What it is
A memory service for AI sessions. Conversations, decisions and artifacts are saved to your purmemo account and searched back semantically, so context survives the end of a chat.
Requirements
A purmemo account. The hosted route needs no local install: point your client at https://mcp.purmemo.ai/mcp/messages over streamable-http and sign in through OAuth on first use. Locally, the installer at https://app.purmemo.ai/install sets up the purmemo command, or run npx -y purmemo-mcp with PURMEMO_API_KEY from Settings → API Keys. The npm package is purmemo-mcp, currently 15.7.26, running over stdio on Node. The free plan allows 50 recalls a month with unlimited saves; Pro is $19 a month with both unlimited.
Setup effort
One command plus a key — curl -fsSL https://app.purmemo.ai/install | sh, then supply credentials
