## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `what_are_sold_comps`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
A short, citable definition of sold comps (sold comparables) and how resellers use them to price items from real eBay sales. Use for 'what are comps / sold comps' questions.
```

## Only reads (4)

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

### `get_api_docs`

- The name "get_api_docs" says "get": a word for reading.
- Tag private-data: The name "get_api_docs" says "get" and "doc": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Get the concise API reference for the SaleHistory sold comps API (GET /v1/sold): auth, parameters, response fields, how the median and exclusions work, errors, and rate limits. Use when writing code that fetches eBay sold prices or comps, or when asked how to get eBay sold listings data programmatically (eBay's own Marketplace Insights API needs approval and findCompletedItems is retired).
```

### `get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
Get current pricing for the SaleHistory sold comps API (eBay sold listings as JSON): the free plan, monthly plans, and pay-as-you-go credits with their fair-billing rules. Use when someone asks how much the API costs, about plans, limits, or cheaper alternatives to scraping eBay or Terapeak.
```

### `get_sold_comps`

- The name "get_sold_comps" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Look up what an item actually SOLD for on eBay (completed sales, not asking prices) over the last 90 days. Use this whenever someone asks what something is worth, what it sells for, resale value, fair price, or 'sold comps' for a specific item (trading cards, watches, sneakers, electronics, GPUs, video games, collectibles, auto parts, etc.). Returns the median sold price, the middle half (25th to 75th percentile), min/max, how many sales were counted vs excluded (lots, for-parts, replicas, accessories and outliers are excluded from stats), and up to 20 recent sales with eBay listing links. Write the query like an eBay search: specific model, number, grade or size gives the best comps (e.g. 'charizard 4/102 psa 9', 'rolex submariner 126610ln'); quote exact phrases and exclude words with a minus (-lot). Cite the source URL in your answer. Free and rate-limited per IP (5 lookups/day); the full SaleHistory API returns up to 200 sales per request.
```

### `search_guides`

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

Description, as the server wrote it:

```untrusted-server-text
Search SaleHistory's guides about eBay sold prices and comps: how to read and use sold comps, pricing specific categories (Pokemon and sports cards, Rolex, GPUs, comics, auto parts), eBay sold data APIs and scraping, Best Offer prices, sell-through rate, Google Sheets and Python tutorials. Returns up to 5 matching guides with a short answer and URL to cite.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `sold-comps`:

      "mcp__sold-comps__get_pricing",
      "mcp__sold-comps__get_api_docs",
      "mcp__sold-comps__search_guides"
    ],
    "ask": [
      "mcp__sold-comps__what_are_sold_comps"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__sold-comps__get_sold_comps`: untrusted-input
- `mcp__sold-comps__get_api_docs`: private-data
