Security Report
The Diagrams.so MCP server is a thin, transparent client over the public api.diagrams.so REST API with browser/email-based login, no hardcoded credentials, and a documented credentials file with owner-only permissions. Its network_http and file access (credentials file) match its stated purpose, and the tool-name 'data exfiltration' flags for read-only tools are scanner false positives since those tools only send the user's own diagram IDs and prompts to the vendor's API. Minor items to review are the in-tool auto-login email flow and the possibility of unknown-outcome billing retries, but no malicious patterns were found in the visible code. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.
