GraphOS MCP Tools
officialGraphOS MCP Tools, now called GraphOS MCP Server, connects assistants to Apollo documentation and graph-building tools. Documentation tools can be used without authentication. Tools that access your graph require a GraphOS API key in the x-api-key header. This is not an OAuth connector; see the official setup examples before using account-specific tools.
What can you do with GraphOS Tools MCP?
- Fetch Apollo docs — Ask your assistant to retrieve Apollo GraphQL documentation pages via the public tool, no authentication needed.
- Query graph schemas — Use to pull your GraphOS graph's schema by providing the graph ID and API key.
- List graph operations — Request to view recent operations and performance data for a specific graph variant.
- Inspect schema checks — Ask to review details of a schema check, including changes and validation results.

Connection
Official documentation explicitly documents public tools plus optional x-api-key for graph-specific tools; not OAuth. Registry domain/publisher and hosted product were verified in the original inventory.
