WHAT IT DOES

What sync_transaction does on Basis MCP Server

AI agents use sync_transaction to create or update resources in Basis MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Basis MCP Server environment.

RISK

Why sync_transaction is rated Medium

This tool syncs transaction data to a backend system, which is a write/update operation (propagating state). It does not appear to initiate financial transfers itself, but rather records or reconciles an existing transaction. Confidence is moderate because 'sync' could range from a benign read-like operation to triggering state changes; given the financial context of the server, misuse could have downstream effects.

RECOMMENDED RULE

The rule that runs sync_transaction safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Basis MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sync_transaction, this is the rule to start with:

sync_transaction Rate-limited

sync_transaction stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
