Show HN: MemoryGate – Open-source persistent memory for AI agents via MCP

MemoryGate – Open-source persistent memory for AI agents via MCP is a company in show hn launch.

Profile

I built MemoryGate because I kept watching context vanish. I run multiple AI agents across Claude, ChatGPT, and Cursor. Every time a model updated, a platform changed its API, or a context window rolled over — everything the agent had learned was gone. Preferences, decisions, project history, relationship context. Just... wiped. The fundamental problem: AI memory is trapped inside the platform that hosts the conversation. Your agent's knowledge dies with the session, the model version, or the provider's business decisions. MemoryGate is a persistent semantic memory layer that sits outside any single model or platform. It connects via MCP (Model Context Protocol), so any MCP-compatible agent

The company sits in the show hn launch segment, where it competes on its core product or service.

The company is listed at the Show HN launch stage of development.
