What Costumbre (Custom) is for

"Costumbre" is the Spanish word for a custom or habit. This connector is a fully local Spanish social customs and etiquette guide — the everyday rhythms, greetings and unwritten rules that come up whenever a visitor, newcomer or business contact interacts with Spanish culture — gathered in one place and, where a practice has genuinely shifted over time (the siesta above all), described with that nuance rather than as a fixed, timeless stereotype.

What it does

A single custom's description and significance, across seven everyday customs — siesta, sobremesa, paseo, dos besos, Sunday family lunch, tapeo, and late meal times (custom_info); a keyword search across those customs (custom_search); the typical Spanish meal schedule — breakfast, lunch around 2-3pm, an afternoon merienda, dinner around 9-10pm or later — contrasted with earlier northern-European/US mealtimes (meal_time_guide); formal (handshake) vs. informal (dos besos) greeting conventions, who typically initiates, and a regional variation note (greeting_guide); general tendencies around social vs. business punctuality, explicitly caveated as tendencies rather than fixed traits (punctuality_norms); general gift-giving norms for home visits, celebrations and business contexts (gift_giving_etiquette); general business etiquette — greeting customs, business-meal conventions, and the emphasis on relationship-building (business_etiquette); a region's overview and distinctive cultural/linguistic notes for Catalonia, the Basque Country (Euskadi), Andalusia, or Galicia (regional_custom_variation); and a glossary of about ten core terms — sobremesa, paseo, tapeo, siesta, propina, dos besos, and more (etiquette_glossary).

What it is not

Not a stereotype checklist. Spain is culturally diverse by region, generation, city size and setting, and a number of once-common practices have genuinely changed — the siesta as an actual midday nap has declined sharply in most urban workplaces, and punctuality norms vary a great deal by context rather than being a fixed national trait. This connector says so explicitly rather than presenting either as settled fact. It also does not take any position on regional independence or self-governance movements mentioned in the regional notes for Catalonia, the Basque Country or Galicia — those are described strictly as facts of each region's public life, not as arguments for or against any political outcome.

Tools

Everyday Customs

custom_info — A single Spanish social custom's description and significance, plus a modern-day note where a once-common practice (like the siesta) has genuinely shifted. Covers siesta, sobremesa, paseo, dos besos, Sunday family lunch, tapeo, and late meal times. Use for "what is sobremesa", "is the siesta still practiced", "what is tapeo". Args: name.

custom_search — Search Spanish social customs by keyword across their name, category, summary and description. Use for "which customs involve eating", "find customs about greetings". Args: query.

Daily Life

meal_time_guide — The typical Spanish meal schedule — breakfast, lunch (often 2-3pm), an afternoon merienda, and dinner (often 9-10pm or later) — contrasted with earlier northern-European/US mealtimes. A genuine, well-documented cultural difference. Use for "what time do people eat dinner in Spain", "when is lunch in Spain".

greeting_guide — Formal (handshake) vs. informal (dos besos) greeting conventions, who typically initiates, and a regional variation note. Pass a context to get just that one, or omit it for both. Use for "how do you greet someone in Spain", "do you shake hands or kiss in a Spanish business meeting". Args: context.

punctuality_norms — General tendencies around social vs. business punctuality in Spain, with an explicit caveat that these vary by region, generation and setting rather than being a fixed national trait. Use for "are Spaniards punctual", "is it okay to be late to a party in Spain".

Etiquette

gift_giving_etiquette — General Spanish gift-giving norms for home visits, celebrations and business contexts — what's common, what to avoid (like chrysanthemums), and how modest business gift-giving typically is. Use for "what should I bring to a Spanish dinner party", "is gift-giving common in Spanish business".

business_etiquette — General Spanish business etiquette — professional greeting customs, business-card and meeting norms, typical business-meal conventions, and the emphasis on relationship-building before deals move forward. Use for "what's business etiquette like in Spain", "how long do Spanish business lunches run".

Reference

regional_custom_variation — A Spanish region's overview and distinctive cultural/linguistic notes — Catalonia, the Basque Country (Euskadi), Andalusia, or Galicia. Regional and linguistic facts are described factually and respectfully; where a region has a notable regional-identity or self-governance movement, that is stated as a fact of its public life without taking any political position. Use for "what's different about Catalonia", "tell me about Basque culture". Args: region.

etiquette_glossary — Definitions of common Spanish social/etiquette terms (sobremesa, paseo, tapeo, siesta, propina, dos besos, and more). Use for "what does sobremesa mean", "what's propina". Args: term.

Costumbre (Custom) — Privacy Policy

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

What Costumbre (Custom) is. Costumbre (Custom) is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for a fully local Spanish social customs and etiquette guide — everyday customs, meal times, greetings, punctuality norms, gift-giving and business etiquette, regional variation, 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 custom name or search keyword, a greeting context, a region 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 bundled, hand-authored reference files 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.

Not professional or political advice. This connector is a cultural reference and etiquette guide, not legal, business or travel advice, and it does not take a position on any political question — including regional independence or self-governance movements mentioned in its regional notes.

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

Costumbre (Custom) — Terms of Service

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

1. The Service. Costumbre (Custom) returns a fully local Spanish social customs and etiquette guide — everyday-custom descriptions and significance; a meal-time guide; a greeting guide; punctuality tendencies; gift-giving and business etiquette; regional variation notes; and a glossary. It is accessed through an AI assistant or directly over MCP or HTTP.
2. Cultural reference, not a universal rule. Spanish social custom varies significantly by region, generation, city size and setting. Content here reflects commonly documented convention, hand-authored by the publisher, and is offered as a general reference — not a claim that any single practice described is universal, mandatory, or followed by every person, family or company. Several entries specifically note where a once-common practice (notably the siesta) has genuinely declined, and punctuality guidance is explicitly framed as a tendency rather than a fixed trait.
3. No political position. Regional notes describe linguistic and cultural facts, including the existence of regional-identity or self-governance movements in Catalonia, the Basque Country and Galicia, strictly as facts of each region's public life. The Service takes no position on independence or any other political question, and nothing in it should be read as advocacy for or against any outcome.
4. Not professional advice. Guidance here is not legal, business, travel or etiquette-consulting advice, and is not a substitute for local, first-hand knowledge or professional counsel for a specific situation.
5. Acceptable use. Automated use within the published rate limits is welcome.
6. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
7. Data. Our Privacy Policy describes what we process. In short: your query is answered from bundled reference files, and nothing is stored.
8. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
9. 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.
10. Governing law. California law; venue in San Mateo County, California.
