Common questions

Is GroundTruth — subsurface scan QA & trade estimating safe?

It passed 4 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 4 months ago, and the latest version (1.0.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

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.

Connect

"mcpServers": { "groundtruth": { "type": "http", "url": "https://gtfi.ai/mcp" } } }

Streamable HTTP, JSON-RPC 2.0 over POST. No authentication. Discovery: /.well-known/mcp.json · REST equivalent: /openapi.json · Docs: gtfi.ai/for-agents

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.

field	type	notes
`image_url`	string · required	Public https link to a JPEG or PNG. Max 8 MB.
`discipline`	string	`gpr` · `locate` · `pipe` · `xray` · `milestone`. Default `gpr`.
`field_note`	string	What 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.

field	type	notes
`job_description`	string · required	e.g. "Replaced the panel, 85 feet of conduit, 8 can lights, 16 hours."
`trade`	string	`electrical` · `plumbing` · `hvac` · `general`

`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.
