AVentTech x402 MCP Server

AV/IT device integration knowledge, sold to AI agents. $0.03 per answer. No API keys, no signups.

AVentTech P.C. is a professional systems integrator (Crestron, Lutron, KNX — superyachts, hotels, auditoriums) in Athens, Greece. Twenty years of commissioning knowledge — control protocols, ports, and the field-tested gotchas that cost an integrator a day on site — published as a machine-payable API on the x402 protocol: agents pay per lookup in USDC on Base.

This repo is the MCP server that puts those tools inside Claude Desktop, Claude Code, Cursor, or any MCP client.

What it does

avt_device_catalog

free

Full list of every make/model in the KB — check coverage before buying

avt_device_lookup

$0.03

Control protocol, transport, TCP/UDP port, field-tested integration notes

avt_fx_rates

$0.002

Payment happens automatically via x402 (HTTP 402 → signed USDC payment → data). Fund a small dedicated buyer wallet and pass it as AVT_BUYER_PRIVATE_KEY. Without a key, the free catalog tool still works.
