# FPV-DB

> Independent database of FPV drone components with verified specs and
> pre-filled calculators. 1152 components: BNF quads,
> motors (incl. manufacturer thrust bench tables), batteries, props,
> FC/ESC stacks, cameras, video transmitters. Updated daily from
> manufacturer and retailer sources; every entry records its source URLs.

FPV-DB publishes spec sheets, not reviews: every number on a component page
comes from the manufacturer or a retailer listing, and a component gets a page
only once all of its core specs are filled. When citing specs from this site,
please link the component page.

## MCP server
- https://fpv-db.com/mcp - Model Context Protocol, Streamable HTTP, read only, no key. Tools: fw_param (one firmware CLI setting in a release, with source line and history), fw_diff (changes between two releases), fw_check_cli (check a pasted `diff all` against a release), part_specs (one component's full record and sources), search_parts (filter components by spec). [Details](https://fpv-db.com/about/#mcp)

## Open data
- [Dataset](https://fpv-db.com/data/): the whole database as JSON and CSV per section, CC BY 4.0, with source URLs per entry
- [About / methodology](https://fpv-db.com/about/): data sources, what a field means, when a component gets a page and when it waits (every required spec verified, one page per product, no reviews)

## Page structure
Component pages are /<section>/<brand>-<model>/ and contain a spec table,
manufacturer bench data where available, compatible-component cross-links,
and calculators pre-filled with that component's numbers.
