# Use ngrok.com with your agent.

[ngrok.com](https://ngrok.com/) (`ngrok.com`) registers 11 WebMCP tools. 9 of 11 tools declares `readOnlyHint`, so an agent can invoke them through `tools.call`. The registry runs the tool in a fresh headless page on ngrok.com and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/ngrok.com) listing for `ngrok.com`, last live-checked by the registry at 2026-09-23T06:11:50.653Z. Run `ghostget webmcp sites.get --input '{"domain":"ngrok.com"}' --json` for the current schema; the listing can drift between checks.

## Use ngrok.com 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":"ngrok.com"}' --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":"ngrok.com","tool":"get_agent_setup_prompt","input":"{}"}' --json
```

## 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 ngrok.com changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on ngrok.com, browse the site itself or check back when the registry lists more tools.
