What component_changelog_trail does on tdmcp — TouchDesigner MCP server

RISK

Why component_changelog_trail is rated Medium

This tool creates and appends changelog entries to a revision history trail, which is a write operation. It does not execute code, delete data, move money, or trigger external effects—it purely records version history metadata. The append-only nature means entries cannot be modified once written, but new entries can still be added, making it Write rather than Destructive.

From the tool's definition The tool description explicitly states it 'maintains an append-only per-component revision history as a JSONL trail.' Append-only operations are write-class actions that create or record data reversibly.
