# Use E-Worker with your agent.

[E-Worker](https://eworker.ca/) (`eworker.ca`) 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 eworker.ca and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/eworker.ca) listing for `eworker.ca`, last live-checked by the registry at 2026-09-22T23:13:17.831Z. Run `ghostget webmcp sites.get --input '{"domain":"eworker.ca"}' --json` for the current schema; the listing can drift between checks.

## Use E-Worker 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":"eworker.ca"}' --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":"eworker.ca","tool":"eworker_list_apps","input":"{}"}' --json
```

## Registered WebMCP tools

E-Worker publishes 4 tools on eworker.ca; 3 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `eworker_list_apps` | List the available E-Worker 8 apps with stable IDs, summaries, and same-origin routes. | Callable read-only tool |
| `eworker_open_app` | Navigate this browser tab to an available app returned by eworker_list_apps. This does not edit or save content. The destination app controls its own features and permissions. | Listed for discovery; the registry allows read-only calls only |
| `eworker_resolve_app` | Resolve one exact app ID from eworker_list_apps to its approved same-origin route and URL without navigating. | Callable read-only tool |
| `eworker_site_status` | Read the public E-Worker identity, root route, available root WebMCP capabilities, and public app count. | 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 E-Worker changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on eworker.ca, browse the site itself or check back when the registry lists more tools.
