List chains in a rack device, or devices within a specific chain. Parameters: - track_index: Track number (1-based). - device_index: Device number (1-based, default 1). - chain_index: Chain number (1-based) to drill into. 0 = list all chains.
AI agents call get_chain_info to retrieve information from Ableton MCP Extended without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_chain_info performs introspection on the structure of Ableton Live rack devices by querying and listing chains and devices. It accepts only informational parameters (indices) and returns data without creating, modifying, deleting, or executing any actions. This is a straightforward Read operation with minimal security risk.
From the tool's definition Tool description states 'List chains in a rack device, or devices within a specific chain' — a read-only retrieval operation with no modification of data or side effects.
Documented attack patterns abuse exactly the kind of access get_chain_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ableton MCP Extended, and nothing reaches the server without passing your rules. This is the rule we recommend for get_chain_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_chain_info": {}
}
}get_chain_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List chains in a rack device, or devices within a specific chain. Parameters: - track_index: Track number (1-based). - device_index: Device number (1-based, default 1). - chain_index: Chain number (1-based) to drill into. 0 = list all chains. It is categorised as a Read tool in the Ableton MCP Extended MCP Server, which means it retrieves data without modifying state.
Register the Ableton MCP Extended MCP server in PolicyLayer and add a rule for get_chain_info: 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 Ableton MCP Extended. Nothing to install.
get_chain_info 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 get_chain_info 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 get_chain_info. 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.
get_chain_info is provided by the Ableton MCP Extended MCP server (uisato/ableton-mcp-extended). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
