WHAT IT DOES

What replace_tag does on Enhanced Knowledge Graph Memory Server

AI agents use replace_tag 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 replace_tag is rated Medium

The tool creates or modifies data (tag reassignment) across entities. It is Write rather than Destructive because the original tag can be restored or reassigned later. Severity is medium because bulk modification across entities could cause confusion or loss of intended categorization if misused, but the impact is not irreversible or critical to system integrity.

From the tool's definition Tool description states 'Replace a tag with a new tag across all entities' — this modifies metadata (tags) across potentially many stored entities in the knowledge graph.

RECOMMENDED RULE

The rule that runs replace_tag 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 replace_tag, this is the rule to start with:

replace_tag Rate-limited

replace_tag 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.

FAQ

Questions about replace_tag

What does the replace_tag tool do? +

Replace a tag with a new tag across all entities. It is categorised as a Write tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on replace_tag? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for replace_tag: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Enhanced Knowledge Graph Memory Server. Nothing to install.

What risk level is replace_tag? +

replace_tag is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit replace_tag? +

Yes. Add a rate_limit block to the replace_tag rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block replace_tag completely? +

Set action: deny in the PolicyLayer policy for replace_tag. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides replace_tag? +

replace_tag is provided by the Enhanced Knowledge Graph Memory Server MCP server (danielsimonjr/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
