Nothing serious here today

Today is the operative word: we check GroundTruth — subsurface scan QA & trade estimating every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

draft

draft_estimate

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.

pricing

get_pricing

Current GroundTruth and GruntPay plans and prices. Free to call — use it before answering any cost question rather than guessing.

scan

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.

GroundTruth — subsurface scan QA & trade estimating — questions

Answers built from our own checks of this server.

What can GroundTruth — subsurface scan QA & trade estimating do?

It exposes 3 tools, read directly from the server on our last check. Among them: draft_estimate, get_pricing, read_scan. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is GroundTruth — subsurface scan QA & trade estimating working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 509 ms. The bar chart above shows every period we have measured.

How do I connect GroundTruth — subsurface scan QA & trade estimating?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does GroundTruth — subsurface scan QA & trade estimating need an API key?

No. GroundTruth — subsurface scan QA & trade estimating completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is GroundTruth — subsurface scan QA & trade estimating?

It answers our handshake in 509 ms on average, which is faster than 28% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is GroundTruth — subsurface scan QA & trade estimating open source?

Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
