mcp-server-usace-iwr

一个MCP（模型上下文协议）服务器，封装了美国陆军工程兵团（USACE）水资源研究所（IWR）的河流里程标志ArcGIS要素服务，让LLM能够定位美国通航河流上的河流里程标志，并回答"我在哪个河流里程位置？"这类问题。

  • 数据集： USACE河流里程标志

  • 服务： https://services7.arcgis.com/n1YM8pTrFmm7L4hs/arcgis/rest/services/usace_river_mile_markers/FeatureServer/0

  • 认证： 无（公共服务）

  • 坐标系： WGS84（EPSG:4326）十进制度数

工具

用途

usace_rivermile_nearest

返回距离给定经纬度最近的一个标志（含距离和方位角）。

usace_rivermile_find_markers

查找某点附近（半径内）或GeoJSON几何/边界框内的标志。

usace_rivermile_query

按河流名称和/或里程值范围筛选标志，支持分页。

所有工具均为只读，并返回溯源信息（来源机构、数据集、服务URL、图层、坐标系、检索时间）。

图层字段

name、LONGITUDE1、LATITUDE1、MILE、RIVER_CODE、RIVER_NAME、 RIVER_NUMB、SOURCE。

本地运行（stdio）

uv sync
uv run python -m usace_iwr_server.app

服务器默认使用stdio传输方式。如果设置了PORT（或DATABRICKS_APP_PORT）环境变量，则改为在/mcp提供可流式HTTP服务，并附带/health就绪检查端点。

容器化/部署

bash scripts/build-and-push.sh   # builds linux/amd64 and pushes to GHCR

开发
