Claude Code: Why I’m Going Back to Cursor | by Tim O'Brien | Benchmarks, Research, and Development | Medium

[strong] "MCP isn't just about tools. A well-designed MCP server exposes prompts (reusable workflows) and resources (structured data), not just callable functions. In Claude Code? The documentation claims MCP prompts are exposed as slash commands using `/mcp__<server>__<prompt>` syntax. But when I tried passing a prompt with parameters, it just... failed." — Article reveals that MCP integration in Claude Code fails to properly handle prompts with parameters, despite MCP being Anthropic's own protocol. This directly contradicts expectations of first-class MCP support.

too many model context protocol servers and LLM allocations on the dance floor

Why is Microsoft doing this or encouraging this bad practice?" — Article directly challenges Microsoft's design decision to remove tool limits, arguing that higher MCP tool counts represent a bad practice rather than an improvement.
