# Use topograph.co with your agent.

[topograph.co](https://topograph.co/) (`topograph.co`) registers 2 WebMCP tools. 1 of 2 tools declares `readOnlyHint`, so an agent can invoke it through `tools.call`. The registry runs the tool in a fresh headless page on topograph.co and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/topograph.co) listing for `topograph.co`, last live-checked by the registry at 2026-09-21T21:15:36.630Z. Run `ghostget webmcp sites.get --input '{"domain":"topograph.co"}' --json` for the current schema; the listing can drift between checks.

## Use topograph.co 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":"topograph.co"}' --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":"topograph.co","tool":"search_companies","input":"{}"}' --json
```

## Registered WebMCP tools

topograph.co publishes 2 tools on topograph.co; 1 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `book_demo` | Open the Topograph contact/demo modal. Use when the user wants to talk to sales or request API access. | Listed for discovery; the registry allows read-only calls only |
| `search_companies` | Search the Topograph company directory by legal name or registration number. Navigates the current page to the filtered results. | 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 topograph.co changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on topograph.co, browse the site itself or check back when the registry lists more tools.
