# Use agentmarkup with your agent.

[agentmarkup](https://agentmarkup.dev/) (`agentmarkup.dev`) registers 10 WebMCP tools. 3 of 10 tools declares `readOnlyHint`, so an agent can invoke them through `tools.call`. The registry runs the tool in a fresh headless page on agentmarkup.dev and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/agentmarkup.dev) listing for `agentmarkup.dev`, last live-checked by the registry at 2026-09-22T23:11:07.906Z. Run `ghostget webmcp sites.get --input '{"domain":"agentmarkup.dev"}' --json` for the current schema; the listing can drift between checks.

## Use agentmarkup 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":"agentmarkup.dev"}' --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":"agentmarkup.dev","tool":"compile_agent_surface","input":"{}"}' --json
```

agentmarkup publishes 10 tools on agentmarkup.dev; 3 declare `readOnlyHint`.

| `inspect_image_c2pa` | Fetch a single image (by CSS selector or URL) and return its fully decoded C2PA manifest store: every manifest's claim, assertions (e.g. c2pa.actions edit history, schema.org authorship), and the COSE signature details (algorithm and signin | Listed for discovery; the registry allows read-only calls only |

| `scan_images_c2pa` | Scan every <img> on the current page for C2PA Content Credentials (content provenance metadata) and return a per-image summary: whether a manifest is present, the claim generator (the tool that produced or edited the image), the title, and | Listed for discovery; the registry allows read-only calls only |
| `set_access_policy` | Set crawler access by intent group or crawler name and update Content-Signal directives in the Studio draft. | 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 agentmarkup changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on agentmarkup.dev, browse the site itself or check back when the registry lists more tools.
