An eve agent template with long-term memory powered by Mem0. eve is Vercel's framework for durable backend AI agents; this template wires Mem0 into an eve agent so it remembers facts and preferences about each user across conversations, getting more helpful over time instead of starting from scratch.
Deploy clones this repo and installs the Mem0 integration, which sets MEM0_API_KEY
on your project automatically. Model access uses the Vercel AI Gateway through your
linked project.
The agent has two Mem0-backed tools:
remember— saves a durable fact or preference (mem0.add).recall_memories— searches long-term memory for relevant facts (mem0.search).
The instructions (agent/instructions.md) tell the model to recall before answering
and to remember durable facts. Memory is scoped per user via
ctx.session.auth.current.principalId (see agent/lib/mem0.ts).
The chat channel (agent/channels/eve.ts) ships with placeholderAuth(), the
safe default: local development works, your own Vercel deployments and the eve
TUI can reach the agent, and anonymous browser traffic is blocked in production.
Add your auth provider (Auth.js, Clerk, vercelOidc()) to open it to real
users. Memory is scoped per authenticated user via principalId, so each user
gets their own memory automatically once a provider is in place. For a throwaway
public demo where everyone shares one memory, swap placeholderAuth() for
none().
npm install
vercel env pull # pulls MEM0_API_KEY from your Vercel project
# set AI_GATEWAY_API_KEY, or link a Vercel project for model access
npm run dev # opens the eve development REPLTry it: tell the agent something ("I'm vegetarian and allergic to nuts"), start a new session, and ask "what can I eat?" — it recalls what you told it.
