Fast search of the locally cached timeline index. Queries audio clip names and track names.
AI agents call search_timeline to retrieve information from Pro Tools MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about audio clips and tracks from an existing cached index. It has no side effects, does not modify or delete data, and does not execute commands. It is a simple query/search operation that fits the Read category. The local-only scope and read-only nature justify low severity.
From the tool's definition Tool performs 'fast search of the locally cached timeline index' and 'queries audio clip names and track names' — purely retrieval operations with no modification, deletion, or execution of code.
Documented attack patterns abuse exactly the kind of access search_timeline gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pro Tools MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_timeline:
{
"version": "1",
"default": "deny",
"tools": {
"search_timeline": {}
}
}search_timeline is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fast search of the locally cached timeline index. Queries audio clip names and track names. It is categorised as a Read tool in the Pro Tools MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Pro Tools MCP Server MCP server in PolicyLayer and add a rule for search_timeline: 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 Pro Tools MCP Server. Nothing to install.
search_timeline 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 search_timeline 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 search_timeline. 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.
search_timeline is provided by the Pro Tools MCP Server MCP server (skrul/protools-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pro Tools MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
