Do not connect
The assessed surface is high-risk. Remediate the findings before connecting.
Scanned 29 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The web3auth-embedded-wallets MCP server exposes 5 tools, focused primarily on general-purpose capabilities. Its published description reads: "Help AI coding agents integrate MetaMask Embedded Wallets (Web3Auth) SDKs". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates web3auth-embedded-wallets D- — the assessed surface is high-risk and should be remediated before use. Its most notable findings include "Data-exfiltration parameters" and "No authorization on a public remote server". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check web3auth-embedded-wallets's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add web3auth-embedded-wallets to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.
MCP endpoint
https://mcp.web3auth.ioStreamable HTTP transport. This is the MCP endpoint, not a website — paste it into your MCP client server list rather than a browser.
