Scored across 2 tools
The two tools are distinct: one filters by specific line, the other returns all lines for Suwon station. However, they are closely related and could cause confusion if an agent intends to get arrivals for a line not at Suwon station.
Both use 'get_' prefix and a noun phrase. However, one uses 'line_arrivals' and the other 'subway_arrivals', which are not perfectly parallel (line vs subway). Minor inconsistency.
Two tools is minimal but could be appropriate for a server focused solely on arrivals at a single station. However, the scope feels too narrow for a subway MCP, which typically covers multiple stations and features.
The server only provides arrivals for Suwon station on two lines. It lacks essential functionality like schedules, delays, station lookup, or other stations, making it severely incomplete for a subway information server.
