omni-cortex 1.0.1

Universal Memory MCP for Claude Code - dual-layer activity logging and knowledge storage

Omni Cortex MCP

A universal memory system for Claude Code that combines activity logging with intelligent knowledge storage.

Features

• Zero Configuration: Works out of the box - just install and run setup
• Dual-Layer Storage: Activity logging (audit trail) + Knowledge store (memories)
• 15 MCP Tools: Full-featured API for memory management, activity tracking, and session continuity
• Semantic Search: AI-powered search using sentence-transformers (optional)
• Hybrid Search: Combines keyword (FTS5) + semantic search for best results
• Full-Text Search: SQLite FTS5-powered keyword search with smart ranking
• Auto-Categorization: Automatic memory type detection and tag suggestions
• Session Continuity: "Last time you were working on..." context
• Importance Decay: Frequently accessed memories naturally surface
• Auto Activity Logging: Automatically logs all tool calls via hooks

Installation

Quick Install (Recommended)

# Install the package
pip install omni-cortex

# Run automatic setup (configures MCP server + hooks)
omni-cortex-setup

That's it! Omni Cortex will now:

• Automatically log all Claude Code tool calls
• Provide memory tools (cortex_remember, cortex_recall, etc.)
• Create a per-project database at .omni-cortex/cortex.db

With Semantic Search

For AI-powered semantic search capabilities:

pip install omni-cortex[semantic]
omni-cortex-setup

From Source

git clone https://github.com/AllCytes/Omni-Cortex.git
cd omni-cortex
pip install -e ".[semantic]"
python -m omni_cortex.setup

Manual Configuration

If you prefer manual setup, add to ~/.claude.json:

{
  "mcpServers": {
    "omni-cortex": {
      "command": "python",
      "args": ["-m", "omni_cortex.server"]
    }
  }
}

And optionally configure hooks in ~/.claude/settings.json for activity logging:

{
  "hooks": {
    "PreToolUse": [{
      "type": "command",
      "command": "python -m omni_cortex.hooks.pre_tool_use"
    }],
    "PostToolUse": [{
      "type": "command",
      "command": "python -m omni_cortex.hooks.post_tool_use"
    }]
  }
}

Uninstall

omni-cortex-setup --uninstall
pip uninstall omni-cortex

Tools

Memory Tools (6)

Tool	Description
cortex_remember	Store information with auto-categorization
cortex_recall	Search memories (modes: keyword, semantic, hybrid)
cortex_list_memories	List memories with filters and pagination
cortex_update_memory	Update memory content, tags, or status
cortex_forget	Delete a memory
cortex_link_memories	Create relationships between memories

Activity Tools (3)

Tool	Description
cortex_log_activity	Manually log an activity
cortex_get_activities	Query the activity log
cortex_get_timeline	Get a chronological timeline

Session Tools (3)

Tool	Description
cortex_start_session	Start a new session with context
cortex_end_session	End session and generate summary
cortex_get_session_context	Get context from previous sessions

Utility Tools (3)

Tool	Description
cortex_list_tags	List all tags with usage counts
cortex_review_memories	Review and update memory freshness

Memory Types

Memories are automatically categorized into:

• general - General notes and information
• warning - Cautions, things to avoid
• tip - Tips, tricks, best practices
• config - Configuration and settings
• troubleshooting - Debugging and problem-solving
• code - Code snippets and algorithms
• error - Error messages and failures
• solution - Solutions to problems
• command - CLI commands
• concept - Definitions and explanations
• decision - Architectural decisions

Storage

• Per-project: .omni-cortex/cortex.db in your project directory
• Global: ~/.omni-cortex/global.db for cross-project search

Configuration

Create .omni-cortex/config.yaml in your project:

schema_version: "1.0"
embedding_enabled: true
decay_rate_per_day: 0.5
freshness_review_days: 30
auto_provide_context: true
context_depth: 3
