What this MCP does

Searches audited software business cases and provides source-backed pricing, revenue, and paywall benchmarks.

Capabilities

Tools

3 tools
get_case
Fetch one audited case by slug: pricing tiers as published, the paid trigger, what to copy, what NOT to copy, and every evidence source with its URL and grade.
Input schema 
{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': "The case slug, e.g. 'tally-forms' (find slugs via search_cases)."}}}
pricing_benchmarks
Pricing statistics counted from the published pricing pages of audited cases: median first paid tier, free-tier prevalence, and which capabilities most often sit behind the paywall. Products without a public price are excluded rather than estimated; no ranking or traffic figures exist here because those cannot be verified freely.
Input schema 
{'type': 'object', 'properties': {'category': {'type': 'string', 'description': "Optional category, e.g. 'Micro SaaS'. Omit for the whole library."}}}
search_cases
Search ProofStack's audited business-model case studies of small software products. Every case carries revenue and pricing claims linked to public sources with an evidence grade, plus an explicit list of what does NOT transfer to other builders.
Input schema 
{'type': 'object', 'required': ['query'], 'properties': {'query': {'type': 'string', 'description': "Keywords: a product name, category, or business question (e.g. 'form builder', 'open source analytics')."}, 'category': {'type': 'string', 'description': "Optional exact category filter, e.g. 'Micro SaaS', 'Developer Tools', 'AI Tools'."}}}
