eve agent with long-term memory powered by Mem0.
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.
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().
Try 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.
