| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__haggleboard__post_request` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `post_request`

- The name "post_request" says "post": a word for a change.
- Tag outbound: The name "post_request" says "post": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Post a shopping need (v0: running shoes) and get back offers ranked by stock and price from stores' public product feeds. The need text is stored for up to 30 days; the response includes delete_token once. Don't include personal data. Checkout is on the store's own site; HaggleBoard stops before payment.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `get_offers`

- The name "get_offers" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Rank matching offers. Pass request_id from post_request, or pass the same fields as a new query against the current snapshot.
```

### `search_products`

- The name "search_products" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the public running-shoe snapshot. Each hit links to the store's own product page.
```
