Get the splits for a transaction. Returns the split details if the transaction has been split into multiple parts. Args: transaction_id: The ID of the transaction to get splits for Returns: Split information for the transaction, or empty if not split.
AI agents call get_transaction_splits to retrieve information from Monarch without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing split information for a transaction. It performs a read-only operation that returns data without creating, modifying, deleting, or executing any operations. The action is passive data retrieval, fitting the Read category. Severity is low because retrieving transaction split details poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'get_transaction_splits' and description 'Get the splits for a transaction' and 'Returns the split details' indicate data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_transaction_splits gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Monarch, and nothing reaches the server without passing your rules. This is the rule we recommend for get_transaction_splits:
{
"version": "1",
"default": "deny",
"tools": {
"get_transaction_splits": {}
}
}get_transaction_splits is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the splits for a transaction. Returns the split details if the transaction has been split into multiple parts. Args: transaction_id: The ID of the transaction to get splits for Returns: Split information for the transaction, or empty if not split. It is categorised as a Read tool in the Monarch MCP Server, which means it retrieves data without modifying state.
Register the Monarch MCP server in PolicyLayer and add a rule for get_transaction_splits: 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 Monarch. Nothing to install.
get_transaction_splits 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_transaction_splits 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_transaction_splits. 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_transaction_splits is provided by the Monarch MCP server (robcerda/monarch-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
