This server hands your assistant a structured,\ncitable dataset instead: 12 common dental procedures, priced across all 51\nUS states (including DC) and 200+ cities, plus the insurance-coverage math\nthat turns a list price into what a patient actually pays out of pocket.\n\nData comes from the **Real Dental Costs US Dental Cost Index 2026** — an\nopenly published dataset (DOI below), not a scrape or an estimate pulled from\nthin air.\n\n## Quick Start\n\nNo installation needed — run directly with `npx`.\n\n### Claude Desktop / Claude Code\n\nAdd to your MCP config (`claude_desktop_config.json` or `.mcp.json`):\n\n```json\n{\n \"mcpServers\": {\n \"realdentalcosts\": {\n \"command\": \"npx\",\n \"args\": [\"-y\", \"realdentalcosts-mcp\"]\n }\n }\n}\n```\n\n### Cursor\n\nAdd to `.cursor/mcp.json`:\n\n```json\n{\n \"mcpServers\": {\n \"realdentalcosts\": {\n \"command\": \"npx\",\n \"args\": [\"-y\", \"realdentalcosts-mcp\"]\n }\n }\n}\n```\n\nRestart your client after saving. The server runs entirely offline over\nstdio — no API key, no network calls, no telemetry.\n\n## Tools\n\n### `dental_cost_by_state`\n\nLow/average/high cash price for a procedure in one US state, benchmarked\nagainst the national average and the state's dental cost index.\n\n```\nprocedure: \"implant\" state: \"CA\"\n→ California: $4,780 – $5,733 – $7,290 (observed state average, modelled band)\n National average: $3,760 – $4,507 – $5,733\n +27.2% vs. national average · Restorative Cost Index 127\n```\n\n### `dental_cost_by_city`\n\nObserved average single-implant cost and clinic count for a specific city\n(206 cities, open dataset DOI 10.5281/zenodo.20819438), with the parent\nstate's implant band for context. Only the implant series is published at\ncity level — per-city veneer/braces figures were retired in the source\nsite's July 2026 data-integrity work.\n\n```\ncity: \"Los Angeles\" state: \"CA\"\n→ 567 clinics\n Implants avg $4,500 (CA implant band $4,780 – $7,290)\n```\n\n### `out_of_pocket_estimate`\n\nWhat a patient actually pays under `cash`, `insurance` (typical US PPO:\npreventive ~100%, basic ~80% up to a $1,500 annual max, major/ortho ~50% up\nto the same max, cosmetic/implants not covered), or `savings_plan` (~20-40%\nnetwork discount).\n\n```\nprocedure: \"crown\" state: \"TX\" mode: \"insurance\"\n→ List price: $955 – $1,250 – $2,130\n Estimated out-of-pocket: $478 – $625 – $1,065\n \"Major tier: plan typically pays ~50%, up to the $1,500 annual max.\"\n```\n\n### `dental_national_average`\n\nNational average across all 51 states + DC, plus the cheapest and priciest\nstate on average.\n\n```\nprocedure: \"braces\"\n→ National average: $2,503 – $6,352 – $10,014\n Cheapest: Indiana ($4,767 avg)\n Priciest: Nevada ($8,350 avg)\n```\n\nAll four tools accept `lang: \"en\" | \"es\"` (default `\"en\"`) — procedure\nlabels, disclaimers, and Medicaid coverage notes switch to Spanish, serving\nthe US Hispanic market covered by the source site's `/es/` pages.\n\nEvery response includes `source`, `reference_url` and `api_url` fields plus a\nper-procedure `basis` (`observed` / `estimated` / `national`) with a provenance\nnote, so the numbers stay traceable back to the published data they come from.\n\n## Open JSON API (no MCP required)\n\nThe same data this MCP server exposes is also available as a **free, open JSON API** —\nstatic versioned endpoints, no key, CORS enabled, documented with an OpenAPI 3.1 spec:\n\n- Docs: \n- Metadata & DOIs: \n- All 51 state markets: \n- One state: \n- The 12 procedures: \n- One procedure across states: \n- OpenAPI 3.1 spec: \n\nLicense **CC BY 4.0** — attribution required: link to or cite\nDOI [10.5281/zenodo.20531728](https://doi.org/10.5281/zenodo.20531728).\n\n## Data & methodology\n\nData is derived from the **US Dental Cost Index 2026**, an open dataset\npublished by [Real Dental Costs](https://realdentalcosts.com):\n\n- Dataset concept DOI: [10.5281/zenodo.20531728](https://doi.org/10.5281/zenodo.20531728)\n- Full index: \n- Interactive state comparison: \n- Methodology: \n\nEvery procedure carries a `basis` field. `observed` state averages are\nmeasured prices (implant = Real Dental Costs' own observed series;\ncrown/veneer/braces/dentures = ASQ360/CareCredit Average Procedural Cost\nStudy 2023-2024), with the low/high band around them modelled from national\nratios. `estimated` procedures have no per-state source: the national figure\nis scaled by the state's Restorative Cost Index, which is valid only for\nrestorative work (implant/crown/denture — it does not predict orthodontic or\ncosmetic prices). `national` (cosmetic) procedures carry no invented state\nvariation. National averages are the arithmetic mean of all 51 states\n(incl. DC) — never a separately invented number. No value in this package is\nhand-edited or fabricated; regenerate `src/data/cities.json` at any time with\n`node scripts/extract-cities.mjs `.\n\n## Disclaimer\n\nThis package provides **market research pricing data** — not medical advice,\nnot a quote, and not a guarantee of what any specific dentist will charge.\nActual prices vary by clinic, provider, insurance plan, and case complexity.\nAlways confirm pricing directly with a licensed dental provider before\ntreatment.\n\n## License\n\nMIT © [tresor4k](https://github.com/tresor4k)\n",
