Customer.io MCP
Customer.io's first-party hosted Model Context Protocol server. It exposes the full Journeys App API and CDP Data Pipelines API to any MCP client through eight tools — a context primer, a schema browser, three verb-scoped HTTP proxies split so reads can be approved independently of writes and deletes, a two-tool skill library, and an auth-status probe. Authorization is OAuth 2.1 with PKCE and dynamic client registration, bound to the authorizing user's own Customer.io permissions.
