The SDK architecture extracts and generalizes existing Stacklist MCP code into reusable packages (@acp/core, @acp/enrichment, @acp/mcp) with a CLI, supporting multiple AI providers, filesystem-based storage, tiered enrichment depth levels, and 15 MCP tools for creating, enriching, searching, and managing Atomic Content Objects.","image":null,"stack":{"id":"2e5d1345-7144-4a10-b34a-9d11a4eba127","title":"ACP","url":"https://stacklist.com/c/technology/stack/2e5d1345-7144-4a10-b34a-9d11a4eba127"},"created_at":"2026-04-10T10:30:00.861Z","updated_at":null,"aco":null,"_links":{"self":"/api/public/card/c515e9e0-004a-4967-9705-32996cb57e1e.json","html":"https://stacklist.com/card/c515e9e0-004a-4967-9705-32996cb57e1e","md":"/api/public/card/c515e9e0-004a-4967-9705-32996cb57e1e.md","stack_json":"/api/public/stack/2e5d1345-7144-4a10-b34a-9d11a4eba127.json"}}
