WHAT IT DOES

What provenance_stamp does on tdmcp — TouchDesigner MCP server

AI agents use provenance_stamp 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 provenance_stamp is rated Medium

The tool 'Writes a' suggests it creates or modifies data (write operation). Given the incomplete description, confidence is reduced. The severity is medium because writing provenance metadata in a TouchDesigner project has limited blast radius—it modifies project annotations but not critical visual or financial systems. This is reversible and typically low-risk compared to destructive or execute operations.

From the tool's definition Tool name 'provenance_stamp' and description 'Writes a' (incomplete) indicate a write operation that modifies data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs provenance_stamp safely

PolicyLayer is an MCP gateway: it sits between your AI agents and tdmcp — TouchDesigner MCP server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For provenance_stamp, this is the rule to start with:

provenance_stamp Rate-limited

provenance_stamp stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
