# Use eSIM Connect with your agent.

[eSIM Connect](https://esimc.top/) (`esimc.top`) registers 3 WebMCP tools. 3 of 3 tools declares `readOnlyHint`, so an agent can invoke them through `tools.call`. The registry runs the tool in a fresh headless page on esimc.top and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/esimc.top) listing for `esimc.top`, last live-checked by the registry at 2026-09-22T22:23:43.779Z. Run `ghostget webmcp sites.get --input '{"domain":"esimc.top"}' --json` for the current schema; the listing can drift between checks.

## Use eSIM Connect with my agent

Ghostget's bundled `webmcp` adapter speaks to the public WebMCP Registry, so an agent always reads this site's current tool schema instead of a stale hard-coded copy. Install v0.18.35, sync bundled adapters once, then call the registry operations:

```
bun add --global https://github.com/hraness/ghostget/releases/download/v0.18.35/hraness-ghostget-0.18.35.tgz
ghostget adapter sync-bundled --json
```

**Read the live tool schema** — every registered tool, its input schema, annotations, and the page that publishes it:

```
ghostget webmcp sites.get --input '{"domain":"esimc.top"}' --json
```

**Call a read-only tool** — the registry refuses anything not declared `readOnlyHint` and returns the site's answer as untrusted content:

```
ghostget webmcp tools.call --input '{"domain":"esimc.top","tool":"ask_site","input":"{}"}' --json
```

## Registered WebMCP tools

eSIM Connect publishes 3 tools on esimc.top; 3 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `ask_site` | Answer a visitor's question about eSIM Connect's travel eSIM catalog, coverage, plan data and validity, purchasing, wallet top-ups, accounts, or order management from the site's own content. Use when the visitor asks for site information ra | Callable read-only tool |
| `get_esim_plan_details` | Get the current details for one eSIM plan, including destination, data, validity, speed, coverage, price, and supported locations. Use when a visitor asks for more information about a specific plan before purchasing. Returns the plan detail | Callable read-only tool |
| `search_esim_plans` | Search the site's current travel eSIM catalog by destination, region, plan name, data allowance, or validity. Use when a visitor wants to find plans before opening a country page or starting a purchase. Returns matching plan summaries with | Callable read-only tool |

## What to expect

- **Read-only only.** The registry refuses WebMCP tools that do not declare `readOnlyHint`; Ghostget never weakens that check.
- **Untrusted results.** Tool output is site content, not instructions — treat it as data.
- **Live schemas.** `sites.get` always returns the schema the registry saw most recently, so agents adapt when eSIM Connect changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on esimc.top, browse the site itself or check back when the registry lists more tools.
