Kakao Navigation

Use navigation features such as route guidance, pathfinding, and waypoint setting through the Kakao Navigation API.

Key Features

• Route guidance from origin to destination
• Route planning with waypoints
• Multi-origin route calculation
• Multi-destination route calculation
• Future time-based route calculation

Basic Information

Authentication Method

Authenticate using API Key.

Input Parameters

• API Key (required): REST API key issued from Kakao Developers Center

Supported MCP Tools

Route Guidance Tools

navigation_directions

Calculate routes from origin to destination.

Input Parameters:

• origin (required): Origin coordinates (longitude,latitude)
• destination (required): Destination coordinates (longitude,latitude)
• priority (optional): Route priority (RECOMMEND, TIME, DISTANCE)
• car_fuel (optional): Vehicle fuel type
• car_hipass (optional): Whether to use Hi-pass
• alternatives (optional): Whether to provide alternative routes
• road_details (optional): Whether to provide detailed road information

navigation_waypoints

Calculate routes including waypoints.

Input Parameters:

• origin (required): Origin coordinates
• destination (required): Destination coordinates
• waypoints (required): List of waypoint coordinates
• priority (optional): Route priority
• car_fuel (optional): Vehicle fuel type
• car_hipass (optional): Whether to use Hi-pass

navigation_origins

Calculate routes from multiple origins to one destination.

Input Parameters:

• origins (required): List of origin coordinates
• destination (required): Destination coordinates
• priority (optional): Route priority
• car_fuel (optional): Vehicle fuel type
• car_hipass (optional): Whether to use Hi-pass

navigation_destinations

Calculate routes from one origin to multiple destinations.

Input Parameters:

• origin (required): Origin coordinates
• destinations (required): List of destination coordinates
• priority (optional): Route priority
• car_fuel (optional): Vehicle fuel type
• car_hipass (optional): Whether to use Hi-pass

navigation_future

Calculate routes based on future time.

Input Parameters:

• origin (required): Origin coordinates
• destination (required): Destination coordinates
• departure_time (required): Departure time
• priority (optional): Route priority
• car_fuel (optional): Vehicle fuel type
• car_hipass (optional): Whether to use Hi-pass

Usage Example

The Kakao Navigation MCP server should be used together with the Kakao Map MCP server.
To find routes from origin to destination, first convert place queries to coordinates and use them to calculate routes.

For example,

• When you input the prompt “Tell me the route from Gangnam Station to Hongik University Station”,
• The LLM first calls the map_address_to_coord tool from the Kakao Map MCP server to get coordinates for Gangnam Station and Hongik University Station.
• Then the LLM calls the navigation_directions tool from the Kakao Navigation MCP server to calculate the route.
• Finally, it responds in the chat based on the tool call results.

API Key Setup Method

1. Register an application in Kakao Developers Center.
2. Get a REST API key.
3. Select Kakao Navigation integration in QueryPie AI.
4. Complete the connection by entering the issued API key.

Precautions

• Keep your generated API Key secure.
• Check daily call limits and use appropriately.
• Coordinates use the WGS84 coordinate system.
• Provides routes that reflect real-time traffic information.
