WHAT IT DOES

What archive_entities does on Enhanced Knowledge Graph Memory Server

AI agents use archive_entities 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 archive_entities is rated Medium

Archiving is a write operation that changes entity status/state in the knowledge graph, making it a Write category tool. Severity is medium because archiving could hide important information from retrieval and might disrupt downstream processes relying on complete entity visibility, but the operation is reversible and does not permanently destroy data.

From the tool's definition Tool description states 'Archive old or low-importance entities', which modifies the state of entities by marking them as archived rather than deleting them.

RECOMMENDED RULE

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

archive_entities Rate-limited

archive_entities 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 Enhanced Knowledge Graph Memory Server, apply this rule, and every archive_entities call is checked against it from then on.

FAQ

Questions about archive_entities

What does the archive_entities tool do? +

Archive old or low-importance 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 archive_entities? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for archive_entities: 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 archive_entities? +

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

Can I rate-limit archive_entities? +

Yes. Add a rate_limit block to the archive_entities 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 archive_entities completely? +

Set action: deny in the PolicyLayer policy for archive_entities. 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 archive_entities? +

archive_entities 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.
