WHAT IT DOES

What capture_to_vault does on tdmcp — TouchDesigner MCP server

AI agents use capture_to_vault to create or update resources in tdmcp — TouchDesigner MCP server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your tdmcp — TouchDesigner MCP server environment.

RISK

Why capture_to_vault is rated Medium

The tool creates new image files and modifies (appends to) markdown documents in an Obsidian vault. These are write operations because they create or modify data reversibly. The severity is medium rather than high because the effects are localized to a gallery/note system without affecting critical infrastructure, though they do persist data to the file system.

From the tool's definition The tool 'captures a preview still from a TOP and appends it to a dated gallery note in the Obsidian vault' — the 'appends' operation creates new files ('writes the PNG image') and modifies existing markdown notes. These are reversible write operations.
