Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@MyLeadTech MCPWhat fault code E4 mean on a Trane XR15?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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
Tool | What it does | Parameters |
| Turns a model or nameplate reference into brand and equipment, and reports coverage. Not charged. |
|
| Finds passages and citations in manufacturer documents. |
|
| Returns a cited passage with bounded context. |
|
| A written answer with numbered, page-level sources. |
|
| A source page as PNG, or a signed single-page PDF link when |
