MCP tools · 5 exposed · ~470 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
get_plan_coverage ~70

List every country a regional or global plan covers. Takes the group_id from a plan returned by plan_trip or list_plans. Local plans have a null group_id and cover only their own country.

NameTypeReqDescription
group_idintegeryesThe plan group id, from a plan's group_id field

No output schema declared.

No examples provided.

list_plans ~110

List eSIM plans for one country, cheapest first. Use plan_trip instead when the user is visiting more than one country.

NameTypeReqDescription
countrystringyesISO country code such as JP, or a slug such as south-korea
daysintegerOnly plans lasting at least this many days
limitintegerHow many plans to return, default 20
min_data_gbnumberOnly plans with at least this much data. Unlimited plans always qualify

No output schema declared.

No examples provided.

list_popular_destinations ~65

List the destinations travellers buy eSIMs for most often, with a starting price for each. Use this only when the user has not named a destination and wants ideas. If they already named one country use list_plans, and if they named several use plan_trip.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

plan_trip ~131

Work out the cheapest way to stay connected across several countries. Compares one regional plan covering the whole trip against buying a local plan per country, and says which is cheaper. Use this whenever the user names more than one destination.

NameTypeReqDescription
countriesarrayyesTwo-letter ISO country codes, for example ["JP", "KR", "TW"]. This tool does not accept country names or slugs: call search_destinations first to get the code.
daysintegerTrip length in days
min_data_gbnumberMinimum data per plan, in GB. Unlimited plans always qualify

No output schema declared.

No examples provided.

search_destinations ~94

Find countries CheapereSIM sells eSIM plans for, by full or partial name. Use this when the user names a place and you need its country code before looking up plans. Do not use it to compare prices or list plans: use list_plans for a single country, or plan_trip for several.

NameTypeReqDescription
querystringyesCountry name or partial name, for example "jap" or "south kor"
