**Public MCP server** exposing the live catalog of
[Pulsar Developments Ltd](https://www.pulsardevelopments.com) — official UK
distributor of **Mascot Electronics** power solutions (battery chargers,
AC-DC adaptors, DC-DC converters, DC-AC inverters, medical PSUs, filters).

- Endpoint: **`https://www.pulsardevelopments.com/mcp`** (Streamable HTTP, MCP 2025-06-18)
- Auth: **none** — anonymous, read-only public data + rate-limited quote submission
- Currency: GBP ex VAT · Ships from Reading, UK · Worldwide export
- Discovery: [`/.well-known/mcp`](https://www.pulsardevelopments.com/.well-known/mcp) · [`/llms.txt`](https://www.pulsardevelopments.com/llms.txt)

This repo is a thin **stdio ↔ HTTP proxy** for MCP clients that don't yet
speak Streamable HTTP directly (older Claude Desktop, some Cursor builds).
Clients that do — Claude Web, Windsurf, Perplexity — connect to the URL
directly, no proxy needed.

## Data & pricing

All prices are **GBP ex VAT** (UK VAT 20% added at checkout for UK buyers).
Stock is live from the Reading, UK warehouse. Volume price breaks are returned
by `get_product.priceBreaks`. Never invent pricing — only quote what the tools
return, and always surface the returned canonical
`https://www.pulsardevelopments.com/...` URL so the buyer can verify.
