Prism MCP
Mind Palace for AI Agents
A Model Context Protocol server that gives Claude, Cursor, and other AI tools long-term memory that survives across sessions — with semantic search, cognitive routing, a visual dashboard, and the prism-coder LLM fleet for offline tool-calling.
Install
# npx (no install)
npx prism-mcp-server
# or install globally
npm install -g prism-mcp-server && prism-coder# LLM fleet (offline tool-calling — no API key needed)

💾
Persistent memory
Every session feeds the Mind Palace. Next session your AI loads the right context automatically.
🔍
Semantic search
Vector + keyword + graph traversal over your full history. Ask questions, get citations.
🧬
Cognitive routing
Episodic, semantic, and procedural memory stored separately. The router picks where to save and retrieve.
🔄
Drift detection
Detects when your agent drifts from original goals mid-session and self-corrects automatically.
🛡
Local-first
Free tier runs entirely on your machine — SQLite, local embeddings, no API keys, no cloud.
🤖
100% BFCL accuracy
prism-coder models trained specifically for function-calling — 2B through 27B, all at 99.1–100% routing accuracy.
💻
