How to give Claude Code persistent memory with 51 MCP tools

The Problem Claude Code uses MEMORY.md files for persistence. 200-line limit, no search, no validation, no multi-agent support. After months of fighting this, I built BrainDB. Setup (2 minutes) Clone, configure, start: git clone https://github.com/beckfexx/BrainDB.git cd BrainDB && cp .env.example .env bun install && bun run start Add to your MCP config (Claude Code settings): { "mcpServers": { "braindb": { "command": "bun", "args": ["run", "src/mcp-client.ts"], "env": { "BRAINDB_URL": " http://localhost:3197 " } } } } What you get (51 tools) Smart Context — Claude loads relevant memories based on CWD and git branch. Decisions that stick — Authoritative memories that supersede conflicting old ones. Session Handovers — Pass context to the next session seamlessly. Contradiction Detection — Flags conflicting stored facts automatically. Nightly Self-Learning — Validates memories against web sources overnight.
