record_event · MemoryMesh MCP: Risk & Policy

WHAT IT DOES

What record_event does on MemoryMesh

AI agents use record_event to create or update resources in MemoryMesh — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MemoryMesh environment.

WHY IT NEEDS A POLICY

Why record_event needs a policy

With no description available, classification relies solely on the tool name. 'record_event' strongly implies writing/creating a new event entry into the local memory index. Given sibling tools like 'forget_memory', 'pin_memory', and 'graph_memory', this server manages a personal knowledge graph, and 'record_event' likely adds an event to that graph — a Write operation.

From the tool's definition Tool name 'record_event' and empty description. The name suggests creating/writing a new event record to the memory system.

Verdict

record_event Rate-limited

record_event 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches MemoryMesh, so you can run agents against it safely.

FAQ

Questions about record_event

What does the record_event tool do? +

record_event. It is categorised as a Write tool in the MemoryMesh MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on record_event? +

Register the MemoryMesh MCP server in PolicyLayer and add a rule for record_event: 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 MemoryMesh. Nothing to install.

What risk level is record_event? +

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

Can I rate-limit record_event? +

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

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

record_event is provided by the MemoryMesh MCP server (kilhubprojects/memory-mesh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
