Twitter Post

Security checks across malware telemetry and agentic risk

Overview

This skill does what it says: it posts user-provided content to Twitter/X using documented OAuth credentials, with no evidence of hidden or unrelated behavior.

Install only if you want the agent to be able to post from the configured Twitter/X account. Use dedicated, least-privileged Twitter credentials where possible, keep the tokens out of shared configs and logs, test with TWITTER_DRY_RUN=1, and confirm the final tweet text before publishing.

Medium

Category: MCP Least Privilege
Confidence: 85% confidence
Finding: The skill explicitly requires access to sensitive environment variables containing Twitter API credentials, but no declared permissions are present to inform or constrain that access. This creates a security transparency and governance gap: users or platforms may not realize the skill can read secrets and use them to perform authenticated actions on an external account.
