WHAT IT DOES

What add_tags does on Enhanced Knowledge Graph Memory Server

AI agents use add_tags to create or update resources in Enhanced Knowledge Graph Memory Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced Knowledge Graph Memory Server environment.

RISK

Why add_tags is rated Medium

This tool creates or modifies metadata (tags) associated with entities in the knowledge graph, which is a reversible write operation. It does not delete data (not Destructive), execute external code (not Execute), move funds (not Financial), or merely retrieve information (not Read).

From the tool's definition Tool name 'add_tags' combined with description 'Add tags to an entity' indicates a modification operation that writes metadata to existing knowledge graph entities. The server context confirms this is a knowledge graph memory system with tagging capabilities.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_tags safely

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

add_tags Rate-limited

add_tags 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.
