# Use neohack with your agent.

[neohack](https://neohack.dev/) (`neohack.dev`) registers 11 WebMCP tools. 4 of 11 tools declares `readOnlyHint`, so an agent can invoke them through `tools.call`. The registry runs the tool in a fresh headless page on neohack.dev and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/neohack.dev) listing for `neohack.dev`, last live-checked by the registry at 2026-09-23T01:14:32.188Z. Run `ghostget webmcp sites.get --input '{"domain":"neohack.dev"}' --json` for the current schema; the listing can drift between checks.

## Use neohack 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":"neohack.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":"neohack.dev","tool":"help","input":"{}"}' --json
```

## Registered WebMCP tools

neohack publishes 11 tools on neohack.dev; 4 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `equipment` | Explicitly wield, wear, remove, quiver, swap or toggle twoWeapon. Item discovery through use supplies equipment offers. | Listed for discovery; the registry allows read-only calls only |
| `help` | List agent families or read one complete variant schema. | Callable read-only tool |
| `interact` | Without action, discover perceived square attempts for free (default self). With action, explicitly attack, open, close, kick, chat, loot, pay, pray, enhance, search or rest. | Listed for discovery; the registry allows read-only calls only |
| `inventory` | Explicitly pickup, drop or configurePickup. Item discovery through use supplies inventory offers. | Listed for discovery; the registry allows read-only calls only |
| `lookup` | Read the pinned game encyclopedia by name. | Callable read-only tool |
| `observe` | Read current state and verify uncertain input for free. With operationId, read an exact historical receipt under result instead. | Callable read-only tool |
| `plan` | Read perceived frontiers or a route without moving. action: frontiers or route. | Callable read-only tool |
| `respond` | Answer or cancel the exact decisionId. action answer requires value matching decision.reply.valueSchema; cancellation must be permitted. | Listed for discovery; the registry allows read-only calls only |
| `session` | Create, resume, suspend or explicitly quit a run. action is required; quit retains the engine confirmation. | Listed for discovery; the registry allows read-only calls only |
| `travel` | Explicit mode: step, run, climb, to, explore or descend. One step retains ordinary semantics; navigation legs are bounded. runMode selects native run behavior. | Listed for discovery; the registry allows read-only calls only |
| `use` | Without action, discover perceived item actions for free. With explicit action, attempt item use, firing, casting or engraving. Never infer an operation; real engine decisions stay explicit. | 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 neohack changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on neohack.dev, browse the site itself or check back when the registry lists more tools.
