# fetch

Get full detail on one published listing by its listing slug (not a contributor slug). Read-only, no authentication required (public endpoint, IP rate-limited). Returns title, description, short_description, product_story, included_components, use_cases, industry_focus, complexity_level, listing_type, product_formats, thumbnail_url, an array of pricing tiers (name, price_cents, setup_fee_cents, description, billing_interval, features), a contributor object (slug, display_name, badge_tier, bio, credential_summary, credential_badges), and a category object (name, slug). Use after search or list_categories to drill into a specific result.

## Parameters

| Parameter | Type | Required | Description |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "fetch",
    "arguments": {
      "slug": "<slug>"
    }
  }
}
```

## Why fetch is rated Low

This is a straightforward data retrieval operation with no side effects. It queries and returns public marketplace listing information without modifying, executing, or deleting any data. The read-only designation and public endpoint access confirm no mutation or execution risk.

From the tool's own definition: "Tool description explicitly states 'Read-only, no authentication required (public endpoint, IP rate-limited)'. Function retrieves full details of published marketplace listings by slug."

## Use case

AI agents call fetch to retrieve information from Marketplace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Marketplace:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "fetch": {}
  }
}
```
