Quick Start Guide
Get your first memory stored and recalled in under 5 minutes.
Prerequisites
Section titled “Prerequisites”Before starting, you’ll need:
- A Nexus-Catalyst account — start a 14-day trial, or use your invitation if you have one
- One of these AI clients: Cursor, Claude Code, or Claude Desktop
- Basic familiarity with using AI chat interfaces
Step 1: Choose Your Platform
Section titled “Step 1: Choose Your Platform”Time: ~5 minutes
- Add the Nexus-Catalyst MCP server in Cursor → Agent Settings → Customize → MCPs → New MCP Server
- Sign in with your NC account when the browser opens (OAuth — no API key to copy)
- Full steps in the Cursor Setup Guide
Time: ~5 minutes
- Install the NC Claude Code plugin and connect the MCP server
- Sign in with your NC account when prompted
- Full steps in the Claude Code Setup Guide
Once a client is connected, give it the Agent instruction set — the standing prompt that makes it use your memory without being asked. Most clients will not call the tools unprompted.
Time: ~3 minutes
- Open Claude Desktop → Customize → Connectors → Add custom connector
- Enter the server URL

recall_context,store_context,search_memories, etc.
Step 2: Store Your First Memory
Section titled “Step 2: Store Your First Memory”Once connected, test storage:
In any connected AI client, ask:
Can you store a memory that I prefer using TypeScript over JavaScript for all new projects?The AI will:
- Call
store_context - Save this preference to your memory store
- Confirm the memory was stored
Step 3: Recall Your Memory
Section titled “Step 3: Recall Your Memory”In a new conversation or different AI client, ask:
What are my programming language preferences?The AI will:
- Call
recall_contextbefore responding - Find your TypeScript preference memory
- Reference it in the response
Expected response:
“Based on your memory, you prefer using TypeScript over JavaScript for all new projects.”
Step 4: Explore Personas (Optional)
Section titled “Step 4: Explore Personas (Optional)”Try asking:
I need help with backend architecture for a new API. Can Jack help me?If recall_context returns a persona_hint, the AI loads Jack’s definition via get_persona_definition. Meet all eighteen built-in personas in the Personas guide.

Troubleshooting
Section titled “Troubleshooting”“Memory not storing” or “Recall returning no results”
Section titled ““Memory not storing” or “Recall returning no results””Possible causes:
- MCP connection not established
- Subscription lapsed (writes pause until payment resumes — check the billing page)
- Network or auth issues
Solutions:
- Check MCP connection status in your client
- Verify you’re signed in to your NC account (re-authenticate from your client if the connection shows as expired)
- See Common Issues
“Persona not activating”
Section titled ““Persona not activating””- Use a persona name explicitly: “Can Jack help me with…”
- Personas load when
recall_contextreturns apersona_hint— see MCP Tools
