GetGraphSchema
shallowio.github.apollographql/graphos-mcp-server · Verify this server
Read the schema (SDL) that is currently published to a graph variant, with its hash and publication time. This is the same read that `rover graph fetch` performs. The response holds the whole document and is not truncated. A large federated graph measured over 800,000 characters, roughly 200,000 tokens, which exceeds the context window of most models. Prefer GetSubgraphSchema, which reads one subgraph at a time, and use this tool only when you need the whole API schema. Provide the graph ID and the variant name.
