Boring Social Media Publisher

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed social-media publishing connector, but users should treat its MCP link as a posting credential for their connected accounts.

Install only if you are comfortable giving Boring publish authority for the connected social accounts. Keep the MCP link private, review connected accounts before posting, and revoke or regenerate the token from Boring settings if it is exposed or no longer needed.
