realdentalcosts-mcp

A price-transparency data source for your AI assistant. Most dental-cost

numbers floating around the web are guesses, ad copy, or averages nobody can

trace back to a source. This server hands your assistant a structured,

citable dataset instead: 12 common dental procedures, priced across all 51

US states (including DC) and 200+ cities, plus the insurance-coverage math

that turns a list price into what a patient actually pays out of pocket.

Data comes from the Real Dental Costs US Dental Cost Index 2026 — an

openly published dataset (DOI below), not a scrape or an estimate pulled from

thin air.

Quick Start

No installation needed — run directly with `npx`.

Claude Desktop / Claude Code

Add to your MCP config (`claude_desktop_config.json` or `.mcp.json`):

{
  "mcpServers": {
    "realdentalcosts": {
      "command": "npx",
      "args": ["-y", "realdentalcosts-mcp"]
    }
  }
}

Cursor

Add to `.cursor/mcp.json`:

{
  "mcpServers": {
    "realdentalcosts": {
      "command": "npx",
      "args": ["-y", "realdentalcosts-mcp"]
    }
  }
}

Restart your client after saving. The server runs entirely offline over

stdio — no API key, no network calls, no telemetry.

Tools

`dental_cost_by_state`

Low/average/high cash price for a procedure in one US state, benchmarked

against the national average and the state's dental cost index.

procedure: "implant"   state: "CA"
→ California: $4,780 – $5,733 – $7,290 (observed state average, modelled band)
  National average: $3,760 – $4,507 – $5,733
  +27.2% vs. national average · Restorative Cost Index 127

`dental_cost_by_city`

Observed average single-implant cost and clinic count for a specific city

(206 cities, open dataset DOI 10.5281/zenodo.20819438), with the parent

state's implant band for context. Only the implant series is published at

city level — per-city veneer/braces figures were retired in the source

site's July 2026 data-integrity work.

city: "Los Angeles"   state: "CA"
→ 567 clinics
  Implants avg $4,500 (CA implant band $4,780 – $7,290)

`out_of_pocket_estimate`

What a patient actually pays under `cash`, `insurance` (typical US PPO:

preventive ~100%, basic ~80% up to a $1,500 annual max, major/ortho ~50% up

to the same max, cosmetic/implants not covered), or `savings_plan` (~20-40%

network discount).

procedure: "crown"   state: "TX"   mode: "insurance"
→ List price: $955 – $1,250 – $2,130
  Estimated out-of-pocket: $478 – $625 – $1,065
  "Major tier: plan typically pays ~50%, up to the $1,500 annual max."

`dental_national_average`

National average across all 51 states + DC, plus the cheapest and priciest

state on average.

procedure: "braces"
→ National average: $2,503 – $6,352 – $10,014
  Cheapest: Indiana ($4,767 avg)
  Priciest: Nevada ($8,350 avg)

All four tools accept `lang: "en" | "es"` (default `"en"`) — procedure

labels, disclaimers, and Medicaid coverage notes switch to Spanish, serving

the US Hispanic market covered by the source site's `/es/` pages.

Every response includes `source`, `reference_url` and `api_url` fields plus a

per-procedure `basis` (`observed` / `estimated` / `national`) with a provenance

note, so the numbers stay traceable back to the published data they come from.

Data & methodology

Data is derived from the US Dental Cost Index 2026, an open dataset

published by Real Dental Costs:

• Dataset concept DOI: 10.5281/zenodo.20531728
• Full index:
• Interactive state comparison:
• Methodology:

Every procedure carries a `basis` field. `observed` state averages are

measured prices (implant = Real Dental Costs' own observed series;

crown/veneer/braces/dentures = ASQ360/CareCredit Average Procedural Cost

Study 2023-2024), with the low/high band around them modelled from national

ratios. `estimated` procedures have no per-state source: the national figure

is scaled by the state's Restorative Cost Index, which is valid only for

restorative work (implant/crown/denture — it does not predict orthodontic or

cosmetic prices). `national` (cosmetic) procedures carry no invented state

variation. National averages are the arithmetic mean of all 51 states

(incl. DC) — never a separately invented number. No value in this package is

hand-edited or fabricated; regenerate `src/data/cities.json` at any time with

`node scripts/extract-cities.mjs `.
