Return the member decisions of a cluster, plus the cluster header. Use after get_decision_clusters to drill into a specific topic. Read-only. Returns JSON: { cluster, decisions }.
AI agents call get_cluster_decisions to retrieve information from Trace without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns decision data from a cluster without modifying, deleting, or executing anything. The explicit 'Read-only' designation confirms it has no capability to alter state or trigger external operations. The blast radius of misuse is minimal—an agent could only access existing decision information, not change it.
From the tool's definition Tool name 'get_cluster_decisions' and description states 'Return the member decisions of a cluster' and explicitly 'Read-only'. This is a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_cluster_decisions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trace, and nothing reaches the server without passing your rules. This is the rule we recommend for get_cluster_decisions:
{
"version": "1",
"default": "deny",
"tools": {
"get_cluster_decisions": {}
}
}get_cluster_decisions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Return the member decisions of a cluster, plus the cluster header. Use after get_decision_clusters to drill into a specific topic. Read-only. Returns JSON: { cluster, decisions }. It is categorised as a Read tool in the Trace MCP Server, which means it retrieves data without modifying state.
Register the Trace MCP server in PolicyLayer and add a rule for get_cluster_decisions: 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 Trace. Nothing to install.
get_cluster_decisions 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_cluster_decisions 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_cluster_decisions. 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_cluster_decisions is provided by the Trace MCP server (nikolai-vysotskyi/trace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
