[EXPERIMENTAL] List all activations (syndications) for a specific segment. Requires both parent_segment_id and segment_id parameters. Use list_parent_segments and list_segments first to find available IDs.
AI agents call list_activations to retrieve information from Treasure Data MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries existing activation/syndication data. The tool retrieves information without creating, modifying, deleting, or executing operations with side effects. The experimental designation and requirement to first discover parent_segment_id and segment_id parameters further confirm this is a safe data retrieval function.
From the tool's definition The tool 'list_activations' retrieves and lists activation records ('List all activations') for a segment. It performs a query operation with no modification or deletion of data, returning information about existing syndications.
Documented attack patterns abuse exactly the kind of access list_activations gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Treasure Data MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_activations:
{
"version": "1",
"default": "deny",
"tools": {
"list_activations": {}
}
}list_activations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

[EXPERIMENTAL] List all activations (syndications) for a specific segment. Requires both parent_segment_id and segment_id parameters. Use list_parent_segments and list_segments first to find available IDs. It is categorised as a Read tool in the Treasure Data MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Treasure Data MCP Server MCP server in PolicyLayer and add a rule for list_activations: 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 Treasure Data MCP Server. Nothing to install.
list_activations 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 list_activations 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 list_activations. 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.
list_activations is provided by the Treasure Data MCP Server MCP server (treasure-data/td-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Treasure Data MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
