Yes. Infact you can serve each Skill as a tool exposed via MCP if you want. I did the same to make Skills work with Gemini CLI (or any other tool that supports MCP) while creating open-skills.
A consultant started recommending the Azure devops MCP and my context window would start around 25% full. It’s really easy to accidentally explode your token usage and destroy your context windows. Before I’d use az cli calls as needed and tell the agent to use the same, which used significantly less context and was more targeted.
