Proofstack tools (3)
write = sends, deletes, buys or postsget_caseFreeFetch 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.
pricing_benchmarksFreePricing 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.
search_casesFreeSearch 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.

ProofStack MCP Server
Remote Model Context Protocol server for ProofStack — a library of audited indie product business cases. Every figure is read from a published source (pricing pages, founder posts, transparency dashboards) and linked, so AI assistants can cite evidence instead of guessing.
Endpoint (Streamable HTTP, no auth required):
https://proof-stack-lake.vercel.app/mcpTools
Example client configuration
{
"mcpServers": {
"proofstack": {
"url": "https://proof-stack-lake.vercel.app/mcp"
}
}
}Works with any MCP client that supports remote Streamable HTTP servers (Claude Desktop / Claude Code, Cursor, etc.).
Data honesty rules
- Revenue that is not publicly disclosed is returned as unknown — never estimated.
- Acquisition narratives are researched from first-party sources; cases that have not been researched yet say so explicitly instead of returning template text.
- Every case ships its evidence: source URLs with evidence grades (A/B/C).
Open dataset: the full case library and benchmarks are downloadable at proofstack-dataset (CC BY 4.0).
