# get_contributor_profile

Get a contributor's public profile and their published listings, by contributor slug (not a listing slug). Read-only, no authentication required (public endpoint, IP rate-limited). Returns display_name, bio, credential_summary, positioning_statement, badge_tier, avg_rating, review_count, pull_quote, social/website URLs, credential_badges, published_listing_count, and a listings array (slug, title, price_cents) for that contributor. Use to learn more about who built a listing returned by search or fetch -- not for looking up a listing directly.

## Why get_contributor_profile is rated Low

This tool retrieves public profile information about marketplace contributors without modifying any data. The read-only nature, lack of authentication requirement, and public endpoint designation confirm it has no side effects. The rate-limiting provides standard abuse protection.

From the tool's own definition: "Tool description explicitly states 'Read-only, no authentication required (public endpoint, IP rate-limited)' and returns only profile metadata and published listing summaries without side effects."

## Use case

AI agents call get_contributor_profile 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": {
    "get_contributor_profile": {}
  }
}
