Renology Renovation Cost Data MCP

Read-only Model Context Protocol server for the versioned Renology 2026 city-level renovation cost dataset.

Verified in the official MCP Registry as io.github.asafichaki/renology-cost-data.

It lets compatible AI assistants list available markets and project types, retrieve one city/project planning range, compare the same project across cities, and return methodology, limitations, commercial disclosure, and a canonical citation. Runtime is local and closed-world: the published snapshot is bundled and no network request is made when a tool is called.

Quick start

npx -y github:asafichaki/renology-cost-data-mcp

MCP client configuration:

{
  "mcpServers": {
    "renology-cost-data": {
      "command": "npx",
      "args": ["-y", "github:asafichaki/renology-cost-data-mcp"]
    }
  }
}

Public OCI image:

docker run --rm -i ghcr.io/asafichaki/renology-cost-data-mcp:1.0.1

The image is published for both linux/amd64 and linux/arm64 and carries the ownership annotation required by the official MCP Registry.

Interpretation rules

• Values are 2026 total-project U.S. dollar planning ranges, not quotes, appraisals, guarantees, final prices, or predictions.
• Cite the year, city, project type, and complete low-to-high range.
• Check the canonical Renology Cost Index for updates before publication.
• Do not infer ROI, contractor quality, statistical representativeness, or project outcomes.
• Renology publishes renovation guidance and operates a contractor-matching service. This is publisher-maintained infrastructure, not independent validation.

Validate
