MyLeadTech MCP

HVAC MCP server — fault codes, model lookup and answers cited to the OEM manual page.

This repository holds the connection details and registry metadata for the hosted MyLeadTech MCP server. There is no server code here: the server runs at the endpoint below.

  • Endpoint: https://mcp.myleadtech.app/mcp/
  • Transport: Streamable HTTP
  • Auth: API key from the MyLeadTech dashboard, sent as Authorization: Bearer <api_key>. The site also lists OAuth sign-in with a MyLeadTech account for clients that support it.
  • Brands served: Carrier, Trane, Lennox
  • Sandbox: 100 free units a month. Equipment lookups and clarifying questions don't count. A retried request with the same idempotency key is never charged twice.

Tools

ToolWhat it doesParameters
resolve_equipmentTurns a model or nameplate reference into brand and equipment, and reports coverage. Not charged.reference, market (default us), language (default en-US)
search_hvac_documentsFinds passages and citations in manufacturer documents.question, brand, model_reference, fault_code, language, limit (default 5), operation_id
get_hvac_sourceReturns a cited passage with bounded context.source_id
answer_hvac_questionA written answer with numbered, page-level sources.question, brand, model_reference, fault_code, language, limit (default 5), operation_id
get_hvac_document_pageA source page as PNG, or a signed single-page PDF link when format is pdf.document_version_id, page_number, format (default png), region

operation_id makes a retry replay the earlier result instead of charging again.

Install

Create an API key in the dashboard first.

Claude Code
claude mcp add --transport http myleadtech https://mcp.myleadtech.app/mcp/ --header "Authorization: Bearer YOUR_API_KEY"

Without --header, Claude Code can sign you in with your MyLeadTech account instead.
