Security Report
Cosmos-MCP is a legitimate MCP server for a personal knowledge graph platform with proper authentication via API keys. The codebase demonstrates reasonable security practices overall, including keychain integration for credential storage on macOS and environment variable support for CI. However, there are notable concerns: unvalidated user data is written directly to the graph database without sanitization, the iMessage sync requires Full Disk Access without explicitly warning users about privacy implications, and credential handling in shell scripts could expose keys in process listings. The server's broad permissions (filesystem read/write, environment variables, network HTTP) are appropriate for its stated purpose as a data aggregation and storage tool. Supply chain analysis found 4 known vulnerabilities in dependencies (0 critical, 4 high severity). Package verification found 1 issue.
