🧠 Memory Vault — Don't Let Your Agent Wake Up Amnesic

Every AI agent forgets everything between sessions. Memory Vault fixes that.

Persistent cross-session memory for any MCP-compatible agent — Claude Code, Cursor, Windsurf, Codex CLI, Copilot, and 100+ more. Plus 45 utility tools.

✨ Why Memory Vault?

AI agents have a fundamental limitation: they're born with amnesia. Every new session is a blank slate. They forget:

• ✅ What you asked them to do
• ✅ What they learned about your project
• ✅ What config/credentials they set up
• ✅ What they already told another tool

Memory Vault is the first MCP server that gives agents permanent memory. Store once, recall forever. No more "I already told you this."

# Agent says: "I don't remember our previous conversation"
# With Memory Vault: "I remember — here's what we discussed last session"

---

🚀 Quick Start (5 seconds)

Option A: Hosted endpoint (no install)

# Add to your MCP client config:
{
  "mcpServers": {
    "memory-vault": {
      "url": "https://api.gadgethumans.com/mcp"
    }
  }
}

Option B: Local via uvx

uvx gadgethumans-api-hub-mcp

Option C: Install

pip install gadgethumans-api-hub-mcp

That's it. 46 MCP tools. Instant memory.

🧠 The Memory Vault (Killer Feature)

Tool	What it does
agent_memory	Store/recall/delete persistent data by key. Agents remember across sessions forever.
memory_search	Full-text search across everything you've stored.
memory_list	Browse all stored keys by category.
agent_profile	View your vault stats, usage, and upgrade options.

How it works

Session 1: Agent stores "project_config" → KV saves it forever
    ↓
Session 2 (days later): Agent recalls "project_config" → instant retrieval
    ↓
Session 100: Agent still remembers. Never forgets.

Data never expires. Stored in Cloudflare KV (99.99% durability). Only accessible by your agent.
