At a Glance & Executive Verdict
LIFE
Knowledge & Memory · Local stdio
Quality: 55/100 (Good) | Auth: API Key required
Deja Vu
Knowledge & Memory · Local stdio
Quality: 69/100 (Great) | Auth: No auth required
Verdict Summary: Choose LIFE if you need specialized Knowledge & Memory tools running via a local process. Choose Deja Vu if your workspace requires Knowledge & Memory integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose LIFE when:
You need dedicated capabilities in the Knowledge & Memory domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
Primary tools included: Modular MCP tools for memory and identity state, Semantic memory with keyword fallback, Drives, needs, relationships, and working threads.
Persistent identity architecture for AI agents. 16 MCP servers covering drives, emotional relationships, semantic memory with decay, working threads, learned patterns, journal, genesis (identity discovery), creative collision engine, forecasting, and voice. Zero dependencies beyond Python 3.8. Built across 938 conversations.
Local memory layer over the session histories coding agents already write (Claude Code, Codex CLI, opencode): lexical search, recall tools, session-start auto-recall, secret redaction at index time, cross-machine sync over SSH.
