MCPLoadTester is a JMeter load-testing plugin, not a production MCP server. Tool definitions are minimal: 6 tools with basic descriptions (10-50 chars, well below the 194-char baseline) and incomplete schemas. Most parameters lack descriptions entirely. No error handling guidance, no output schema documentation, and no security considerations. The tools appear designed for synthetic load testing (echo, sleep, cpu loops) rather than real agent interactions. Naming is acceptable (verb-noun style) but descriptions are too terse to guide LLM selection. Schemas present but sparse, many parameters undescribed.

• Expand each tool description to 100-200 chars. Example: 'echo' → 'Echo back the provided message, optionally repeated N times. Useful for testing message throughput and latency. Returns the echoed message(s) and elapsed time.'
• Add descriptions to every parameter. Example: 'delayMs' → 'Delay in milliseconds (1-60000). Simulates slow API responses. Includes random jitter ±10% to model real-world variance.'
• Document output schemas for each tool. Example: 'echo' returns {message: string, count: integer, elapsedMs: number}.
• Add error handling guidance. Example: 'divide' → 'Returns error if b=0. Retry is safe (idempotent). If error persists, check input validation.'
• Clarify that this is a load-testing harness, not a production agent tool suite. Consider renaming tools to reflect their synthetic nature (e.g., 'synthetic_echo', 'synthetic_cpu_load') or documenting them as test fixtures, not agent tools.
