- Add fallback guidance for MCP server unavailability - Add published versions tracking (PyPI/MCP Registry → git tags) - Enhance CLAUDE-template.md with 7 practice summaries - Add cross-references between README, MIGRATION-GUIDE, CLAUDE-template - Add troubleshooting section for MCP server failures Fallback options: - GitHub practices (primary) - Local clone access (offline) - CLAUDE.md appendix (emergency) Version tracking: - Link PyPI/MCP Registry v1.4.0 to git tag v1.4.0 (34ca572) - Show latest development vs published versions

+### MCP Server is Down or Unavailable
+
+**Symptoms:** MCP server process crashed, not responding, or cannot start
+
+**Fallback Options:**
+
+**Option 1: GitHub Practices (Recommended)**
+```
+Access practices directly from GitHub:
+https://github.com/ai-4-devops/devops-practices/tree/main/practices
+
+Ask Claude to read practices via GitHub URLs when MCP unavailable.
+```
+
+**Option 2: Local Clone**
+```bash
+# Access practices from local clone
+ls ~/.mcp-servers/devops-practices-mcp/practices/
+
+# Read practice directly
+cat ~/.mcp-servers/devops-practices-mcp/practices/03-02-air-gapped-workflow.md
+```
+
+**Option 3: CLAUDE.md Appendix**
+```
+Projects using the CLAUDE-template.md have a built-in appendix
+with critical practice summaries for emergency fallback.
+
+See: templates/CLAUDE-template.md (Appendix section)
+```
+
+**Prevention:**
+- Use [.mcp.json](.mcp.json) for project-level config (more reliable)
+- Add MCP health check to pre-session checklist
+- Keep local clone updated: `git pull origin main`
+- Monitor logs: `tail -f ~/.cache/claude/mcp-devops-practices.log`
