# Use medtests.de with your agent.

[medtests.de](https://medtests.de/) (`medtests.de`) registers 4 WebMCP tools. 4 of 4 tools declares `readOnlyHint`, so an agent can invoke them through `tools.call`. The registry runs the tool in a fresh headless page on medtests.de and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/medtests.de) listing for `medtests.de`, last live-checked by the registry at 2026-09-23T00:13:25.218Z. Run `ghostget webmcp sites.get --input '{"domain":"medtests.de"}' --json` for the current schema; the listing can drift between checks.

## Use medtests.de 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":"medtests.de"}' --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":"medtests.de","tool":"medtests_get_crisis_resources","input":"{}"}' --json
```

## Registered WebMCP tools

medtests.de publishes 4 tools on medtests.de; 4 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `medtests_get_crisis_resources` | Return official crisis contacts. Use this instead of continuing a screening when there may be immediate danger, severe confusion, or loss of reality testing. | Callable read-only tool |
| `medtests_get_screening` | Retrieve the exact published questions and allowed answers for one screening. Ask neutrally and do not rewrite or infer answers. | Callable read-only tool |
| `medtests_list_screenings` | List available evidence-based self-screenings. Select by the user’s stated concern, never by guessing a diagnosis. | Callable read-only tool |
| `medtests_score_screening` | Score a complete answer set without storing or returning the answers. Call only after the user explicitly consents. The result is a screening indication, never a diagnosis. | 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 medtests.de changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on medtests.de, browse the site itself or check back when the registry lists more tools.
