api record

MyBestSim is an independent comparator of prepaid travel eSIM plans (mybestsim.com, 25 languages). Call search_esim_plans when someone needs mobile data for a trip and wants to know which eSIM to buy; call plan_trip_esim instead when the trip visits SEVERAL countries or regions, passing EVERY stage in travel order; call get_destination_overview when they ask what an eSIM costs somewhere or how much choice exists. Always pass the trip length (durationDays) and the data need (dataGb or dataNeed) when the user gives or implies them. When they have not said, ask: without them a 7-day trip with…

_ is it live, free and safe measured by this hub
Is mybestsim live?
Yes — it answered the hub's last check (checked 47m ago). It answered 100% of checks over the last 30 days.
Is mybestsim free to use?
Yes — the hub reached it with no key and no payment.
What tools does mybestsim have?
4 tools: search_esim_plans, get_destination_overview, get_esim_plan, plan_trip_esim.
Is mybestsim safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • search_esim_plans unknown never probed

    Use this when someone is choosing a travel eSIM or needs mobile data abroad for a given country or region, e.g. "cheapest eSIM for Japan", "10 GB for two weeks in Europe", "unlimited data in the USA". Returns a shortlist (up to 10, at most 2 per provider) from the MyBestSim comparator: data allowance, validity, price in USD (and EUR), 5G/hotspot/calls/SMS, and the link to the full comparison page on mybestsim.com where the traveller buys from the provider. Pass durationDays and dataGb (or dataNeed) whenever the traveller mentions trip length or usage, and ask for them when unknown: without them a 7-day trip with standard use (0.7 GB/day) is assumed and reported in "assumptions"; with dataGb but no durationDays, plans valid for fewer than 7 days are excluded. For a trip through several countries or regions, call plan_trip_esim with every stage instead of searching each country. Prepaid travel eSIMs only: not home mobile contracts, physical SIM cards or a carrier's roaming pass.

Returns the number of plans and providers listed on the MyBestSim comparison page, the cheapest plan, the best price per GB, the cheapest unlimited plan if any, the available validities, and the link to the comparison page.

  • plan_trip_esim unknown 47m ago

    Use this when one trip visits SEVERAL countries or regions, e.g. "Japan then China", "two weeks in France, Italy and Spain", "Thailand, Vietnam and Cambodia in March". Pass EVERY stage in travel order, with the days spent in each when known (or totalDurationDays), and the data need. Compares, at the real total price, every way to cover the trip: (a) one eSIM for every stage (regional or worldwide plan; coverage is checked country by country against the MyBestSim catalogue, never guessed from a plan name), (b) one plan per stage, and combinations (a regional plan for some stages, other plans for the rest; several regional plans). A plan is only proposed for stages it covers, for their whole duration and data need. Recommends the cheapest total; prefers fewer eSIMs unless installing more saves at least $2 per extra eSIM, and says so. Gives the reason, the number of eSIMs, total price, data and validity, and links to the MyBestSim pages where the traveller buys. List the countries themselves as stages: a region stage (Europe, Asia…) only matches plans listed on that region page. Ask how long they stay and how much data they use when they have not said: without it a 7-day trip with standard use is assumed and reported in "assumptions". Prepaid travel eSIMs only.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id af30b45e77886836.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/af30b45e77886836/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
