# List Deal messages

`deal_records.list_messages`

List messages in one Deal communication thread without changing read state. First call deal_records.list_communications with the same deal_id, then pass an exact returned thread_key.

[Deal administration guide](https://docs.levr.ai/mcp/resources/deal_records.md)

Availability depends on live discovery and your access to the record. Do not infer MCP calls from REST paths.

Operation: read. Required OAuth scopes: mcp.
