Maindex is a structured memory service — an API and MCP server that gives AI agents (and their humans) a persistent, relational knowledge store. Think of it as the long-term memory your LLMs have been missing.
We're currently in closed beta, offering API keys and dashboard access to a small group of early users and builders.
Drop your email and we'll reach out with an invite when your spot opens up.
What you get
Full REST API and MCP access. Create, tag, link, and search memories. Multi-tenant isolation. Revision history. Full-text search with relational associations that surface context you didn't know you needed.
Who it's for
Developers building agentic systems. Teams who want their AI to remember across sessions. Anyone who's tired of re-explaining context to their tools. If you're building with LLMs and need persistent memory — this is for you.
