What should NOT be an MCP server? Developers debate where MCP is overkill
JuicerSocial · reddit · 2026-09-15
A Reddit thread flips the usual MCP conversation: instead of good use cases, the author asks what should NOT be an MCP server.
Dimensions worth weighing include latency, token usage, reliability, unnecessary abstraction, debugging difficulty, security, and added complexity — and where practitioners draw the line between "this should be MCP" and "a plain API, CLI, or direct database connection is simply better." The comments are a practitioner discussion of real-world overkill cases.
