MCP Registry scan shows under 50% clean anonymous handshakes

By PulseAugur Editorial · [1 sources] ·

A recent scan of the MCP Registry revealed that less than half of the 9,991 remote endpoints completed a clean anonymous handshake. Of the remaining endpoints, a significant portion are authenticated by design and correctly return a 401 status, while others are either down or auth-gated without clear indication. The analysis also highlighted the substantial token size of the tools/list payload, which clients load before user interaction, with some servers advertising an exceptionally large number of tools.
