What Packlist is for

The packing-and-baggage questions that come up before every trip — what should I actually bring, will my bag be overweight, how big can my carry-on be on this airline, can I bring this bottle through security — answered from one fully local reference, without ten browser tabs of conflicting blog posts.

What it does

generate_packing_list builds a categorized packing list (clothing, toiletries, electronics, documents, health, plus activity-specific gear) for a trip type — business, leisure/beach, hiking/outdoor, winter-sports, backpacking, city-break or cruise — a duration and a climate, scaling clothing quantities sensibly by duration (capped, with a laundry-assumption note for longer trips) rather than literally packing one shirt per day. airline_baggage_rules gives hand-verified checked and carry-on baggage allowances for 24 major airlines across North America, Europe, the Middle East, Asia, India and Brazil; compare_baggage_allowance puts two side by side. liquids_rule_check applies the common international 3-1-1-style carry-on liquids rule to one item. weight_estimator sums a list of packed items' weights and flags whether the total is likely to exceed a stated or looked-up airline's checked-bag limit. climate_pack_adjustments gives clothing-layer guidance for a climate and season combination. document_checklist lists commonly-needed travel documents — passport, visa reminder, travel insurance, vaccination card, driver's license/IDP, booking confirmations — generically, by trip type. packing_cube_organizer groups a packed-item list into a chosen number of cubes using a real load-balancing algorithm, so cubes come out evenly loaded. carry_on_essentials lists what to keep with you in case checked luggage is lost or delayed. packing_glossary defines common packing terms.

What it is not

Not a live baggage-fee calculator or a visa-eligibility checker. Airline baggage allowances change by fare class, route, season and frequent-flyer status — every figure in airline_baggage_rules is the airline's standard economy allowance as verified on the date the data was built, and may not match your specific fare. Country entry requirements, visa rules and vaccination requirements are set by each destination, change without much notice, and depend heavily on your nationality — document_checklist is deliberately general, not destination-specific, and always points you back to the destination's official source. For anything time-sensitive, confirm directly with the airline or the destination's official government/embassy site before you travel.

Tools

Packing lists

generate_packing_list — A categorized packing list (clothing, toiletries, electronics, documents, health, plus activity-specific gear) for a trip type, duration and climate. Clothing quantities are scaled sensibly by duration (capped, with a laundry-assumption note for longer trips) rather than one item per day. Use for "help me pack for a 10-day hiking trip in a cold climate". Args: trip_type, duration_days, climate, activities.

packing_cube_organizer — Groups a packed-item list into num_cubes packing cubes using an LPT load-balancing algorithm (items are size-scored by category and greedily assigned to the currently-lightest cube), so cubes come out evenly loaded rather than randomly split. Use for "organize my packing list into 3 cubes". Args: items, num_cubes.

carry_on_essentials — A 'just in case checked luggage is lost or delayed' carry-on essentials list: medication, a change of clothes, chargers, valuables and documents. Use for "what should I keep in my carry-on in case my bag is lost". Args: trip_duration_days.

Airlines

airline_baggage_rules — Hand-verified checked and carry-on baggage size/weight allowances for one of 24 major airlines (North America, Europe, the Middle East, Asia, India, Brazil). Use for "what's the checked bag limit on United". Args: airline.

compare_baggage_allowance — Side-by-side checked and carry-on baggage allowances for two airlines. Use for "compare Ryanair and easyJet baggage rules". Args: airline_a, airline_b.

weight_estimator — Sums a list of packed items' estimated weights and, given an airline or an explicit limit, flags whether the total is likely to exceed the checked-bag weight limit. Use for "will my bag be overweight for Delta". Args: items, airline, checked_limit_kg.

liquids_rule_check — Checks one carry-on liquid/gel/aerosol item against the common international 3-1-1-style rule (each container ≤100ml/3.4oz, all containers fitting in one 1L/1-quart bag). Use for "can I bring a 150ml bottle of sunscreen in my carry-on". Args: item_name, volume_ml.

Reference

climate_pack_adjustments — Clothing-layer guidance for a climate and season combination (e.g. what to actually pack for a temperate destination in autumn). Use for "what should I pack for a cold climate in winter". Args: destination_climate, season.

document_checklist — A general checklist of documents commonly needed for a trip (passport, visa reminder, travel insurance, vaccination card, driver's license/IDP, booking confirmations) — generic guidance, not destination-specific visa or entry rules, which change too often and vary too much by nationality to hardcode safely. Use for "what documents do I need for an international business trip". Args: trip_type, international.

packing_glossary — Definitions of common packing terms (packing cube, compression bag, TSA lock, personal item vs carry-on, layering, the 3-1-1 liquids rule, capsule wardrobe, ...). Use for "what's a packing cube", "what does TSA lock mean". Args: term.

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.

Packlist — Privacy Policy

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

What Packlist is. Packlist is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for a fully local travel packing-list generator and airline baggage-rule reference: packing lists, airline baggage allowances, a liquids-rule checker, a weight estimator, climate guidance, a document checklist, a packing-cube organizer, carry-on essentials and a glossary. You interact with your assistant; the assistant sends us only the arguments needed for that one lookup or computation.

What we receive. The arguments of each tool call — a trip type, duration, climate, activity list, airline name, item names and weights, a liquid's volume, a climate/season pair, 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-curated reference data or computed in-process, 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. Packing-list contents, item names and weights you send us for weight_estimator or packing_cube_organizer are used only to compute that one response and are never retained.

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 reference 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. Packlist is a general-audience service operated by the adult using the assistant.

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

Packlist — Terms of Service

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

1. The Service. Packlist generates travel packing lists and returns airline baggage-rule reference information, a liquids-rule check, a weight estimate, climate guidance, a document checklist, a packing-cube organizer, carry-on essentials and a glossary — from hand-curated data and computation, entirely local to the Service. It is accessed through an AI assistant or directly over MCP or HTTP.
2. Not a live rules engine, and not official. Packlist is an independent reference and planning tool, not affiliated with or endorsed by any airline, aviation authority, or government. It does not provide live baggage-fee quotes, real-time security-checkpoint rules, or destination-specific visa or entry determinations, and nothing in the Service should be relied on as a substitute for checking with your airline or destination's official source before you travel.
3. Facts change. Airline baggage allowances vary by fare class, route, season and status, and change without notice; country entry, visa and vaccination requirements are set by each destination and depend on your nationality. Every figure and checklist reflects the build date stated in the Service's own data — always verify anything time-sensitive with the airline or the destination's official government/embassy source.
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 bundled reference data or computed on the spot, 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, including a missed flight, an overweight-bag fee, a denied boarding, or a visa or entry issue. Our total liability is limited to US $100.
9. Governing law. California law; venue in San Mateo County, California.
