Descriptive, never advisory.\n\n```\nhttps://mcp.crashtestyourstrategy.ai/mcp\n```\n\n[![smithery badge](https://smithery.ai/badge/nobbefrederic/crashtestyourstrategy)](https://smithery.ai/servers/nobbefrederic/crashtestyourstrategy)\n\nListed in the [official MCP registry](https://registry.modelcontextprotocol.io) as\n`io.github.fnobbe/crashtestyourstrategy`. This repository is the public server card —\nthe service itself is closed-source; everything an agent (or a reviewer) needs to\nverify behaviour is linked below.\n\n## Quick start\n\nClaude Code:\n\n```bash\nclaude mcp add --transport http ctys https://mcp.crashtestyourstrategy.ai/mcp\n```\n\nGeneric MCP client config (streamable HTTP):\n\n```json\n{\n  \"mcpServers\": {\n    \"ctys\": {\n      \"type\": \"streamable-http\",\n      \"url\": \"https://mcp.crashtestyourstrategy.ai/mcp\"\n    }\n  }\n}\n```\n\nclaude.ai: *Settings → Connectors → Add custom connector* with the URL above.\n\nThe free tier is rate-limited per IP (30 req/min). No account, no key.\n\n## What it does\n\nAn open diagnostics layer that confronts a proposed portfolio or trading strategy\nwith the failure modes an optimistic backtest ignores — hedge breaks (the 2022\nstock-bond case), sequence-of-returns risk, regime blind spots, deflated Sharpe.\n\n**Free tier (16 tools)**\n\n| Group | Tools |\n|---|---|\n| Portfolio | `portfolio_stress_test` (multi-asset stress across baseline / risk-off / rate-shock regimes, hedge-break detection, full drawdown distribution) · `portfolio_compare` · `factor_decomposition` · `ips_gate` (hard gate vs an Investment Policy Statement, breach probability not median path) · `long_horizon_stress` (multi-year savings/withdrawal plans, ruin probabilities) |\n| Strategy | `run_stress_test` · `challenge_strategy` · `backtest_integrity` (deflated Sharpe + which crisis regimes the backtest window missed) |\n| Regimes | `regime_outlook` (model-conditional BULL/SIDEWAYS/BEAR/CRISIS probabilities at 5/21 trading days — preregistered, out-of-sample validated, refreshed daily) · `market_regime_map` (18-category cross-asset map) · `describe_regime` · `find_similar_regime` |\n| Record & catalog | `list_investment_theses` · `get_investment_thesis` · `get_dossier` (citable audit trail of prior calls) · `submit_feedback` |\n\n**Full tier** (token via [contact](https://crashtestyourstrategy.com/contact)):\n`tier2_stress_test` (stress **any** ticker with auto-calibration + realism gate),\n`build_portfolio`, `portfolio_frontier`.\n\n## Response contract\n\nEvery response is a versioned envelope (`ctys-agent-v1` family) carrying:\n\n- `grounding_summary` — a risk-focused factual statement of the omitted tail\n- `revision_required` — a gate-capable signal (never a directive)\n- `methodological_limitations` — required disclosure of what the diagnostic does NOT establish\n- `data_through` / `data_staleness_days` — self-reported data freshness (EOD, refreshed daily)\n\n`validation://` resources expose the realism trust layer: 18 measured stylized facts\nper asset vs historical reference bands — the falsifiability surface. Recompute\nlocally; trust by independent reproduction.\n\n## Scope & compliance\n\nModel-based scenario simulation. Descriptive, never advisory: no suitability,\ntiming, or ranking claim is made or implied — the agent decides what \"suitable\"\nmeans. Out-of-sample limits are disclosed, not hidden (e.g. the GFC hedge-behaviour\ntest failed and ships as a documented limitation).\n\n## Links\n\n- Capability declaration: <https://crashtestyourstrategy.com/interop> (JSON: [/interop.json](https://crashtestyourstrategy.com/interop.json))\n- Methodology: <https://crashtestyourstrategy.com/methodology>\n- Weekly market-regime outlook (citable, auto-generated): <https://crashtestyourstrategy.com/outlook>\n- Failure-mode ontology: <https://crashtestyourstrategy.com/ontology>\n- llms.txt: <https://crashtestyourstrategy.com/llms.txt>\n- Smithery listing: <https://smithery.ai/servers/nobbefrederic/crashtestyourstrategy>\n\nMaintainer: [@fnobbe](https://github.com/fnobbe) · Operator contact: <https://crashtestyourstrategy.com/contact>\n",
