Home Repairs Estimator MCP

Provides deterministic cost calculators for home services including HVAC, roofing, plumbing, electrical, solar, and water heaters. It allows AI agents to estimate replacement, repair, or installation costs based on specific parameters like home size, system type, and material, without requiring user signup or collecting PII.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http home-repairs-estimator-mcp https://homerepairsestimator.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add home-repairs-estimator-mcp --url https://homerepairsestimator.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable home-repairs-estimator-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "home-repairs-estimator-mcp": {
      "url": "https://homerepairsestimator.com/mcp"
    }
  }

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration

  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start home-repairs-estimator-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "home-repairs-estimator-mcp": {
      "type": "http",

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http home-repairs-estimator-mcp https://homerepairsestimator.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
