Free, public, **read-only** [Model Context Protocol](https://modelcontextprotocol.io) server for [VaultRubric](https://vaultrubric.com). VaultRubric publishes evidence-based comparisons of where to keep money: crypto exchanges, hardware and software wallets, high-yield savings accounts, and brokerages/IRAs.

- **Endpoint:** `https://vaultrubric.com/mcp` (Streamable HTTP, JSON-RPC over POST)
- **Auth:** none · **Writes:** none · **Rate limit:** 60 requests/minute per IP
- **Registry name:** `com.vaultrubric/vaultrubric` ([official MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=com.vaultrubric))
- **Docs:** https://vaultrubric.com/developers · **OpenAPI (REST mirror):** https://vaultrubric.com/openapi.json

The server is hosted by VaultRubric, so there is nothing to install. This repo only holds the listing metadata.

## Tools

| Tool | What it returns |
|---|---|
| `list_categories` | Categories and platform counts |
| `search_platforms(query, category)` | Matching platforms with score and data coverage |
| `get_platform(name)` | Sourced facts, per-criterion scores with basis and source URLs, incidents, as-of dates |
| `compare_platforms(platforms, weights)` | 2–6 platforms in one category with optional 0–10 weights. Applies the 75% coverage gate, the 60% hack cap and the too-close-to-call (<3 pts) rule |
| `get_verdict(slug)` | Published answer for a comparison page, e.g. `coinbase-vs-kraken` |
| `check_platform_safety(platform)` | Customer-funds hacks, incidents, regulatory actions, security score, with sources |

Older names `compare` and `is_safe` still work as aliases. Every tool declares an `outputSchema` and returns matching `structuredContent`. Every response includes `"attribution": "Source: VaultRubric (vaultrubric.com)"` and the relevant page URLs. Scoring rules: https://vaultrubric.com/methodology
