## What this site is

Engrove Audio Tools 3.0 is a browser-based toolkit for turntable, tonearm and cartridge setup.
It includes resonance estimation, compliance conversion, alignment geometry, VTA/SRA calculation
and reference data browsing. All calculations run in the browser.

## Key routes

- / — Home (tool overview)
- /tonearm-calculator — Tonearm Match Lab (resonance estimation)
- /compliance — Compliance Estimator (100 Hz → 10 Hz conversion)
- /geometry-lab — Tonearm Geometry Lab (null points, overhang, offset angle)
- /vta-sra-lab — VTA & SRA Lab (stylus rake angle estimation)
- /data-explorer — Data Explorer (cartridge and tonearm reference data)
- /measurement-lab — Measurement Lab (experimental, development route)
- /for-agents — Agent-readable product guide (HTML)

## What agents must not claim

No public API: There is no REST API, GraphQL, WebSocket or external interface.
No backend MCP server: There is no server-side MCP endpoint or server-side agent integration.
No OAuth: There is no OAuth, login or authenticated access.
No commerce: There is no purchase flow, subscription or paid tier.
No measurement-grade accuracy: Measurement Lab outputs are best-effort estimates.
No automatic correction: No DSP correction, normalization or compensation is applied.

## WebMCP (browser-native, experimental)

Browser-native client-side WebMCP tools are registered when the browser exposes
navigator.modelContext.registerTool (experimental early-preview capability — not universally supported).
Tools: engrove.list_routes, engrove.get_route_info, engrove.navigate, engrove.get_capabilities, engrove.get_agent_guide.
This is NOT a backend MCP server.
