Security Report

4.4

Use Caution4.4High Risk

This is a local, user-controlled VRChat MCP server with keychain-first cookie storage, loopback-only HTTP mode gated by a bearer token, and no evidence of exfiltration, shell execution, or obfuscation in the reviewed code. The main concerns are the optional headless auto-login, which stores the account password and TOTP secret in environment variables and may conflict with VRChat's API guidelines, and broad generated write/delete tools that can take account-changing actions, though these are documented and can be disabled or narrowed. Supply chain analysis found 11 known vulnerabilities in dependencies (0 critical, 7 high severity). Package verification found 1 issue.
