WHAT IT DOES

What add_instance_knowledge does on ProAgentStore

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

RISK

Why add_instance_knowledge is rated Medium

The tool creates or modifies knowledge data within a user's private instance. This is a reversible Write operation (knowledge can be updated or removed), not destructive. The scope is limited to the user's own instance, mitigating blast radius.

From the tool's definition Tool name 'add_instance_knowledge' and description 'Add user-specific knowledge to your private subscribed instance' indicate creation/modification of data on the instance.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_instance_knowledge safely

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

add_instance_knowledge Rate-limited

add_instance_knowledge 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.

The button opens the PolicyLayer dashboard: create your workspace, connect ProAgentStore, apply this rule, and every add_instance_knowledge call is checked against it from then on.
