Two Tiny MCP Servers That Reduced Prompt Waste This Week

Two tiny MCP servers were created to reduce prompt waste by addressing structured output failures and tool overload. These servers, schema-pin-mcp and tool-router-mcp, provide practical wins such as fewer silent failures, cleaner receipts for debugging, and less prompt repetition. Engineers can use these small utilities to enforce schema, select tools, and control prompt budgets. This pattern of extracting friction into narrow servers and reusing them across workflows can be trusted.
