How do I install the memheaven mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `AUTH_KEY_PEPPER`, `MEMHEAVEN_BEARER_TOKEN`, `JWT_SIGNING_SECRET`, `TOKEN_ENCRYPTION_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Memheaven MCP Server?

Bring MemPalace-style long-term memory to ChatGPT and remote AI agents.

The short version

MemHeaven is a self-hosted remote MCP memory server that gives hosted AI clients searchable long-term memory you own.

AI assistants forget project context across chats and sessions
Built-in memory is useful, but it is usually provider-owned and not an exact, searchable memory layer
Local-first memory tools are powerful, but hosted clients need remote MCP
Users want inspectable, searchable, deletable, portable memory
Coding agents need continuity across sessions, editors, and tools

What it needs from you

Node.js 20+ - npm 10+ - Cloudflare account with Workers, D1, R2, Vectorize, and Workers AI enabled - wrangler authenticated against the target Cloudflare account
