  title: Collections API
  description: |
    Public REST API for the Prisme.ai Collections workspace: named collections
    of structured records with typed schemas, MongoDB-style querying,
    aggregations, and an MCP (JSON-RPC 2.0) endpoint for AI agents.

    Records are isolated per owner (user or agent); a collection can be shared
    with additional agents through its `agent_ids` list. Every write emits an
    audit event.
