GraphOS MCP Tools

official

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.

  • List graph operations — Request list_operations to view recent operations and performance data for a specific graph variant.
  • Inspect schema checks — Ask get_schema_check to review details of a schema check, including changes and validation results.
