scanverdict

Would you core that slab on one AI's say-so? scanverdict is a local stdio bridge to the hosted GroundTruth MCP service, which gives subsurface scanning crews a second set of eyes: two different AI models read a GPR, locate, pipe, or X-ray scan independently — the first interprets, the second is prompted to refute it — plus a voice-first bid builder for the trades and a pricing lookup.

Safety first: a read_scan result is advisory only. It is never a clearance to cut, core, or dig, and a certified technician must review and sign off before any coring or excavation. Disagreement between the two reads only ever raises a hazard's severity; it never quietly clears one.

The hosted endpoint is https://gtfi.ai/mcp (no authentication). This package runs locally as a stdio MCP server and forwards each tool call to that endpoint as JSON-RPC. Point it elsewhere with the GROUNDTRUTH_MCP_URL environment variable.

Documented upstream limits: read_scan runs two vision models per call and is limited to 2 per caller per day (with a global daily ceiling); draft_estimate allows 5 per hour and 20 per day per caller. Nothing is charged through the API.

CLI

npx @reneturcios/scanverdict read-scan https://example.com/scan.jpg --discipline gpr --field-note "NW corner"
npx @reneturcios/scanverdict draft-estimate "Replaced the panel, 85 feet of conduit, 8 can lights, 16 hours" --trade electrical
npx @reneturcios/scanverdict pricing
npx @reneturcios/scanverdict --version

Output is the upstream result as JSON. Exit codes: 0 on success, 1 on a runtime error (including an upstream failure), 2 on a usage error.

  • discipline (string, optional) — one of gpr, locate, pipe, xray, milestone; default gpr

  • field_note (string, optional) — what the tech said on site; context only, it can never clear a hazard the image shows

• draft_estimate — Turns a plain-English trade job into an itemized bid at realistic US market prices.

  • job_description (string, required) — the job in plain English

  • trade (string, optional) — one of electrical, plumbing, hvac, general
