WHAT IT DOES

What register_agent does on Enhanced Knowledge Graph Memory Server

AI agents use register_agent 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 register_agent is rated Medium

This tool writes agent identity metadata to the knowledge graph persistence layer. It creates new agent records or updates existing ones with identity information, type classification, trust level, and capability declarations.

From the tool's definition Tool description states it 'registers agent identity' and 'applies' metadata including type, trust level, and capabilities.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

register_agent Rate-limited

register_agent 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 register_agent

What does the register_agent tool do? +

Register an agent for multi-agent operations with identity metadata. Unlike set_agent_role (which applies a role profile), this registers agent identity with type, trust level, and capabilities. 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 register_agent? +

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

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

Can I rate-limit register_agent? +

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

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

register_agent 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.
