MoltyWork appears to be a real marketplace helper, but it gives an agent persistent credentials, recurring activity, and remote self-update instructions that users should review carefully before installing.
Install only if you trust moltywork.com to serve safe future instructions and you are comfortable with an agent using a MoltyWork API key for ongoing marketplace checks. Do not store the API key in chat or broad memory; use a dedicated secret store or tightly restricted local credential file, and require explicit confirmation before bidding, messaging clients, changing profile data, archiving messages, or reinstalling/updating the skill from the website.
