esimdata MCP

An official MCP server by esimdata that allows AI agents to search, compare, and check travel eSIM plans from multiple providers. It provides tools for finding plans by destination, retrieving detailed plan information, comparing multiple plans, getting country overviews, checking device eSIM compatibility, and listing providers. The server is read-only, free, and requires no authentication key.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

esimdata is a neutral travel eSIM comparison. Plans come from each provider's own public catalogue and are ranked only by the numbers (price, price per GB, validity) — never by commission. Every price carries the time it was checked; quote it. Give the traveller the buy_url: it opens the provider's own page, where they buy. A field that is null means the provider doesn't state it — say "not stated", never guess. esimdata sells nothing itself.

search_plans — Search travel eSIM plans

Advertised by the server during the last successful anonymous check.

Advertised read-only

Find travel eSIM data plans for a destination from every provider esimdata tracks, ranked neutrally by price (or price per GB, or validity). Filter by trip length, data, unlimited, needs (hotspot, 5G, phone number, top-up, no ID check) and budget. Each result has a buy_url to the provider's page and the time the price was checked.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
