# Use Bonjour RATP with your agent.

[Bonjour RATP](https://bonjour-ratp.fr/) (`bonjour-ratp.fr`) registers 1 WebMCP tools. Bonjour RATP lists 1 tool but declares none as read-only today, so `tools.call` cannot invoke them yet. Ask `sites.get` for the live status before planning a call.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/bonjour-ratp.fr) listing for `bonjour-ratp.fr`, last live-checked by the registry at 2026-09-22T18:14:26.501Z. Run `ghostget webmcp sites.get --input '{"domain":"bonjour-ratp.fr"}' --json` for the current schema; the listing can drift between checks.

## Use Bonjour RATP 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":"bonjour-ratp.fr"}' --json
```

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

```
# no read-only-callable tools listed today; sites.get shows the live status
```

## Registered WebMCP tools

Bonjour RATP publishes 1 tools on bonjour-ratp.fr; 0 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `build_bonjour_ratp_itinerary_url` | Generates a deep-link URL to Bonjour RATP for transit routes, itineraries, and directions in Paris / Île-de-France (IDF). USE WHEN user asks in English or French for: "itinerary", "route", "directions", "how to go to", "itinéraire", "trajet | Listed for discovery; the registry allows read-only calls only |

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