Sonido (Sound)

What Sonido is for

The question that comes up whenever Mexican music comes up in conversation — what actually is norteño, where does banda come from, what's the difference between a ranchera and a corrido, what instrument gives mariachi that deep bass sound — answered from one hand-curated cultural and historical reference, not a music catalogue.

What it does

Origin/region, history, typical instrumentation, typical occasions and notable sub-styles for at least eight genres — mariachi, banda (banda sinaloense), norteño, ranchera, corrido, son jarocho, huapango (huasteco) and cumbia mexicana (genre_info, genre_search); which Mexican music genres are most associated with which region — mariachi and ranchera with Jalisco, banda with Sinaloa, norteño and corrido with the northern border states, son jarocho with Veracruz, huapango with the Huasteca region, and more (regional_origin_guide); a guide to at least eight instruments — guitarrón, vihuela, requinto jarocho, trompeta, accordion, bajo sexto, tololoche, marimba, tambora and jarana jarocha — their build, how they're played, their role and typical genre association (instrument_guide); the dance style paired with a genre where one exists, such as son jarocho and huapango's zapateado footwork or banda's quebradita (dance_style_guide); a fuller standalone history writeup for one genre (history_overview); a plain-words description of a genre's general structural conventions — verse-refrain, strophic storytelling or call-and-response — with no lyrics reproduced (song_structure_guide); the typical occasions and named festival traditions a genre is tied to — weddings, quinceañeras, serenatas, Independence Day, Día de los Muertos (festival_occasion_guide); and a glossary of about a dozen terms — mariachi, banda, norteño, corrido, ranchera, huapango, son, zapateado, requinto, guitarrón, vihuela, grito, fandango, quinceañera (music_glossary).

What it is not

Not a music catalogue, streaming service or artist directory — Sonido is a cultural and historical reference about the genres themselves. It names no specific living artists and quotes no song lyrics anywhere in its data. For tracks, albums, artist profiles, charts or a live discography, use a music catalogue connector instead. Fully local and keyless: nothing is fetched from any upstream source and nothing about a query is stored.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Sonido (Sound) — Privacy Policy

Effective 24 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Sonido is. Sonido (Sound) is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for a hand-curated Mexican music genre reference: genre profiles, an instrument guide, a regional map, dance-style pairings, standalone history writeups, song-structure conventions, a festival/occasion guide, and a glossary. You interact with your assistant; the assistant sends us only the arguments needed for that one lookup.

What we receive. The arguments of each tool call — a genre name, a search query, a region, an instrument name, or a glossary term — the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Everything is answered from a bundled, hand-curated reference file and nothing is stored. No request is forwarded to any third party — there is no upstream call at all, live or otherwise — and no query is logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant or your name, and we do not build a profile from your queries: each request is answered independently and nothing carries over between requests. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. None — the entire dataset is bundled with the server and answered locally. Hosting: Vercel (United States regions).

Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Sonido is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.

Sonido (Sound) — Terms of Service

Effective 24 September 2026. These terms govern use of the Sonido (Sound) connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

1. The Service. Sonido (Sound) returns a hand-curated Mexican music genre reference — genre profiles, an instrument guide, a regional map, dance-style pairings, standalone history writeups, song-structure conventions, a festival/occasion guide, and a glossary — hand-curated as a cultural and historical reference. It is accessed through an AI assistant or directly over MCP or HTTP.
2. A reference, not a catalogue. Sonido is an independent cultural and historical reference tool, not affiliated with or endorsed by any artist, label, ensemble, festival organizer or government body. It does not provide track, album or artist data, streaming links, or lyrics, and names no specific living artists. For music catalogue or streaming information, use a dedicated music connector instead.
3. A hand-curated reference. Content reflects general, widely-documented cultural and historical knowledge as curated at build time; it is not a substitute for academic or ethnomusicological research, and regional traditions vary and continue to evolve beyond what is captured here.
4. Acceptable use. Automated use within the published rate limits is welcome.
5. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
6. Data. Our Privacy Policy describes what we process. In short: your query is answered from a bundled reference file, and nothing is stored.
7. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
8. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss arising from use of or reliance on the Service. Our total liability is limited to US $100.
9. Governing law. California law; venue in San Mateo County, California.
