  version: 1.0.0-alpha.1
  description: 'The ContextDB Cloud data plane (hosted alpha). Managed, decision-safe

    agent memory: remember with provenance, recall for grounding, and

    recall_for_action before consequential actions.


    Authentication: `Authorization: Bearer cdb_…` is a project-wide server

    credential. The key determines org and project; requests supply only

    `user_id`, which is a partition key, not end-user authentication.


    This surface is the complete alpha allowlist. Shipped `/v1/forget`

    supports scoped deletion of one memory, one stable entity-and-attribute

    slot, or one verified user partition. Partition erasure requires

    `erase_partition=true`, typed `confirmation` equal to `user_id`, and an

    `Idempotency-Key`. Scoped ID checks make a foreign memory ID

    indistinguishable from a missing one.


    `/mcp` is a Hosted Alpha stateless JSON-RPC 2.0 endpoint over Streamable

    HTTP. Trusted backends may use a project key. Marketplace clients use

    OAuth 2.1 authorization code with S256 PKCE, refresh-token rotation, and a

    server-bound user partition. It exposes tools only, with no sessions, SSE,

    resumability, or server-initiated messages.


    Not production-ready. No SLA.'
