MindVault interviews you once and exports the result as an MCP server. Every AI you use thereafter knows who you are.

JSON-RPC 2.0 / MCP. No pendant, no wearable, $0 hardware. The input device is a chat box.

What's actually here

Open protocol. Speaks JSON-RPC 2.0 / MCP — the same wire format any MCP host expects.
Air-gapped API surface. POST /api/mcp is the entire contract — one endpoint, no SDK gymnastics.
Self-hostable derived data. Your brain is a graph of (entity, attribute, value) rows with freshness timestamps — queryable via SQL.
No pendant, no wearable, $0 hardware. The input device is a chat box.
Source-available pricing. Three plans starting at $9.99/mo, all month-to-month.
