What is GeoSource MCP?

GeoSource MCP is a standardized data access server implementing the Model Context Protocol (MCP). It connects AI environments (such as Claude Desktop, Cursor, and other MCP clients) directly with a verified database of 2,198+ global GIS spatial services and 1,561+ spatial layers.

Registry Status: Officially audited, approved, and listed on the Glama MCP Registry.

Why is this needed?

When developing GIS applications or writing spatial scripts, AI assistants typically do not have direct access to up-to-date, public GIS service endpoints. This often leads to incomplete answers, outdated references, or hallucinated URLs.

GeoSource MCP connects directly to an indexed SQLite database (gis_services.db), providing AI models with low-latency (sub-0.05s) tools to discover real public endpoints (including OGC WMS, WFS, WMTS, XYZ Tiles, ArcGIS REST, and STAC).

Key Highlights

  • Sub-0.05s Response Time: Local SQLite index provides millisecond-level search without network roundtrips.

  • 99% Token Reduction: Fetches only matching records (200 ~ 500 tokens per search) instead of injecting megabytes of raw spreadsheets into the prompt.

  • Hallucination-Free: Ensures endpoints, layer names, and authentication requirements passed to the code are 100% verified.

  • Two-Way Maintenance: Supports syncing from Excel files, and allows AI models to update broken URLs dynamically via built-in tools.

Database Contents

  • 2,198+ Master Services: Covers national and regional mapping agencies, open data portals, elevation/DEM providers, satellite imagery, and environmental datasets.

  • 1,561+ Layer Details: Specific sub-layer identifiers for direct map integration.

  • 50+ Attributes per Service: Protocol, country, category, authentication type, API key requirements, format, and commercial terms.

🇨🇳 中文说明

项目简介

GeoSource MCP 是一个基于 Model Context Protocol (MCP) 标准的数据服务程序。它让各类支持 MCP 的 AI 工具(如 Claude Desktop、Cursor 等)能够直接连接并检索本地结构化索引的 2,198+ 个全球真实 GIS 空间服务 与 1,561+ 个地图图层。

生态认证:本项目已通过全球领先的 Glama MCP Registry 自动化构建、运行与代码安全审计,已正式审核通过(Approved)上线收录。

解决什么问题?

在编写地图代码(如 Leaflet、OpenLayers、Mapbox)或处理空间数据时,大模型自身通常没有收录全球公开的地图服务地址,容易产生“幻觉”并生成错误链接。如果直接把几十万字的数据文件塞入 Prompt,不仅极其昂贵而且每次响应变慢。

GeoSource MCP 将整理好的本地 SQLite 数据库接入 MCP 接口,AI 在需要寻找数据源时,可以通过结构化接口直接查询真实的可用服务(覆盖 OGC WMS、WFS、WMTS、XYZ 瓦片、ArcGIS REST、STAC 等)。

核心优势与技术指标

  • 0.05 秒级响应:本地 SQLite 倒排与联合索引,毫秒级即刻返回检索结果。

  • 节省 99% 以上 Token:每次交互仅提取最相关的 35 条记录(约 200500 Tokens),杜绝大文件塞入 Prompt 的高额开销。

  • 杜绝接口幻觉:返回的端点 URL、图层名、免 Key 属性均经过真实验证,保证代码中的图层可直接加载。

  • 双向数据同步:支持 Excel 表格与 SQLite 双向同步,并提供接口允许 AI 在使用中自动更新失效链接。

包含的数据内容

  • 2,198+ 项主服务记录:涵盖各国测绘机构、开放政府数据、高程/地形 DEM、卫星影像、交通、气象与环境数据等。

  • 1,561+ 个子图层:记录具体服务下属的图层名称,方便直接配置进代码。

  • 50 余项属性字段:服务协议、所属国家、数据格式、是否免费、是否需 Key、商业使用许可等。
