- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (131 of 135), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (131 of 135), so this covers what we could see, not the whole tree.

  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 607 tokens (~202/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.

## MCP tools (3)

### `extract_newsletter_products` (~217 tokens)

Extract affiliate links, product recommendations, and sponsored mentions from newsletter content. Pass the newsletter body directly as HTML or plain text — does not fetch content from URLs. Supports Substack, Ghost, and Beehiiv HTML plus plain text. Returns product name, category, affiliate link URL, recommendation strength, and sponsor flag. Call this before analyze_newsletter_sponsors or track_product_trends — both tools reuse its cache. Use for monetization analysis, affiliate auditing, and cross-issue tracking. Example: newsletter_id='morning-brew-2026-03-12', category_filter=['saas','physical_goods'].

Input parameters:

- `api_key` (string): Optional API key for paid access beyond the free tier
- `category_filter` (array): Optional list of categories to include: saas, physical_goods, course, supplement, book, service, media, other
- `content` (string, required): Newsletter content as HTML or plain text
- `newsletter_id` (string): Optional newsletter issue identifier for caching and trend tracking

### `analyze_newsletter_sponsors` (~221 tokens)

Identify sponsored sections in a newsletter and estimate advertising value: CPM, read-through rate, and sponsor-reader fit score. Returns each sponsor's name, placement type (dedicated section, inline, footer), estimated CPM based on industry benchmarks, and audience fit score. Revenue estimates are benchmark averages — not live ad-platform data. Use for advertising intelligence, sponsor acquisition research, and ad placement optimization. Use this tool for sponsor metrics only; for the full affiliate product and link list use extract_newsletter_products instead. Reuses cached extraction when newsletter_id matches a prior extract_newsletter_products call. Example: newsletter_id='tldr-2026-03-12' → returns [{sponsor:'Warp', placement:'dedicated_section', estimated_cpm:40, fit_score:0.85}].

Input parameters:

- `api_key` (string): Optional API key for paid access beyond the free tier
- `content` (string, required): Newsletter content as HTML or plain text
- `newsletter_id` (string): Optional newsletter issue identifier — uses cached extraction if available

### `track_product_trends` (~169 tokens)

Compare affiliate product mentions and brand frequency across multiple newsletter issues to detect rising, stable, and declining trends. Returns trend velocity, mention count per issue, and category breakdown. No AI call — computed from cached extraction data only. Use for affiliate marketing optimization, editorial product tracking, and sponsor category analysis. Requires prior extract_newsletter_products call for each newsletter_id — returns an error listing missing IDs if any are not in cache. Example: newsletter_ids=['issue-101','issue-102'].

Input parameters:

- `api_key` (string): Optional API key for paid access beyond the free tier
- `category_filter` (array): Optional category filter to narrow trend analysis
- `newsletter_ids` (array, required): List of newsletter issue IDs to analyze. Each must have been previously extracted via extract_newsletter_products.
