Public MCP server exposing the live catalog of Pulsar Developments Ltd — 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 · /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.
