WHAT IT DOES

What replace_contract_pdf does on Sanka MCP Server

AI agents use replace_contract_pdf to create or update resources in Sanka MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sanka MCP Server environment.

RISK

Why replace_contract_pdf is rated Medium

The tool creates or modifies data (contract PDF content) but does not irreversibly delete it—the PDF can be replaced again or reverted. It is not Destructive since the contract record itself persists and the action is reversible.

From the tool's definition Tool name contains 'replace' and description explicitly states it 'Replace[s] the PDF of an existing draft Sanka Contract.' This modifies an existing document reversibly (PDF attachment/content).
