## Verdict

Blockscout MCP server answered 99.97% of Glimind's liveness checks over 30 days, better than 40% of MCP servers, with 1060 ms median handshake and 5 outages in 90 days. Its agent-readiness grade is A (100/100) across 16 tools, costing an agent about 5,057 tokens to load. Checked every few minutes; no tool is ever called.
