MCP Installation Guidance for Claude Workflow

Todo List

• Read repository CLAUDE.md for guidelines
• Examine existing Claude CI workflow
• Determine MCP installation steps needed
• Provide implementation guidance

---

Important Limitation

I cannot directly modify files in .github/workflows/ due to GitHub App permissions. However, I can provide you with the exact changes needed to install Serena MCP on your Claude workflow.

---

Implementation Instructions

To enable Serena MCP on your Claude CI workflow (.github/workflows/claude.yml), you need to add the following steps before the "Run Claude Code" step:

      # Add these steps after the checkout step and before "Run Claude Code"
      - name: Install UV
        uses: astral-sh/setup-uv@v4
        with:
          version: "latest"
      
      - name: Install Serena
        run: |
          uvx serena install
      
      - name: Configure Serena MCP for Claude
        run: |
          # Create MCP configuration directory
          mkdir -p ~/.config/claude-code/mcp
          
          # Add Serena MCP server configuration
          cat > ~/.config/claude-code/mcp/serena.json <<EOF
          {
            "mcpServers": {
              "serena": {
                "command": "uvx",
                "args": ["serena", "mcp"]
              }
            }
          }
          EOF

Modified Workflow Structure

Your updated .github/workflows/claude.yml should look like this (lines 28-50):

    steps:
      - name: Checkout repository
        uses: actions/checkout@v4
        with:
          fetch-depth: 1

      - name: Install UV
        uses: astral-sh/setup-uv@v4
        with:
          version: "latest"
      
      - name: Install Serena
        run: |
          uvx serena install
      
      - name: Configure Serena MCP for Claude
        run: |
          mkdir -p ~/.config/claude-code/mcp
          cat > ~/.config/claude-code/mcp/serena.json <<EOF
          {
            "mcpServers": {
              "serena": {
                "command": "uvx",
                "args": ["serena", "mcp"]
              }
            }
          }
          EOF

      - name: Run Claude Code
        id: claude
        uses: anthropics/claude-code-action@v1
        with:
          claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
          additional_permissions: |
            actions: read

What This Does

1. Install UV: Uses the official astral-sh/setup-uv action to install UV (a fast Python package installer)
2. Install Serena: Uses uvx to install Serena
3. Configure MCP: Creates the Claude Code MCP configuration file to enable Serena as an MCP server

Next Steps

You'll need to manually edit .github/workflows/claude.yml to add these steps. Once you've made the changes:

1. Commit and push the updated workflow
2. The next time Claude runs, it will have access to Serena MCP capabilities

Note: You can find more information about MCP configuration in the Claude Code documentation.
