GetVariantDetails
An MCP tool from the Apollo GraphOS server, run by Apollo.
Retrieve metadata for a graph variant: its identifier, federation version, the URL of its GraphQL endpoint, and its subgraph inventory (names only). Use this to assess a variant's composition setup, such as subgraph inventory and federation version compliance. Provide the graph ID and variant name (e.g., "production").
Name on the gateway: apollo_graphos__GetVariantDetails.
Parameters
| Name | Type | Description |
|---|---|---|
graphId required | string | |
variant required | string |
How to call it
Through the Smart Gateway, any client can run it by name with call_tool, or let the gateway find it with search_tools:
{
"name": "apollo_graphos__GetVariantDetails",
"arguments": {
"graphId": "…",
"variant": "…"
}
}The first call connects Apollo GraphOS to your account automatically; nothing to set up. About this server.
