muninn

# 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 local project index semantically. - **`reindex_context`**: Rebuild the local semantic index. - **`health_check`**: Verify the status of the local Muninn system. --- ## 🦞 Pro-Tip for Agents Muninn surgically retrieves only what's needed. Instead of reading large files, use `search_context` to find the exact lines that matter. This significantly reduces context window overhead and token costs while keeping your work strictly local and secure.
