Connection: Runs on your computer
Transport: stdio
Category: Search & AI memory
You need to fill in: VELIXAR_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: VELIXAR_API_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "memory": {
      "command": "npx",
      "args": [
        "-y",
        "velixar-mcp-server"
      ],
      "env": {
        "VELIXAR_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add memory --env VELIXAR_API_KEY=your-value -- npx -y velixar-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "memory": {
      "command": "npx",
      "args": [
        "-y",
        "velixar-mcp-server"
      ],
      "env": {
        "VELIXAR_API_KEY": "your-value"

  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "memory": {

      "env": {
        "VELIXAR_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Memory safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: VELIXAR_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.4) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Velixar MCP Server

The first cognitive memory server for AI assistants. Not a vector database wrapper — a full reasoning layer that gives your AI persistent memory, a knowledge graph, identity awareness, contradiction detection, and belief tracking across every session.

Works with any Model Context Protocol client: Claude Desktop, Kiro, Cursor, Windsurf, Continue.dev, or custom hosts.

Why This Exists

Every AI assistant starts from zero every conversation. Velixar fixes that — but not by just storing and retrieving text. The MCP server gives your assistant the ability to:

Orient itself in a workspace with a single call — no manual context assembly
Track how beliefs evolve over time and surface when they contradict
Build and traverse a knowledge graph of entities and relationships it discovers
Maintain a persistent identity model of who you are, what you prefer, and how you work
Distill sessions into durable memories automatically, with deduplication
Import and export your entire memory corpus for backup or migration

40 tools. 5 live resources. 19 workflow prompts. One npm install.

Quick Start

npm install -g velixar-mcp-server

Get an API key at velixarai.com/settings/api-keys, then add to your MCP client:

"mcpServers": { "velixar": { "command": "velixar-mcp-server", "env": { "VELIXAR_API_KEY": "vlx_your_key_here" } } } }

Restart your assistant. Done.

Tool Surface

`velixar_capabilities`	Feature list, tool inventory, resource URIs
`velixar_security`	Get or set content scanning mode

Live Resources

Resources are injected into your assistant's context automatically — no tool call needed.

Resource	What it provides
`velixar://system/constitution`	Behavioral rules and cognitive modes for the assistant
`velixar://identity/current`	Your persistent user profile
`velixar://memories/recent`	Most recent memories (compact)
`velixar://memories/relevant`	Contextually relevant memories based on current activity
`velixar://domains/{domain}/shadow_graph`	Knowledge graph view for a specific domain

Workflow Prompts

16 built-in prompts that guide multi-step reasoning workflows:

Orientation — recall prior reasoning, build project context, profile an entity, orient-then-narrow
Conflict — resolve contradictions, identify knowledge gaps
Continuity — trace belief evolution, resume sessions, reconstruct decision paths
Lifecycle — distill sessions, consolidate topic memory, retag recent memories
Identity — summarize user identity, detect preference shifts, align response style
Enterprise — evaluate enterprise fit for a domain

Workspace Isolation

Memories are scoped to workspaces. Your personal project never bleeds into work.

Priority	Source	How
1	`VELIXAR_WORKSPACE_ID` env var	Explicit
2	`.velixar.json` in project root	`{ "workspace_id": "my-project" }`
3	Git root directory name	Automatic

Host Compatibility

Host	Tools	Resources	Prompts
Kiro CLI	✅	✅	✅
Claude Desktop	✅	✅	✅
Cursor	✅	⚠️	—
Windsurf	✅	⚠️	—
Continue.dev	✅	✅	✅

When a host doesn't support resources or prompts, the server degrades gracefully — all tools still work independently.

Environment Variables

Variable	Required	Description
`VELIXAR_API_KEY`	Yes	Your API key (starts with `vlx_`)
`VELIXAR_WORKSPACE_ID`	No	Explicit workspace scope
`VELIXAR_API_URL`	No	Custom API endpoint
`VELIXAR_USER_ID`	No	Explicit end-user identity. Leave unset (recommended): the API derives scope from your key — you see your own memories, same as the dashboard. Set it only when one key serves multiple named end users
`VELIXAR_DEBUG`	No	`true` for verbose logging
`VELIXAR_LOG_FORMAT`	No	`json` for structured Datadog/CloudWatch logging
`VELIXAR_HEALTH_PORT`	No	Port for HTTP health check endpoint

Reliability

Automatic retry with exponential backoff (3 attempts)
Circuit breaker — opens after sustained failures, auto-recovers
Cache fallback — serves stale data during outages rather than failing
Structured logging compatible with Datadog and CloudWatch

SDKs

Use Velixar directly from code:

JavaScript/TypeScript: npm install velixar — docs
Python: pip install velixar — docs

CI/CD Integration

GitHub Actions: velixar-memory-sync — distill PR merges into memories
GitHub Actions: velixar-decision-capture — store issue resolutions as decisions
Webhook: POST /webhook/ci — generic CI event ingestion
