MemorySync

MemorySync is a hosted memory layer for AI apps and agents, with a hosted MCP server. Save memories with tags, a source label and an importance hint, then recall them semantically and get ranked results for your prompt context. Features: adaptive retrieval, semantic ranking, context assembly, memory tiering (hot/warm/cold), governance policies, and end-to-end traces. Built-in RBAC, audit logging, tenant isolation, encryption in transit and at rest, and rate limiting. Works with LangChain, LangGraph, OpenAI Agents SDK, Vercel AI SDK, CrewAI, LlamaIndex and more. The MCP server is hosted and closed source. Website: https://memorysync.io. Contact: [email protected].
