WHAT IT SOLVES
MCP is hitting production, but your Datadog has zero visibility into what's actually happening inside those tool calls
WHY IT'S INTERESTING
Not a replacement — a gap-filler
Positioned to run alongside Datadog and Sentry, not replace them. Smart move — doesn't fight the incumbents, just fills the blind spot they can't see. For SaaS teams shipping MCP in production, that's exactly the gap
30-second scan, 133+ scanners built in
One curl command runs a free scan — gives you a grade and a ranked fix list. Then it monitors every production tool call in real time and writes up the fix when something breaks. Full pipeline from scan to monitoring, not just another dashboard
「Agents won't say your MCP broke. Spanly will.」
TECH GUESS
CLI + SDK on GitHub, scanners probably Python or Go, likely a React frontend
