AI agents use add_memory to create or update resources in RememberMe — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your RememberMe environment.
This tool creates or stores new memory data entries in a persistent storage system (Qdrant vector database). Creation of data is a Write operation. Severity is medium because unauthorized memory injection could corrupt user context or inject false information into an AI agent's decision-making, but lacks the irreversibility of Destructive operations or financial impact.
From the tool's definition Tool name 'add_memory' indicates creation of new memory entries. Sibling tools include 'delete_memory', 'update_memory', and 'search_memories', confirming this is a memory management system where add_memory creates or stores new data.
Documented attack patterns abuse exactly the kind of access add_memory gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RememberMe, and nothing reaches the server without passing your rules. This is the rule we recommend for add_memory:
{
"version": "1",
"default": "deny",
"tools": {
"add_memory": {
"limits": [
{
"counter": "add_memory_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_memory 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.

add_memory. It is categorised as a Write tool in the RememberMe MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the RememberMe MCP server in PolicyLayer and add a rule for add_memory: 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 RememberMe. Nothing to install.
add_memory 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 add_memory 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 add_memory. 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.
add_memory is provided by the RememberMe MCP server (joexie/remember-me). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from RememberMe, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
