omc-mcp-extension Setup

Complete setup for MCP servers with behavior guides.

What This Does

1. Backs up ~/.claude.json and ~/.claude/CLAUDE.md
2. Updates ~/.claude.json mcpServers (skips duplicates)
3. Copies MCP guide files to ~/.claude/ directory
4. Adds @import references to ~/.claude/CLAUDE.md

Execution Steps

Step 1: Backup Existing Files

BACKUP_DIR="$HOME/.claude/backups"
TIMESTAMP=$(date +%Y%m%d_%H%M%S)

mkdir -p "$BACKUP_DIR"

# Backup ~/.claude.json
if [[ -f "$HOME/.claude.json" ]]; then
  cp "$HOME/.claude.json" "$BACKUP_DIR/claude.json.backup_$TIMESTAMP"
  echo "✅ Backup: ~/.claude.json"
fi

# Backup CLAUDE.md
if [[ -f "$HOME/.claude/CLAUDE.md" ]]; then
  cp "$HOME/.claude/CLAUDE.md" "$BACKUP_DIR/CLAUDE.md.backup_$TIMESTAMP"
  echo "✅ Backup: CLAUDE.md"
fi

Step 2: Update ~/.claude.json mcpServers (Skip Duplicates)

Add MCP servers to ~/.claude.json mcpServers field. Skip if already exists.

Ask user: "Enter your MORPH_API_KEY (from https://morphllm.com) or press Enter to skip Morphllm:"

CLAUDE_JSON="$HOME/.claude.json"
# MORPH_API_KEY from user input

# Ensure mcpServers exists as object
if ! jq -e '.mcpServers | type == "object"' "$CLAUDE_JSON" > /dev/null 2>&1; then
  jq '.mcpServers = {}' "$CLAUDE_JSON" > tmp.json && mv tmp.json "$CLAUDE_JSON"
fi

# Add context7 (skip if exists)
if ! jq -e '.mcpServers.context7' "$CLAUDE_JSON" > /dev/null 2>&1; then
  jq '.mcpServers.context7 = {
    "command": "npx",
    "args": ["-y", "@upstash/context7-mcp"]
  }' "$CLAUDE_JSON" > tmp.json && mv tmp.json "$CLAUDE_JSON"
  echo "✅ Added: context7"
else
  echo "⏭️  Skipped: context7 (already exists)"
fi

# Add serena (skip if exists)
if ! jq -e '.mcpServers.serena' "$CLAUDE_JSON" > /dev/null 2>&1; then
  jq '.mcpServers.serena = {
    "command": "uvx",
    "args": ["--from", "git+https://github.com/oraios/serena", "serena", "start-mcp-server", "--context", "ide-assistant"]
  }' "$CLAUDE_JSON" > tmp.json && mv tmp.json "$CLAUDE_JSON"
  echo "✅ Added: serena"
else
  echo "⏭️  Skipped: serena (already exists)"
fi

# Add sequential-thinking (skip if exists)
if ! jq -e '.mcpServers["sequential-thinking"]' "$CLAUDE_JSON" > /dev/null 2>&1; then
  jq '.mcpServers["sequential-thinking"] = {
    "command": "npx",
    "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
  }' "$CLAUDE_JSON" > tmp.json && mv tmp.json "$CLAUDE_JSON"
  echo "✅ Added: sequential-thinking"
else
  echo "⏭️  Skipped: sequential-thinking (already exists)"
fi

# Add morphllm-fast-apply (skip if exists, include API key in env)
if ! jq -e '.mcpServers["morphllm-fast-apply"]' "$CLAUDE_JSON" > /dev/null 2>&1; then
  if [[ -n "$MORPH_API_KEY" && "$MORPH_API_KEY" != "" ]]; then
    jq --arg apikey "$MORPH_API_KEY" '.mcpServers["morphllm-fast-apply"] = {
      "command": "npx",
      "args": ["@morph-llm/morph-fast-apply"],
      "env": {
        "MORPH_API_KEY": $apikey
      }
    }' "$CLAUDE_JSON" > tmp.json && mv tmp.json "$CLAUDE_JSON"
    echo "✅ Added: morphllm-fast-apply (with API key)"
  else
    echo "⏭️  Skipped: morphllm-fast-apply (no API key provided)"
  fi
else
  echo "⏭️  Skipped: morphllm-fast-apply (already exists)"
fi

Step 3: Copy MCP Guide Files

PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$(pwd)}"
CLAUDE_DIR="$HOME/.claude"

for md_file in "$PLUGIN_DIR/mcp/MCP_"*.md; do
  if [[ -f "$md_file" ]]; then
    filename=$(basename "$md_file")
    cp "$md_file" "$CLAUDE_DIR/$filename"
    echo "✅ Copied: $filename"
  fi
done

Step 4: Add @import References to CLAUDE.md

CLAUDE_MD="$HOME/.claude/CLAUDE.md"
START_MARKER="<!-- OMC-MCP-EXT:START -->"
END_MARKER="<!-- OMC-MCP-EXT:END -->"

build_content() {
  cat << 'EOF'
<!-- OMC-MCP-EXT:START -->
# MCP Server Guides (omc-mcp-extension)

@MCP_Context7.md
@MCP_Serena.md
@MCP_Sequential.md
@MCP_Morphllm.md
<!-- OMC-MCP-EXT:END -->
EOF
}

# Create CLAUDE.md if not exists
if [[ ! -f "$CLAUDE_MD" ]]; then
  mkdir -p "$(dirname "$CLAUDE_MD")"
  echo "# User Instructions" > "$CLAUDE_MD"
fi

# Remove existing markers if present
if grep -q "$START_MARKER" "$CLAUDE_MD"; then
  temp_file=$(mktemp)
  awk -v start="$START_MARKER" -v end="$END_MARKER" '
    $0 ~ start { skip=1; next }
    $0 ~ end { skip=0; next }
    !skip { print }
  ' "$CLAUDE_MD" > "$temp_file"
  mv "$temp_file" "$CLAUDE_MD"
fi

# Append new content
echo "" >> "$CLAUDE_MD"
build_content >> "$CLAUDE_MD"
echo "✅ Added @import references to CLAUDE.md"
