How do I install the graph mem 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 `RAILS_ENV`, `RAILS_MASTER_KEY`, `OLLAMA_HOST`, `OLLAMA_URL`, `DATABASE_URL`, `DB_BACKUP_HOST_PATH` 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 the server does

GraphMem provides persistent, structured storage for knowledge entities, their relationships, and observations. It's designed as an MCP server that enables AI assistants to maintain memory across sessions, build domain-specific knowledge graphs, and effectively reference past interactions.

More MCP options

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
