WHAT IT DOES

What graph_upsert does on Kali Security MCP

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

RISK

Why graph_upsert is rated Medium

Creates or modifies graph data reversibly in what appears to be a knowledge/results tracking system.

RECOMMENDED RULE

The rule that runs graph_upsert safely

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

graph_upsert Rate-limited

graph_upsert 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.
