# Use Leonidas Tsementzis with your agent.

[Leonidas Tsementzis](https://leotsem.com/) (`leotsem.com`) registers 1 WebMCP tools. 1 of 1 tool declares `readOnlyHint`, so an agent can invoke it through `tools.call`. The registry runs the tool in a fresh headless page on leotsem.com and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/leotsem.com) listing for `leotsem.com`, last live-checked by the registry at 2026-09-21T21:42:29.457Z. Run `ghostget webmcp sites.get --input '{"domain":"leotsem.com"}' --json` for the current schema; the listing can drift between checks.

## Use Leonidas Tsementzis 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":"leotsem.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":"leotsem.com","tool":"search_publication","input":"{}"}' --json
```

## Registered WebMCP tools

Leonidas Tsementzis publishes 1 tools on leotsem.com; 1 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `search_publication` | Search Leonidas Tsementzis's public articles, talks, photographs, and background information. Matching publication details and canonical paths are returned, and a visible result panel is displayed; this never contacts anyone or changes site | 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 Leonidas Tsementzis changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on leotsem.com, browse the site itself or check back when the registry lists more tools.
