# Use Lago with your agent.

[Lago](https://getlago.com/) (`getlago.com`) registers 6 WebMCP tools. 4 of 6 tools declares `readOnlyHint`, so an agent can invoke them through `tools.call`. The registry runs the tool in a fresh headless page on getlago.com and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/getlago.com) listing for `getlago.com`, last live-checked by the registry at 2026-09-23T00:52:04.762Z. Run `ghostget webmcp sites.get --input '{"domain":"getlago.com"}' --json` for the current schema; the listing can drift between checks.

## Use Lago 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":"getlago.com"}' --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":"getlago.com","tool":"get_site_overview","input":"{}"}' --json
```

## Registered WebMCP tools

Lago publishes 6 tools on getlago.com; 4 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `get_site_overview` | Get an outline of the Lago documentation, grouped by section, with a short description of each page. May be truncated for large sites; use search_docs to find pages not listed. | Callable read-only tool |
| `navigate_page` | Navigate the current browser tab to a Lago documentation page. | Listed for discovery; the registry allows read-only calls only |
| `read_page` | Read the full content of a Lago documentation page as markdown. | Callable read-only tool |
| `read_skill` | Read a Lago agent skill document by name. | Callable read-only tool |
| `search_docs` | Search the Lago documentation for relevant pages and content. | Callable read-only tool |
| `search_lago_documentation` | Find authoritative Lago documentation for an API, billing workflow, integration, or deployment task. This read-only tool returns canonical documentation links and summaries. | 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 Lago changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on getlago.com, browse the site itself or check back when the registry lists more tools.
