  "markdown": "# ProofStack MCP Server\n\nRemote [Model Context Protocol](https://modelcontextprotocol.io) server for [ProofStack](https://proof-stack-lake.vercel.app) — 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.\n\n**Endpoint** (Streamable HTTP, no auth required):\n\n```\nhttps://proof-stack-lake.vercel.app/mcp\n```\n\n## Tools\n\n| Tool | What it does |\n|---|---|\n| `search_cases` | Search 43 audited products by keyword, category, business model, or acquisition channel |\n| `get_case` | Full case detail: pricing tiers, revenue disclosures, acquisition operations, what to copy / what not to copy, and source URLs for every claim |\n| `pricing_benchmarks` | Median first paid tier, free-tier prevalence, and paywall-capability distribution, computed from published pricing pages |\n\n## Example client configuration\n\n```json\n{\n  \"mcpServers\": {\n    \"proofstack\": {\n      \"url\": \"https://proof-stack-lake.vercel.app/mcp\"\n    }\n  }\n}\n```\n\nWorks with any MCP client that supports remote Streamable HTTP servers (Claude Desktop / Claude Code, Cursor, etc.).\n\n## Data honesty rules\n\n- Revenue that is not publicly disclosed is returned as `unknown` — never estimated.\n- Acquisition narratives are researched from first-party sources; cases that have not been researched yet say so explicitly instead of returning template text.\n- Every case ships its evidence: source URLs with evidence grades (A/B/C).\n\n**Open dataset**: the full case library and benchmarks are downloadable at [proofstack-dataset](https://github.com/lttxzmj/proofstack-dataset) (CC BY 4.0).\n\nMore machine-readable context: [llms.txt](https://proof-stack-lake.vercel.app/llms.txt) · [Pricing benchmarks](https://proof-stack-lake.vercel.app/benchmarks) · [Case library](https://proof-stack-lake.vercel.app/cases)\n",
