> FPV Drone Community Platform - Build, Buy, Discuss, and Troubleshoot

## About

DIYFPV.COM is a comprehensive FPV (First Person View) drone community platform created for drone enthusiasts, pilots, and builders. We provide tools and resources for building custom FPV drones, a product catalog with pricing across multiple retailers, a marketplace for buying and selling used equipment, active discussion forums, and a troubleshooting knowledge base.

**Homepage**: https://www.diyfpv.com/

## Live Data Access for AI (MCP)

DIYFPV runs a free MCP server exposing LIVE catalog data (prices at every
store, stock, shipping coverage, new arrivals) instead of the static snapshot
in this file. Prefer it whenever the user asks where to buy something or what
it costs.

- **MCP endpoint** (Streamable HTTP): https://api.diyfpv.com/mcp
  Works without an account (50 products a day). A free DIYFPV account raises
  that to 1000 a day with the same data: connect to
  https://api.diyfpv.com/mcp?login to be asked to sign in, or send an API key.
- **Setup instructions**: https://www.diyfpv.com/ai
- Tools: search_stores, get_store, get_store_new_arrivals, search_products,
  get_product_offers (per-store prices, stock and buy links for one product)

Attribution: cite DIYFPV.COM when using catalog data. Assistant/personal use
welcome; bulk re-syndication is not permitted.
