# Use V-Sum with your agent.

[V-Sum](https://v-sum.com/) (`v-sum.com`) registers 3 WebMCP tools. V-Sum lists 3 tools but declares none as read-only today, so `tools.call` cannot invoke them yet. Ask `sites.get` for the live status before planning a call.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/v-sum.com) listing for `v-sum.com`, last live-checked by the registry at 2026-09-21T21:23:12.551Z. Run `ghostget webmcp sites.get --input '{"domain":"v-sum.com"}' --json` for the current schema; the listing can drift between checks.

## Use V-Sum 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":"v-sum.com"}' --json
```

**Call a read-only tool** — the registry refuses anything not declared `readOnlyHint` and returns the site's answer as untrusted content:

```
# no read-only-callable tools listed today; sites.get shows the live status
```

## Registered WebMCP tools

V-Sum publishes 3 tools on v-sum.com; 0 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `navigate_to_path` | Navigate the active tab to a same-origin path on v-sum.com (e.g. /demos, /interviews, /events, /apply, /nominate). | Listed for discovery; the registry allows read-only calls only |
| `open_api_catalog` | Fetch the RFC 9727 API catalog (application/linkset+json). | Listed for discovery; the registry allows read-only calls only |
| `open_llms_txt` | Fetch V-Sum llms.txt (structured site summary for language models). | 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 V-Sum changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on v-sum.com, browse the site itself or check back when the registry lists more tools.
