Health check for a TD instance. Returns app/version/project info.
AI agents call ping to retrieve information from Touchdesigner without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The ping tool only reads and returns information about the application state. It does not create, modify, delete, execute code, or trigger external operations. Despite being part of a server with powerful capabilities (eval_python, exec_python, delete_operator), this specific tool is purely informational and safe, warranting a Read classification with low severity.
From the tool's definition The tool performs a health check that 'Returns app/version/project info.' This is a query operation with no side effects—it retrieves status and metadata about the TouchDesigner instance.
Attacks that exploit this kind of access
Health check for a TD instance. Returns app/version/project info. It is categorised as a Read tool in the Touchdesigner MCP Server, which means it retrieves data without modifying state.
Register the Touchdesigner MCP server in PolicyLayer and add a rule for ping: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Touchdesigner. Nothing to install.
ping is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the ping rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for ping. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ping is provided by the Touchdesigner MCP server (mrinalghosh/touchdesigner-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
