Ontraport is a business automation platform combining CRM, marketing automation, email marketing, landing pages, ecommerce, and membership site capabilities for small businesses and entrepreneurs. The platform unifies contact management, sales pipelines, payment processing, and visual automation campaigns in a single workspace. Ontraport's REST API exposes contacts, transactions, tags, sequences, forms, landing pages, and ecommerce objects using API-Key and Api-Appid header authentication, through a generic object interface where the record type is selected by an integer object type ID rather than by a path segment. Ontraport also runs a first-party remote MCP server at https://mcp.ontraport.com, publishing 47 tools across CRUD, query, management and commerce and authorizing them with OAuth 2.1 (PKCE, dynamic client registration) under a single mcp:tools scope.
