List placeholders for a specific SendForSign template by templateKey.
AI agents call sfs_list_placeholders to retrieve information from SendForSign MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays placeholder information from an existing template, which is a read-only operation with no side effects. It does not create, modify, delete, or execute any operations. The low severity reflects that placeholder metadata exposure poses minimal risk to confidentiality or system integrity.
From the tool's definition Tool description states 'List placeholders' — a query operation that retrieves template metadata. The server description emphasizes 'read template content' without mentioning modifications. No delete, create, execute, or financial operations are described.
