Also use it in ChatGPT or Claude
esimgomobile is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
- 3
Create the connector
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
- 4
Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

Tools · 36
run_speed_testUse when the user wants to measure their current internet speed. Runs a real download/ping measurement in the interactive widget and reports Mbps, ping, and a quality grade.get_public_ipUse when the user asks for their public IP address. Returns the IP address the request arrives from, as seen by the server edge.check_roaming_statusUse when the user wants to know whether they are currently roaming. Compares their home country against the country they are in now.measure_latencyUse when the user wants the network latency to a host. Performs a real HTTPS HEAD request from the deployment edge and reports round-trip time to first byte in milliseconds.grade_connection_qualityUse when the user gives you download/upload speed and ping numbers and wants a verdict. Grades the connection Excellent/Good/Fair/Poor with practical advice.detect_captive_portalUse when the user is on hotel/airport/cafe Wi-Fi and suspects a login page is blocking them. Gives a step-by-step guided check — no automatic probing.check_dns_leaksUse when the user wants to check whether their DNS queries leak outside their VPN. Gives a guided manual check — browsers cannot run automatic DNS probes.get_wifi_security_checklistUse when the user is about to use public, hotel, or airport Wi-Fi. Returns a practical safety checklist.lookup_speed_requirementsUse when the user asks how much bandwidth an activity needs (video calls, 4K streaming, gaming).

Answers from esimgomobile's own published plan catalog (live-checked) plus the built-in country network reference.estimate_data_usageUse when the user is planning a trip and asks how much mobile data they need. Estimates from trip days, daily hours online, and a light/moderate/heavy usage profile, then suggests a plan size.calculate_roaming_costUse when the user wants to compare their home carrier's roaming fees against a travel eSIM. Compares a user-supplied carrier day-pass rate with an illustrative travel-eSIM daily rate.plan_multi_country_esimUse when the user has a multi-country itinerary and asks which eSIM plan type fits. Recommends single-country vs regional vs global plans from the country list.check_device_compatibilityUse when the user asks whether their phone supports eSIM.

Formats a local phone number for calling between two countries, using a built-in dialing-code table.calculate_data_budgetUse when the user asks how much of their plan data is left or how to ration it over a trip. Computes remaining data, daily budget and end-of-trip projection from the plan size and usage so far (which the user's phone reports exactly).list_available_plansUse when the user asks what esimgomobile plans exist or what an eSIM costs. Lists the real, currently published plan catalog with USD prices (live-checked against esimgomobile.com).recommend_planUse when the user says where they're going, for how long, and roughly how much they'll use data, and wants a concrete plan pick. Estimates the GB need, then picks the cheapest matching plan from the real published catalog with prices.get_travel_data_checklistUse when the user is preparing a trip and wants one pass over everything data-related for a country: networks, eSIM support, internet freedom, device check and install steps. Composes the built-in country, freedom, device and install references.search_plansUse when the user wants to browse or filter esimgomobile plans - by type (data packs, monthly, day passes), max price, minimum GB, coverage scope, or cheapest per-GB. Reads the live published catalog (snapshot fallback, labeled).get_plan_detailsUse when the user asks about one specific esimgomobile plan by id - price, data allowance, validity, coverage scope, per-GB unit price, and where to buy.compare_plansUse when the user is choosing between 2-4 esimgomobile plans. Side-by-side price, data, validity, scope and per-GB unit price, with a best-value pick. No competitor API offers this.validate_order_draftUse when the user is about to buy and wants everything checked first - the eSIM Go validate-style dry run. Verifies the plan id exists, quantity (1-50), device eSIM compatibility, and single-country scope against the itinerary, then gives a published-price estimate. Places no ordplan_tripUse when the user gives an itinerary (countries + days + usage) and wants the full answer in one call: estimated data need, best published plan pick with an alternative, and a per-country networks/eSIM/freedom brief. Composite over the live catalog and built-in country referenceslist_country_networksUse when the user asks which mobile networks operate in a country, or for eSIM support / Wi-Fi / internet-freedom facts for one country - the eSIM Go /networks parity endpoint, from esimgomobile's built-in reference.Recent checks
