AI agents use add_conversation_tag 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 adding a tag, which is a reversible write operation. While tags can be removed, the action itself creates new data associations. Severity is medium because misuse could cause confusion in conversation organization or unintended visibility/routing, but the effect is limited to metadata and reversible.
From the tool's definition Tool name is 'add_conversation_tag' and description states 'Add a tag to a conversation'. The verb 'add' indicates creation/modification of metadata associated with an existing conversation.
Documented attack patterns abuse exactly the kind of access add_conversation_tag gives an agent:
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 add_conversation_tag:
{
"version": "1",
"default": "deny",
"tools": {
"add_conversation_tag": {
"limits": [
{
"counter": "add_conversation_tag_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_conversation_tag 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.
Free to start. No card required.
Add a tag to 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 add_conversation_tag: 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.
add_conversation_tag 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_conversation_tag 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_conversation_tag. 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_conversation_tag 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.
Free to start. No card required.
