AI agents use record to create or update resources in Memory-Plus — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Memory-Plus environment.
The tool's name and position among memory management utilities suggest it writes/records data into the RAG memory store. While the description is empty (reducing confidence slightly), the context of a memory system with complementary read (retrieve), write (record/update), and delete operations indicates this modifies stored data.
From the tool's definition Tool is named 'record' on a memory storage server with sibling tools including 'record_memory', 'retrieve_memory', 'update', and 'delete'. The pattern indicates this creates or adds data to persistent storage.
Documented attack patterns abuse exactly the kind of access record gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Memory-Plus, and nothing reaches the server without passing your rules. This is the rule we recommend for record:
{
"version": "1",
"default": "deny",
"tools": {
"record": {
"limits": [
{
"counter": "record_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}record 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.

record. It is categorised as a Write tool in the Memory-Plus MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Memory-Plus MCP server in PolicyLayer and add a rule for record: 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 Memory-Plus. Nothing to install.
record is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the record 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.
Set action: deny in the PolicyLayer policy for record. 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.
record is provided by the Memory-Plus MCP server (yuchen20/memory-plus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
