# Use NegativeEV with your agent.

[NegativeEV](https://negativeev.com/) (`negativeev.com`) registers 1 WebMCP tools. NegativeEV lists 1 tool 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/negativeev.com) listing for `negativeev.com`, last live-checked by the registry at 2026-09-21T20:55:55.636Z. Run `ghostget webmcp sites.get --input '{"domain":"negativeev.com"}' --json` for the current schema; the listing can drift between checks.

## Use NegativeEV 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":"negativeev.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

NegativeEV publishes 1 tools on negativeev.com; 0 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `check_bet` | Check one sports bet against thousands of play-by-play simulations of the game it is on. Reads the simulations and returns the simulated win probability, the probability the quoted price implies, and the expected value at that price. Places | 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 NegativeEV changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on negativeev.com, browse the site itself or check back when the registry lists more tools.
