## What it does

The server operates over Streamable HTTP. No server code is stored in the repository: calls go directly to `https://mcp.myleadtech.app/mcp/`. The service connects assistants to technical documentation for Carrier, Trane, and Lennox equipment. It locates manual passages, decodes fault codes, and cites precise page numbers.

Available tools include `resolve_equipment`, `search_hvac_documents`, `answer_hvac_question`, and page exports in PNG or PDF. Retrying queries with the same `operation_id` returns the cached response. This avoids double billing on retries.

Requests fail without an API key from `web.myleadtech.app`, unless the client supports OAuth login. The developer sandbox provides 100 free units each month. Resolving equipment models does not consume monthly credits.

## Requirements
- Remote server: `https://mcp.myleadtech.app/mcp/`

## When to use it
- look up HVAC fault codes across manufacturer documentation
- identify exact equipment series from a nameplate string
- extract verified manual passages with page citations
- pull schematic pages as PNG images or PDF links

## Example prompts
- What refrigerant type is specified for the Carrier 27TPA8 heat pump?
- Check this Trane error code and show the relevant manual page.
- Look up Lennox equipment details using model tag 13HPX.
