## Verdict

Designesy MCP server answered 100% of Glimind's liveness checks over 30 days, better than 42% of MCP servers, with 666 ms median handshake and 4 outages in 90 days. Its agent-readiness grade is A (92/100) across 17 tools, costing an agent about 4,423 tokens to load. Checked every few minutes; no tool is ever called.
