Skills vs MCP Debate

Some users suggest using skills and CLI instead of injecting MCP into context, questioning whether skills running in subagents save context

← Back to MCP server that reduces Claude Code context consumption by 98%

The debate over tool integration centers on whether to prioritize skills and CLI commands over direct MCP context injection, with some users dismissing the latter as an outdated and inefficient practice. While proponents of skills favor the potential for subagents to save context, critics warn that avoiding "fat" MCP servers might inadvertently break caching and prove "penny wise, pound foolish" by sacrificing cheaper, information-rich queries. Ultimately, the discussion highlights a technical tension between the perceived modularity of skill-based architectures and the cost-effective performance of cached context.

If this breaks the cache it is penny wise, pound foolish; cached full queries have more information and are cheap. The article does not mention caching; does anyone know? I just enable fat MCP servers as needed, and try to use skills instead.

Does the skill run in a subagent, saving context?
