MCP is dead?
Summary

MCP (Model Context Protocol) introduces context bloat and latency: Linear's 42 tool definitions consume 12,800 tokens, and MCP is 3-9x slower than direct API calls, using 65x more tokens than CLI for a Linear issue lookup. Claude Code's Tool Search with Deferred Loading reduces context usage by 85%+, but architectural overhead remains. The author's team replaced MCP servers with Skills wrapping CLIs, freeing 21K tokens and eliminating init failures, arguing CLI-first and on-demand tool loading are more efficient for most developer workflows.

Key Takeaways
  • Evaluate MCP's context and latency costs per tool; prefer CLI-first or on-demand Skills for agent tool integration to minimize overhead.
Why it matters

For a Solutions Architect building AI agent orchestration, this challenges the assumption that MCP is the universal connector, highlighting context efficiency and performance trade-offs when integrating LLMs with external tools.
