What is MemHeaven?

MemHeaven is a self-hosted remote MCP memory server that gives hosted AI clients like ChatGPT searchable long-term memory you own. It brings MemPalace-style memory to remote agents, deploying on a Cloudflare Free account without VM, Docker, or database administration.

How to use MemHeaven?

FAQ from MemHeaven

How does MemHeaven differ from MemPalace?

MemHeaven explores a remote MCP deployment shape for hosted clients and trusted shared setups, while MemPalace is a local-first memory approach. They are complementary, not replacements.

What are the prerequisites for self-hosting MemHeaven?

You need Node.js 20+, npm 10+, a Cloudflare account with Workers, D1, R2, Vectorize, and Workers AI enabled, and wrangler authenticated against your Cloudflare account.

Which Cloudflare services are used?

The Worker runs the HTTP server; D1 stores metadata and indexes; R2 stores drawer and diary bodies; Vectorize performs semantic search; Workers AI generates embeddings.

Which AI clients are supported?

ChatGPT is confirmed. Claude.ai hosted connectors, local IDE/CLI MCP clients, and Grok with bearer/header auth are expected. VS Code/GitHub Copilot is experimental. Perplexity/Abacus are not applicable.

Is MemHeaven free to use?

Yes, it runs on a Cloudflare Free account, but free-tier limits apply. Heavy usage may require paid Cloudflare usage; review current Cloudflare pricing before broad rollout.
