# Use Tax Sale Atlas with your agent.

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

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/taxsaleatlas.com) listing for `taxsaleatlas.com`, last live-checked by the registry at 2026-09-23T01:31:48.931Z. Run `ghostget webmcp sites.get --input '{"domain":"taxsaleatlas.com"}' --json` for the current schema; the listing can drift between checks.

## Use Tax Sale Atlas 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":"taxsaleatlas.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":"taxsaleatlas.com","tool":"estimate_max_bid","input":"{}"}' --json
```

## Registered WebMCP tools

Tax Sale Atlas publishes 2 tools on taxsaleatlas.com; 2 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `estimate_max_bid` | Show a tax-deed bid scenario, its cost deductions and editorial confidence factor in the calculator. Amounts are USD. Supply every cost assumption, including explicit zeros. The result is a planning estimate with unmodeled fees identified, | Callable read-only tool |
| `search_site` | Search public county, state, guide, glossary and calculator pages. Opens site search and displays up to 10 matching links per page. Optional state restricts county/state pages to that state. Blank query shows featured states/guides when unf | 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 Tax Sale Atlas changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on taxsaleatlas.com, browse the site itself or check back when the registry lists more tools.
