgatan 76?

It uses SL's open APIs, which don't need an API key.

An answer looks like this:

Gå 08:31 från Sundbybergs centrum, så är du framme på Götgatan 76 kl 08:58.

1. 08:31 Tunnelbana 10 mot Kungsträdgården från spår 2. Åk 7 stationer till T-Centralen.

2. 08:47 Byt till tunnelbana 17 mot Skarpnäck från spår 4. Åk 3 stationer till Medborgarplatsen.

3. 08:52–08:58 Gå ut via uppgång Folkungagatan Götgatan och gå 6 min till Götgatan 76.

Use it without installing

A hosted server runs on Cloudflare Workers. No API key or login is needed:

https://sl-mcp.miltonlindblad.workers.dev/mcp

Add it as a custom connector in claude.ai or ChatGPT, or in any MCP client that supports Streamable HTTP. In Claude Code:

claude mcp add --transport http sl https://sl-mcp.miltonlindblad.workers.dev/mcp

Tools

find_stop: search for a stop by name, typos are fine, and get its id
get_departures: live departures from a stop with platform or bus stop letter, delays and cancellations. Filter by mode, line or destination
get_disruptions: announced disruptions such as track work, broken lifts and replacement buses, by line, mode or metro colour ("grön linje")
plan_trip: up to 3 trips between stops or street addresses, leaving or arriving at a given time. Each ride shows platform, stops, crowding and delay, and each walk shows minutes and which station exit to use. You can ask for only some modes (e.g. boat) and for fewest changes or least walking

Prompts

Ready-made questions to pick in your client, e.g. as slash commands:

trip: how to get from one place to another, optionally arriving by a given time
departures: the next departures from a stop

Install

Requires Node.js 20 or later.

git clone https://github.com/Hashtagsmile/sl-mcp.git

cd sl-mcp npm install npm run build

Claude Code

claude mcp add sl -- node /path/to/sl-mcp/dist/index.js

Claude Desktop

Add this to claude_desktop_config.json and restart Claude Desktop:

"mcpServers": { "sl": { "command": "node", "args": ["/path/to/sl-mcp/dist/index.js"] } } }

Development

npm run dev       # compile on save

npm test # run the tests npm run inspect # try the tools in the MCP Inspector

The tests use recorded API responses in test/fixtures/, so they don't call SL.

Deploy to Cloudflare Workers

src/worker.ts serves the same tools over HTTP at /mcp.

npx wrangler dev      # run it locally on http://localhost:8787/mcp

npx wrangler deploy # deploy to your Cloudflare account

Limitations

SL returns at most 3 departures per line and direction.
Disruption messages are in Swedish only.
There is no "nearest stop" search, since SL has no keyless API for it.
SL can't plan step-free trips. For a wheelchair, the tools suggest least walking and checking for broken lifts.
Addresses work, business names don't: "Götgatan 76" works, "Sellpy" doesn't.
Departures reach at most 3 hours ahead. For later, use plan_trip with a time.
