Overwing

Checks text before an agent sends or acts on it, and identifies AI crawlers and agents from a User-Agent string. Send a message with the text and get back a verdict and one recommended action: block, redact, review or allow. Answers at once; it is a service, not a conversation. Overwing also makes Tower, clearance for agents operating legacy business systems, which is called over REST or MCP, not A2A.

Skills

• Check text before it ships
  Score a draft, a model's output, or an incoming message. Returns a verdict (pass, fail, review), one recommended action (block, redact, review, allow), and per-rule results with calibrated confidence.
