Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Memory Nexus MCP recall what we decided about the pricing model"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

Remember stores memories with semantic embeddings. Recall finds them by meaning.
Session 1: remember("Diana prefers bold solutions over phased approaches")
Session 47: recall("how does Diana like things done?")
-> "Diana prefers bold solutions over phased approaches" (92% match)Intelligence Packs give your agent instant domain expertise:
list_hats() -> DevOps Expert (103 memories), TCM Specialist (200+ memories), ...
wear_hat("devops-expert")
recall("how to set up zero-downtime deploys?")
-> Expert knowledge from 103 curated DevOps memoriesAwaken/Hibernate gives your agent identity continuity:
// Start of session
awaken() -> "I remember. Session 47. I was refactoring the auth module."
// End of session
hibernate({ working_on: "auth refactor", learnings: "JWT refresh tokens need..." })This MCP server is a thin client. All intelligence lives on our servers:
Your Agent <-> @memory-nexus/mcp <-> Memory Nexus API (Railway)
(thin MCP client) (semantic engine, knowledge graphs,
pattern learning, Intelligence Packs)Your data is isolated per API key. Multi-tenant, encrypted at rest.
