Register conversation for automatic triggering (used internally)
AI agents use register_conversation to create or update resources in SAM — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SAM environment.
This tool writes/registers state that controls the automatic triggering and saving of conversation data. While it doesn't delete data (excluding Destructive) or move money (excluding Financial), it modifies the configuration of how conversations are automatically processed. The 'used internally' note suggests it's a foundational operation for the memory system.
From the tool's definition Tool name 'register_conversation' and description 'Register conversation for automatic triggering' indicate the tool creates or modifies registration state for automatic memory management operations.
Documented attack patterns abuse exactly the kind of access register_conversation gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SAM, and nothing reaches the server without passing your rules. This is the rule we recommend for register_conversation:
{
"version": "1",
"default": "deny",
"tools": {
"register_conversation": {
"limits": [
{
"counter": "register_conversation_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}register_conversation 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.

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