A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
An MCP server for Estonian public transport — timetables, trip planning, stop search, and real-time vehicle tracking.
| Tool | Description |
|---|---|
search_stops | Search for stops by name (e.g. "Viru", "Balti jaam") |
get_departures | Get upcoming departures from a stop, with real-time predictions |
plan_trip | Plan a trip between two coordinates with date/time options |
nearby_stops | Find stops within a radius of a location |
get_route | Get route details including all stop patterns |
get_trip_stops | Get full schedule of a specific trip — all stops with arrival/departure times |
tallinn_vehicles | Real-time GPS positions of Tallinn buses, trams, and trolleybuses |
This server runs via uvx, a zero-install Python package runner. Install uv first:
# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh
# Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
# or via Homebrew
brew install uvNo other setup needed — uvx automatically downloads dependencies on first run.
Add to your MCP settings (.claude/settings.json or project-level .mcp.json):
{
"mcpServers": {
"estonian-transport": {
"command": "uvx",
"args": ["estonian-transport-mcp"]
}
}
}Config file location:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.jsonAdd to the mcpServers section:
{
"mcpServers": {
"estonian-transport": {
"command": "uvx",
"args": ["estonian-transport-mcp"]
}
}
}Note: Claude Desktop may not finduvxin its PATH. If the server fails to start, replace"uvx"with the full path. Find it by runningwhich uvxin your terminal, then use that path:
>
``json { "mcpServers": { "estonian-transport": { "command": "/Users/yourname/.local/bin/uvx", "args": ["estonian-transport-mcp"] } } } ``Restart Claude Desktop after saving the config.
Run as an HTTP server for remote access (e.g. from claude.ai/code on mobile):
estonian-transport-mcp --transport streamable-http --port 8000Then connect to it from any MCP client using the URL http://your-server:8000/mcp.
