WHAT IT DOES

What results_merge does on Ruflo

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

RISK

Why results_merge is rated Medium

This tool performs data merging using CRDT semantics, which modifies existing data structures in a reversible manner. It does not delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or merely retrieve data (Read).

From the tool's definition Tool name 'results_merge' and description 'Merge results with CRDT' indicate a data modification operation. CRDT (Conflict-free Replicated Data Type) merging is a write operation that combines/modifies data structures.

RECOMMENDED RULE

The rule that runs results_merge safely

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

results_merge Rate-limited

results_merge 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.
