Security Report
The ActivityPub MCP server is a well-architected fediverse client with thoughtful security design, including read-only defaults, audit logging, and rate limiting. However, several moderate findings require attention: untrusted content handling could be more consistent, credential handling relies on environment variables without validation of expiration/rotation, and there are gaps in validation of user-supplied URLs and media. The server's security posture is reasonable for its purpose, but users should carefully review SECURITY.md before enabling writes. Supply chain analysis found 10 known vulnerabilities in dependencies (0 critical, 6 high severity). Package verification found 1 issue.
