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.

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.
Search Before You Code (
search_context
): Never assume you know the codebase. Use local semantic search to find existing patterns or prior decisions.
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.
