Add an internal note to an Intercom conversation. Notes are only visible to team members, not customers.
AI agents use add_conversation_note to create or update resources in Intercom Articles MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Intercom Articles MCP Server environment.
This tool creates and adds data to an existing conversation record. While it modifies data, the operation is reversible (notes can be removed or edited), making it a Write action rather than Destructive.
From the tool's definition The tool description states 'Add an internal note to an Intercom conversation,' which performs a create operation that modifies conversation data by appending a note. This is a reversible write action (notes can typically be edited or deleted).

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