 ## Development Workflow Rules
 
+### Tool Usage Guidelines
+- **Prefer MCP tools over command-line alternatives** - When MCP (Model Context Protocol) tools are available for a task, use them instead of command-line tools
+- **Examples**: Use `mcp_lkernat-gitlab_*` functions instead of `glab` commands, prefer MCP web search over terminal `curl` calls
+- **Benefits**: MCP tools provide more reliable, direct interfaces and better error handling
+- **Fallback**: Only use command-line tools when no MCP alternative exists
+
 ### External Resources & Libraries
 - **Web search is always allowed** - use web search to find solutions, check documentation, verify best practices
 - **Use latest library versions** - always prefer the latest stable versions of external libraries
