🚗 Swiss Road & Mobility MCP Server

MCP Server for Swiss road mobility — shared vehicles, EV charging, traffic alerts, Park & Rail, and multimodal trip planning

🇩🇪 Deutsche Version

Overview

swiss-road-mobility-mcp provides AI-native access to Swiss road and mobility data sources:

Source	Data	API	Auth
sharedmobility.ch	Bikes, e-scooters, cars (GBFS)	REST/JSON	None
ich-tanke-strom.ch	EV charging stations	GeoJSON	None
opentransportdata.swiss	Traffic events, counting stations	DATEX II / SOAP+XML	Free key
data.sbb.ch	Park & Rail facilities	REST/JSON (Opendatasoft)	None
transport.opendata.ch	Public transport connections	REST/JSON	None
geo.admin.ch	Address geocoding, road classification	REST/JSON	None

If the Swiss Transport MCP is the GA pass for rail, this server is the vignette + Park & Rail card + sharing subscription for the road — together they paint the complete multimodal picture of Swiss mobility.

Anchor demo query: "I'm in Dietikon with my car. I need to get to Bern. Where can I park? Which train should I take?"

---

Features

• 15 tools across six data sources (Phase 1–4)
• road_mobility_snapshot — aggregated mobility overview for any location
• road_multimodal_plan — car + Park & Rail + public transport in one plan
• No API key required for 12 of 15 tools
• Dual transport — stdio (Claude Desktop) + SSE (cloud)
• Rate limiting + caching for all endpoints

---

Prerequisites

• Python 3.11+
• uv (recommended) or pip

---

Installation

# Clone the repository
git clone https://github.com/malkreide/swiss-road-mobility-mcp.git
cd swiss-road-mobility-mcp

# Install
pip install -e .
# or with uv:
uv pip install -e .

Or with uvx (no permanent installation):

uvx swiss-road-mobility-mcp

---

Quickstart

# stdio (for Claude Desktop)
swiss-road-mobility-mcp
# or:
python -m swiss_road_mobility_mcp.server

# SSE (for cloud / Render.com)
MCP_TRANSPORT=sse MCP_PORT=8001 swiss-road-mobility-mcp

Try it immediately in Claude Desktop:

"Show me everything mobility-related at Zurich HB." "Find shared bikes near Bern Bahnhof." "Where can I charge my EV near Lucerne?"

→ More use cases by audience →

Configuration

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "swiss-road-mobility": {
      "command": "uvx",
      "args": ["swiss-road-mobility-mcp"],
      "env": {
        "OPENTRANSPORTDATA_API_KEY": "<your-token>"
      }
    }
  }
}

Or with python:

{
  "mcpServers": {
    "swiss-road-mobility": {
      "command": "python",
      "args": ["-m", "swiss_road_mobility_mcp.server"],
      "env": {
        "OPENTRANSPORTDATA_API_KEY": "<your-token>"
      }
    }
  }
}

Shared mobility, EV charging, Park & Rail, and the multimodal planner work without an OPENTRANSPORTDATA_API_KEY. The key is only required for the DATEX II traffic tools.

Config file locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Cloud Deployment (SSE for browser access)

For use via claude.ai in the browser (e.g. on managed workstations without local software):

Render.com (recommended):

1. Push/fork the repository to GitHub
2. On render.com: New Web Service -> connect GitHub repo
3. Set start command: MCP_TRANSPORT=sse MCP_PORT=8001 swiss-road-mobility-mcp
4. In claude.ai under Settings -> MCP Servers, add: https://your-app.onrender.com/sse

SSE security (SEC-009)

A public SSE endpoint is reachable by anyone. To protect it (and your upstream API quota), configure these environment variables on the host:

Variable	Effect
MCP_AUTH_TOKEN	When set, every SSE request must send Authorization: Bearer <token>. Unset = unauthenticated (the server logs a loud warning at startup). Strongly recommended for any public deployment.
MCP_RATE_LIMIT	Max requests per client IP per window (default 60, 0 disables).
MCP_RATE_WINDOW	Window length in seconds (default 60).
ALLOWED_ORIGINS	Comma-separated CORS origins for browser clients (default *).

The local stdio transport needs none of this — it runs in the user's trusted context.

Observability (OBS-003 / OBS-006)

Variable	Effect
MCP_LOG_LEVEL	Log level: DEBUG / INFO (default) / WARNING / ERROR.
MCP_LOG_FORMAT	text (default) or json for structured logs. All logs go to stderr.
MCP_TRACING_ENABLED	true enables OpenTelemetry tracing (off by default).
OTEL_EXPORTER_OTLP_ENDPOINT	OTLP collector URL; setting it also enables tracing. Standard OTEL_* vars are honoured by the SDK.

Tracing needs the optional extra: pip install 'swiss-road-mobility-mcp[tracing]'. Once enabled, every upstream API call is traced automatically (httpx instrumentation) and SSE requests get server spans with W3C trace-context propagation.

Example Use Cases

Query	Tool
"Find shared bikes near Zurich HB"	road_find_sharing
"Where can I charge my EV near Bern?"	road_find_charger
"Any traffic incidents on the A1?"	road_traffic_situations
"Where can I park near Winterthur station?"	road_park_rail
"Plan my trip from Dietikon to Bern by car + train"	road_multimodal_plan

---

API Key for Traffic Tools

1. Register: https://api-manager.opentransportdata.swiss
2. Create a new application -> subscribe to the "Strassenverkehr" API
3. Copy the token

export OPENTRANSPORTDATA_API_KEY=<your-token>

Without a key, the traffic tools return a descriptive error message including the exact registration link — no crash.

Known Limitations

• Shared Mobility: The sharedmobility.ch API does not enforce strict radius filtering; vehicles slightly outside the specified radius may appear
• EV Charging: Station naming conventions vary between operators; some stations may appear without detailed names
• Traffic (DATEX II): Requires a free API key; without it, traffic tools return helpful error messages
• Park & Rail: SBB occasionally renames endpoints; the server includes a fallback chain
• Multimodal Planner: Response time depends on the slowest of the queried sources

---

Testing

# All tests
pytest tests/ -v

# Quick check (without pytest)
python tests/test_phase3.py

---

Safety & Limits

• Read-only: All tools perform HTTP GET requests only — no data is written, modified, or deleted on any upstream system.
• No personal data: Location coordinates passed as tool inputs are not stored, logged, or forwarded beyond the immediate API request. API responses contain no PII — only vehicle counts, charger availability, traffic events, and geographic metadata.
• Rate limiting: The server enforces client-side rate limits (Shared Mobility: 30 req/60s; EV Charging: 10 req/60s) to protect upstream APIs. The DATEX II key is subject to opentransportdata.swiss fair-use terms.
• Caching: Responses are cached in-process (Sharing: 60s · EV: 5 min · Park+Rail: 5 min · Traffic: 1–2 min). Real-time data reflects the cache age, not necessarily the current second.
• Terms of service: Data is subject to the ToS of each upstream source — sharedmobility.ch, ich-tanke-strom.ch, opentransportdata.swiss, data.sbb.ch (CC BY), geo.admin.ch (BGDI).
• No guarantees: This server is an independent community project, not affiliated with SBB, ASTRA, sharedmobility.ch, or any API provider. Availability depends on upstream services.
