Claude Skills vs. MCP Servers: Choosing the Right Tool for AI Agents

By PulseAugur Editorial · [1 sources] ·

This article explains the difference between Claude Skills and MCP servers for AI agents. Skills are best for providing the agent with knowledge it lacks, such as internal conventions or procedures, and load progressively to minimize context cost. MCP servers are designed for granting agents access to external systems like databases or CRMs, enabling actions with side effects. While MCP servers can be token-intensive, techniques like deferred tool definitions in Claude Code and gateways like Bifröst can reduce this overhead. The author recommends using a skill for knowledge gaps and an MCP server for access needs, often employing both in tandem for comprehensive agent functionality. AI
