GraphOS MCP Tools
GraphOS 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.
