Update the assignee of a conversation
AI agents use update_conversation_assignee to create or update resources in Frontapp MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frontapp MCP Server environment.
This tool modifies conversation state by changing who is assigned to handle it. This is a Write action—it creates or modifies data reversibly. While reassigning conversations could have operational impact (e.g., misdirecting customer communications), it is not destructive, financial, or code-execution based.
From the tool's definition Tool name 'update_conversation_assignee' and description 'Update the assignee of a conversation' indicate modification of conversation metadata. This is a reversible state change (assignee can be reassigned), not deletion or destruction.

PolicyLayer is an MCP gateway — it sits between your AI agents and Frontapp MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for update_conversation_assignee:
{
"version": "1",
"default": "deny",
"tools": {
"update_conversation_assignee": {
"limits": [
{
"counter": "update_conversation_assignee_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_conversation_assignee 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.

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