# Use iammatthias with your agent.

[iammatthias](https://iammatthias.com/) (`iammatthias.com`) registers 4 WebMCP tools. 3 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 iammatthias.com and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/iammatthias.com) listing for `iammatthias.com`, last live-checked by the registry at 2026-09-21T21:17:54.338Z. Run `ghostget webmcp sites.get --input '{"domain":"iammatthias.com"}' --json` for the current schema; the listing can drift between checks.

## Use iammatthias 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":"iammatthias.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":"iammatthias.com","tool":"list_content","input":"{}"}' --json
```

## Registered WebMCP tools

iammatthias publishes 4 tools on iammatthias.com; 3 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `list_content` | List published entries on this site, newest first, optionally filtered to one section (art, posts, recipes, melange, experiments) or one tag. | Callable read-only tool |
| `open_entry` | Navigate the browser to a specific entry on this site by its path or slug, e.g. 'posts/1779066375000-farfield'. | Listed for discovery; the registry allows read-only calls only |
| `read_current_page` | Return the markdown source of the page currently open, with front matter and images resolved to public URLs. Cheaper and cleaner than parsing the rendered DOM. | Callable read-only tool |
| `search_site` | Search this site's writing, photography notes, and recipes by keyword. Returns titles, excerpts, and both HTML and markdown URLs. | 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 iammatthias changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on iammatthias.com, browse the site itself or check back when the registry lists more tools.
