MCP-native · JSON-RPC 2.0 · Open Protocol

Never re-explain
yourself to an AI.

MindVault interviews you to build a structured knowledge graph — then exposes it as a JSON-RPC 2.0 MCP server. Claude, ChatGPT, or any MCP-compatible AI queries your brain in every conversation.

No credit card. No spam. Just early access.

How it works

Four steps from first interview to Claude knowing your context.

1

AI interviews you

MindVault asks targeted questions. Short-form facts and deeper context, alternated intelligently. You answer — no organizing required.

2

Knowledge graph built

Answers are extracted into structured entries with fact_type, category tags, and freshness timestamps. No raw text dumps.

3

MCP server exposed

Your brain becomes a live JSON-RPC 2.0 endpoint at mindvault.rest/api/mcp. Add it to Claude Desktop in 60 seconds.

Every AI benefits

Claude calls query_knowledge or get_brain_summary in every conversation. Your context, without re-typing it.

MindVault · Live interview session
MindVault
Let's start with something easy. What city do you currently live in, and how long have you been there?
You
Austin, Texas. About 3 years now — moved from Chicago for a job at a startup.
MindVault
Saved. Now when you ask Claude "find me a good taco spot near me," it already knows you're in Austin. What's the startup — still there?
✓ Extracted: Location (Austin, TX), Moved from Chicago, ~3 years, Startup career
You
No, I left 6 months ago. Freelancing now — mostly product design for SaaS companies.
MindVault
Got it. Next time you explain yourself to an AI, you won't have to.
✓ Extracted: Current role (Freelancer), Domain (Product Design / SaaS), Transition 6 months ago

It asks. You answer. Every AI benefits.

No competitor does proactive interviewing. You get a knowledge graph, not just a note dump.

🎙️

Proactive Interviewing

MindVault asks the questions — you don't have to organize anything. Smart question alternation extracts both quick facts and deeper context.

🔌

MCP Native

Connect to Claude, ChatGPT, or any MCP-compatible AI. Your knowledge graph becomes available in every conversation — no copy-pasting context.

🎮

Gamified Capture

Daily streaks, memory milestones, and achievement badges make building your brain feel rewarding. Track 90-day growth, not a completeness score.

📄

Smart Form Filling

Insurance forms, school registrations, tax documents — if your brain has the answer, MindVault fills it in. One approval from you.

The context layer your AI is missing

Every AI conversation starts from scratch. You re-explain your preferences, your history, your constraints. MindVault is a structured knowledge graph that any MCP-compatible AI can query — so the conversation starts where you left off.

Built on the Model Context Protocol — the open standard from Anthropic. Streamable HTTP, JSON-RPC 2.0. No vendor lock-in. Drop it into any agent that speaks MCP.
