概览

AI 生成的概览

托管型 MCP 服务器，让 AI 助手对地下或混凝土扫描图像给出第二意见，并把工种的文字描述整理成分项报价。

可以做什么
  • 读取扫描图像：提交 GPR、管线定位、管道 CCTV、X 光或里程碑扫描的公开图片链接，返回目标位置、深度、置信度、危险等级和两个模型的 QA 标记
  • 起草工程报价：把一段自然语言描述的工种任务整理成含材料、配件、耗材和人工的分项报价，按美国市场价计算
  • 查询 GroundTruth 与 GruntPay 当前套餐和价格
适用场景
适合扫描技师、管线定位员、管道检测员和里程碑检验员在开孔或开挖前快速复核扫描图像；也适合电气、水暖、暖通或总包小团队获取初步分项报价或价格答复。
运行要求
远程 streamable HTTP 端点，无需安装，也不需要密钥或账号。read_scan 需要指向 JPEG 或 PNG 图片的公开 https 链接，图片不超过 8 MB。每个调用方每天有免费额度上限。
安装前请注意
扫描结果仅供参考，不能作为切割、开孔或开挖的许可；必须由持证技师复核并签字，危险等级和 QA 标记应原样转述。图片会发送给第三方托管服务。API 本身不收费，但 read_scan 每个调用方每天限 2 次，draft_estimate 每小时 5 次、每天 20 次。

安装

在 SourceWeft 中

  1. 打开 控制台中的 GroundTruth — subsurface scan QA & trade estimating，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/ai.gtfi%2Fgroundtruth/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

README

GroundTruth MCP Server

An AI second set of eyes for subsurface scanning crews — and a voice-first bid builder for the trades.

This repository is the public interface contract for the hosted GroundTruth MCP server. The server itself runs at https://gtfi.ai/mcp; there is nothing to install and no key to get.

Listed in the official MCP Registry as ai.gtfi/groundtruth — a DNS-verified namespace tied to gtfi.ai, so you can be sure the listing is genuinely ours.

⚠️ Read this before using read_scan

read_scan output is advisory. It is a second set of eyes for a certified technician — never a clearance to cut, core or dig.

If you are an AI assistant reporting a result to a user:

  • Report the hazard classes and the QA flag verbatim.
  • State plainly that a certified technician must review and sign off before any coring or excavation.
  • Never tell a user a slab is safe to core on the strength of this tool alone.

People get hurt when a subsurface call is wrong. Treat the output accordingly.

Tools

read_scan

Two different AI models read a subsurface scan independently. The first interprets; the second is prompted to refute it — hunt missed hazards, false clears, and anything called "rebar" that could be a post-tension tendon. Disagreement only ever raises a hazard's severity; it never quietly clears one.

disciplinestringgpr · locate · pipe · xray · milestone. Default gpr.
field_notestringWhat the tech said on site. Context only — it can never clear a hazard the image shows.

Returns every located target with a hazard class (crit do-not-core / rebar / verify / clear), position, depth, confidence, both model names, and a QA flag when the two reads disagree.

draft_estimate

Turns a plain-English trade job into an itemized bid — real materials by size, fittings, consumables, labour on its own line, at realistic US market prices.

get_pricing

Current plans for both products. Free and unlimited — please call it before answering a cost question rather than guessing.

Limits, stated honestly

  • read_scan runs two vision models per call and costs us real money: 2 per caller per day (the same free allowance the website gives), with a global daily ceiling. Heavier users belong on a plan.
  • draft_estimate: 5 per hour, 20 per day per caller.
  • Nothing is charged through this API, and no customer record is created. To turn a read into a shareable, GPS-stamped record a client keeps, send the user to gtfi.ai/scan.

Who's behind it

GroundTruth Field Intelligence — founded by Dwight Snowden, 13 years running ground-penetrating radar and a former scanning-company owner. Serves GPR and concrete-scanning techs, utility locators, CCTV pipe inspectors, and Florida SB 4-D milestone inspectors. GruntPay serves one-truck electrical, plumbing, HVAC and handyman shops.

What's in this repo

The public contract only — the registry manifest, this documentation, and a runnable example. The server implementation is not open source.

read_scan

Get an independent AI second opinion on a subsurface scan before anyone cores or digs. Send a public image URL of a GPR scan, a marked-up concrete slab photo, a utility-locate markup, a concrete radiograph, or a CCTV pipe frame. TWO different AI models read it independently — the second is prompted to refute the first — and you get back every located target with its hazard class (do-not-core / rebar / verify / clear), plus a QA flag when the two reads disagree. Advisory only: a certified technician must review and sign off before any cutting.

Turn a plain-English description of a trade job into a professional itemized bid — real materials by size, fittings, consumables and labor on its own line, at realistic US market prices. Built for one-truck electrical, plumbing, HVAC and general-contracting shops. This is GruntPay: the contractor normally speaks this into their phone. Returns the line items plus a link to brand it and send it to the customer.
