About Searoute
Searoute is a Python MCP server for maritime routing, intended for maritime operations and research. It returns oceangoing distances and route geometry, and can compare routes with great-circle distances.
Key features
- 01Calculate oceangoing route distances
- 02Return routes with GeoJSON geometry
- 03Calculate great-circle distances
- 04Accept latitude and longitude coordinates
Use cases
- 01Estimate sea distance between two ports or locations
- 02Retrieve route geometry for mapping
- 03Compare sea routes with great-circle distances
MCP support
Exposes `compute_distance`, `compute_route`, and `compute_geodesic` tools to MCP clients for maritime and geodesic distance calculations.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Overview
searoute_mcp is a Model Context Protocol (MCP) server for maritime routing.
It integrates searoute-py with MCP, exposing tools that allow LLM clients (e.g. Claude Desktop) to:
- Compute oceangoing route distances (in nautical miles)
- Retrieve full oceangoing routes with waypoints (GeoJSON format)
- Compare against geodesic great-circle distances
All tools accept latitude, longitude as inputs for user friendliness, while internally converting to the required searoute format.
Installation
Clone the repository and install dependencies:
git clone https://github.com/ShippingIntel/searoute_mcp.git
cd searoute_mcp
python3 -m venv .venv
source .venv/bin/activate # Linux/macOS
.venv\Scripts\activate # Windows
pip install -r requirements.txt
Dependencies:
mcp[python]>=0.1.0searoute>=1.4.3geopy>=2.4.1
Quickstart
Run the server locally:
python -m mcp_server.main
Install into Claude Desktop:
mcp install mcp_server/main.py
Test with the MCP Inspector:
mcp dev mcp_server/main.py
Core Tools
-
compute_distanceShortest oceangoing route distance (nm) between two coordinates. -
compute_routeFull oceangoing route (GeoJSON geometry + distance). -
compute_geodesicGreat-circle (sphere) distance in nautical miles, ignoring land/sea constraints.
Example Prompts
All prompts use latitude, longitude ordering.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
