AI agents use conversation_export to create or update resources in Proxima — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Proxima environment.
An AI agent can call conversation_export faster than any human can review — one bad instruction and it creates or modifies resources in Proxima by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access conversation_export gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Proxima, and nothing reaches the server without passing your rules. This is the rule we recommend for conversation_export:
{
"version": "1",
"default": "deny",
"tools": {
"conversation_export": {
"limits": [
{
"counter": "conversation_export_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}conversation_export 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.

conversation_export. It is categorised as a Write tool in the Proxima MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Proxima MCP server in PolicyLayer and add a rule for conversation_export: 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 Proxima. Nothing to install.
conversation_export 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 conversation_export 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 conversation_export. 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.
conversation_export is provided by the Proxima MCP server (zen4-bit/proxima). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
