# Muninn - The Universal Memory Layer

Muninn is an advanced per-project memory system designed for AI agents. It uses the **Context Exchange Protocol (CXP)** to provide high-performance, token-efficient context management.

## 🛡️ Security & Privacy (Local-First)

Muninn is designed with a **Privacy-First** philosophy. 
- **Local Storage**: All project indexes and memories are stored **exclusively on the host machine** within the `.muninn/` folder (per project) or `~/.muninn/` (for global settings).
- **No Data Exfiltration**: Muninn **does not transmit** any code, context, or memories to third-party servers or remote APIs. All processing (semantic search, indexing, and context injection) happens locally using the high-performance Rust-based CXP engine.
- **Transparent Control**: Memories are stored as standard Markdown files. You can inspect, edit, or delete them at any time.

## ⚙️ Integration

Muninn operates as an MCP (Model Context Protocol) server. 

### 🚀 The Muninn Protocol (ENFORCED)

As an agent, you MUST follow the "Brain-First" workflow to remain efficient and accurate. The MCP server ensures project safety by validating context before allowing sensitive tool operations.

1.  **Orient Yourself (`brain_check`)**: Call this at the start of every session or when switching projects. It loads the local project index and identifies key files and patterns.
2.  **Search Before You Code (`search_context`)**: Never assume you know the codebase. Use local semantic search to find existing patterns or prior decisions.
3.  **Learn as You Go (`add_memory`)**: Every significant fix, architectural decision, or user preference should be saved locally as a memory.

## 🛠 Tool Reference (MCP)

- **`init_project`**: Initialize a local Muninn Brain in a project directory.
- **`brain_check`**: MANDATORY orientation step. Loads local context and patterns.
- **`add_memory`**: Persist facts and decisions to the local `.muninn/memories` folder.
- **`search_context`**: Query the lo...
