WHAT IT DOES

What session_start does on Enhanced Knowledge Graph Memory Server

AI agents use session_start 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 session_start is rated Medium

This tool creates a new session entity in the knowledge graph memory system. It initializes and writes a new SessionEntity record with an ID and timestamps, which is a reversible write operation. There is no code execution, financial action, or destructive behavior involved. Misuse risk is low since it only creates a session tracking record.

From the tool's definition Start a new agent session via AgentMemoryManager. Tracks session lifecycle, enables working memory, and supports session chaining. Returns a SessionEntity with id and timestamps.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

session_start Rate-limited

session_start 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 session_start

What does the session_start tool do? +

Start a new agent session via AgentMemoryManager. Tracks session lifecycle, enables working memory, and supports session chaining. Returns a SessionEntity with id and timestamps. 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 session_start? +

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

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

Can I rate-limit session_start? +

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

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

session_start 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.
