Omarchy MCP Server

A Model Context Protocol (MCP) server providing semantic search over Omarchy, Arch Linux, and Hyprland documentation.

Version Information

• Omarchy: v3.8.2 (pinned)

• Omarchy Releases: All versions up to v3.8.2

• Arch Wiki: Latest (updated via script)

• Hyprland Wiki: Latest (updated via script)

Note: This server contains Omarchy v3.8.2 documentation. Some features may differ if you are on a different version.

Prerequisites

• Arch-based Linux system (uses pacman for arch-wiki-docs)

• Docker and Docker Compose

• Git

• 10 GB free disk space

• Internet connection for initial setup

Quick Start

1. Clone the Repository

git clone https://github.com/Zeus-Deus/omarchy-mcp.git
cd omarchy-mcp

2. Run Setup

chmod +x scripts/setup.sh
./scripts/setup.sh

This will take approximately 3-4 minutes and will:

• Restore Omarchy v3.8.2 docs from snapshot

• Download latest Arch Wiki and Hyprland documentation

• Build and start Docker containers

• Process and ingest all documentation into vector database

• Create 8,500+ searchable documentation chunks

Upgrading Omarchy Version

To upgrade to a new Omarchy version:

./scripts/upgrade.sh 3.4.2
docker-compose restart mcp-server

That's it - the script handles everything (download docs, process, ingest, create snapshot).

3. Configure Cursor IDE

Create or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "omarchy-kb": {
      "command": "docker",
      "args": [
        "exec",
        "-i",
        "omarchy-mcp-server",
        "python",
        "/app/mcp_server/main.py"
      ]
    }
  }
}

Important: Restart Cursor completely after adding the configuration.

4. Configure OpenCode

Create or edit ~/.config/opencode/opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "autoupdate": false,
  "mcp": {
    "omarchy-kb": {
      "type": "local",
      "command": [
        "docker",
        "exec",
        "-i",
        "omarchy-mcp-server",
        "python",
        "/app/mcp_server/main.py"
      ]
    }
  }
}

5. Configure Claude Code

Run the following command in your terminal:

claude mcp add --scope user omarchy-kb -- docker exec -i omarchy-mcp-server python /app/mcp_server/main.py

Restart Claude Code after adding the configuration. Verify the server is connected:

claude mcp list

6. Use in Cursor / OpenCode / Claude Code

1. Open your IDE (Cursor, OpenCode, or Claude Code)

2. Switch to Agent mode (click "Ask" dropdown in bottom-left, select "Agent")

3. In the chat, type queries like:

Use omarchy-kb to search for waybar configuration

Or:

How do I configure Hyprland keybindings in Omarchy?

Or:

Use omarchy-kb to tell me what's new in Omarchy version 3.2.0

Available Tools

The MCP server provides these tools:

• search_documentation - Semantic search across all documentation

• find_config_location - Find configuration file paths for applications

• compare_omarchy_vs_arch - Compare Omarchy vs vanilla Arch/Hyprland implementations

• get_server_info - View server statistics and capabilities

Documentation Sources

The knowledge base includes:

Priority System: When conflicts occur, Omarchy documentation takes precedence over Hyprland and Arch.

Updating Documentation

Note: Omarchy documentation and release notes remain at v3.8.2 (pinned version). To update Arch Wiki and Hyprland documentation, re-run the setup script or manually execute the download and processing scripts.

Manual Operations

Stop the Server

docker-compose down

Start the Server

docker-compose up -d

View Logs

docker logs -f omarchy-mcp-server

Rebuild After Code Changes

Troubleshooting

Server Not Connecting in Cursor

• Ensure Docker containers are running: docker ps

• Check server logs: docker logs omarchy-mcp-server

• Verify you are in Agent mode in Cursor (not "Ask" mode)

• Restart Cursor completely after updating config

No Results from Queries

• Verify vector database is populated:

docker exec omarchy-mcp-server python -c "
import chromadb
client = chromadb.HttpClient(host='chromadb', port=8000)
collection = client.get_collection('omarchy_docs')
print(f'Documents: {collection.count()}')
"

• Should show approximately 8,500+ documents

Setup Script Fails

• Ensure Docker daemon is running: systemctl status docker

• Check available disk space: df -h

• Verify internet connection

• Try running steps manually from scripts/setup.sh

Technical Details

• Vector Database: ChromaDB

• Embedding Model: all-MiniLM-L6-v2 (sentence-transformers)

• Chunk Size: 400 words per document chunk

• Search Method: Cosine similarity on embeddings

• Protocol: Model Context Protocol (MCP) via stdio
