Requires the overview snapshot_id and group-local layer ID. Returns file-paged unified patches for that exact snapshot; unavailable provider patches remain explicit. Follow next_cursor with the same parameters. No review or generation is started.

}- CLI Tool
- MCP Server
coderabbit api request "/repositories/$REPOSITORY_ID/pull-requests/$PULL_REQUEST_NUMBER/change-stack/groups/$GROUP_ID/layers/$LAYER_ID/diff?snapshot_id=$SNAPSHOT_ID"
An agent connected to the CodeRabbit MCP server runs this operation as the
get_pull_request_change_stack_layer_diff tool. The connection selects the organization, so the arguments have no org_id or org_name.{
"method": "tools/call",
"params": {
"name": "get_pull_request_change_stack_layer_diff",
"arguments": {
"repository_id": "<repository_id>",
"pull_request_number": 1,
"group_id": "<group_id>",
"layer_id": "<layer_id>",
"snapshot_id": "<snapshot_id>"
}
}
}

Path Parameters
Query Parameters
Organization for a workspace key: the Git-provider organization ID (scope.provider_organization_id) or the CodeRabbit organization ID (scope.id, or id from list organizations). Supply either org_id or org_name, never both. Omit for organization keys and MCP connections.
