MemoryGraph features
- Automatic memory capture. Stores solutions, patterns and decisions automatically as the agent works.
- Graph relationships. Creates typed edges (e.g., SOLVES, DEPENDS_ON) to enable multi-hop, temporal queries.
- Semantic recall. Fuzzy, relevance-based search across stored memories with recall_memories().
- Backend flexibility. Supports SQLite, FalkorDBLite, FalkorDB server, Neo4j, Memgraph and future cloud backend.
- Data portability. Migrate, export to JSON, and rollback memories between backends without lock-in.
- Cloud sync & team workspaces. Managed cloud backend shares memories across devices and teams with SSO support.
Unified MCP Server features
- Zero-storage architecture. Tool calls fetch data directly from source APIs; no data is cached or stored.
- Authorization-first access. All tools require explicit customer authorization before they become callable.
- Bi-directional actions. Agents can read and write data (e.g., update records) where the integration supports it.
- Unified auth handling. OAuth, API-key flows, token refresh and optional embedded sign-in UI are provided out of the box.
- Tool discovery controls. Scope available tools to fit model limits and reduce surface area.
- SDKs & language support. Client SDKs for TypeScript, Python, PHP, Java, C#, Ruby, Go and UI components for React, Vue, Angular, JS.
- Embedded security boundaries. Each connection defines isolated access, with read/write, object and action restrictions.
- Virtual & native webhooks. Unlimited webhook subscriptions with virtual polling for systems lacking native webhooks.
