## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1110 tokens (~277/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the SL – Stockholm public transport MCP server?

SL – Stockholm public transport is a hosted endpoint at https://sl-mcp.miltonlindblad.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (4)

### `find_stop` (~181 tokens)

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' gives the train station and bus stops): pick by name and modes, or ask the user. Typos are fine, abbreviations are not: write 'Tekniska högskolan', not 'KTH'. Returns one line per stop: '<id>: <town>, <name> (<modes>)'.

Input parameters:

- `limit` (integer): Maximum number of stops to return
- `query` (string, required): Stop or station name, e.g. 'Slussen' or 'Arlanda'. Typos are fine, abbreviations are not.

### `get_departures` (~266 tokens)

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 announced track work or broken lifts, use get_disruptions. Real-time data from SL: at most 3 departures per line and direction, up to 3 hours ahead. `towards` matches the final destination only: for a station on the way (e.g. 'mot T-Centralen' from Slussen), leave it out and pick the direction from the results. An unknown siteId gives no departures, not an error.

Input parameters:

- `limit` (integer): Maximum number of departures
- `line` (string): Only this line number, e.g. '14' or '43X'
- `minutes` (integer): How many minutes ahead to look, at most 180
- `siteId` (integer, required): Stop id from find_stop
- `towards` (string): Only departures whose final destination contains this, e.g. 'Ropsten'
- `transportMode` (string): Only this mode

### `get_disruptions` (~156 tokens)

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 get_departures instead. The text is in Swedish, so translate it if needed, and is cut at 800 characters. Results are cached for 1 minute, as SL asks. Leave both filters out to list everything.

Input parameters:

- `lines` (array): Only these line numbers, e.g. ['13', '14'], or metro colours, e.g. ['grön linje']
- `transportMode` (string): Only this mode

### `plan_trip` (~315 tokens)

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 minutes and the station exit (uppgång). Use it for 'how do I get to X' and 'when must I leave'; for departures from one stop, use get_departures. Addresses are fuzzy matched, so the result starts with what each one matched. Times are Stockholm time. Unknown stops, the same stop twice and times outside the timetable give a clear error. SL cannot plan step-free trips: for a wheelchair or pram, use prefer 'least walking' and check get_disruptions for broken lifts at the stops.

Input parameters:

- `arriveBy` (boolean): true: arrive by `time`. false: leave at `time`.
- `from` (required): Start: a stop id from find_stop, or a street address like 'Götgatan 76, Stockholm'
- `modes` (array): Only these modes, e.g. ['boat'] for 'by boat'. Leave out for all.
- `prefer` (string): What to optimise for: fastest (default), fewest changes or least walking
- `time` (string): Stockholm time as YYYY-MM-DDTHH:MM. Leave out to leave now.
- `to` (required): Destination: a stop id from find_stop, or a street address
