WHAT IT DOES

What add_modifier does on Blend Ai

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

RISK

Why add_modifier is rated Medium

An AI agent can call add_modifier faster than any human can review: one bad instruction and it creates or modifies resources in Blend Ai by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_modifier safely

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

add_modifier Rate-limited

add_modifier 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.
