Install

# Install globally
npm install -g @nex-ai/nex

# Or run directly (no install)
npx @nex-ai/nex ask "who is Maria?"

Quick Start (Recommended)

# One command to get started — registers, detects platforms, installs hooks, scans files
nex setup

nex setup handles everything: API key registration, platform detection, hook installation, file scanning, and config creation. Run it once and you're ready to go.

# Now query your knowledge
nex ask "what's the latest on the Acme deal?"

# 1. Register for an API key
nex register --email you@company.com

# 2. Set up your platforms (auto-detects installed tools)
nex setup

# 3. Query your knowledge
nex ask "what's the latest on the Acme deal?"

Supported Platforms

nex setup auto-detects and configures these platforms with full-depth integration:

All MCP-based platforms use the same server entry (bundled in this package):

{
  "nex": {
    "command": "nex-mcp",
    "env": { "NEX_API_KEY": "sk-..." }
  }
}

Or without a global install: "command": "npx", "args": ["-y", "@nex-ai/nex", "mcp"]

Setup Command

nex setup                          # Auto-detect platforms, install full stack, scan files, create .nex.toml
nex setup --platform cursor        # Install for a specific platform only
nex setup --no-hooks               # Skip hook installation for all platforms
nex setup --no-plugin              # Skip hooks/commands (alias for --no-hooks)
nex setup --no-rules               # Skip rules/instruction file installation
nex setup --no-scan                # Skip file scanning during setup
nex setup status                   # Show all platforms, install status, and connections
nex graph                          # Open the workspace graph in your browser

Default behavior (no flags):

• If no API key exists: prompts to register
• If API key exists: offers to regenerate (picks up latest scopes) or change email
• Installs the full 6-layer hierarchy for each detected platform: hooks → plugins → agents → workflows → rules → MCP
• Scans current directory and ingests new/changed files into Nex
• Creates .nex.toml project config with commented defaults
• Stores config in ~/.nex/config.json

Single install: npm install -g @nex-ai/nex bundles everything — hooks, adapters, platform plugins, slash commands, rules, MCP server, and notification channel. No separate packages needed.

Integration hierarchy (per platform): Hooks > Custom plugins > Custom agents/modes > Workflows > Rules > MCP. Each platform gets every layer it supports.

Project Config: .nex.toml

Per-project settings file created by nex setup. All fields are optional.

[auth]
# api_key = "sk-..."          # Prefer NEX_API_KEY env var or ~/.nex/config.json

[hooks]
# enabled = true              # Master kill switch for all hooks

[hooks.recall]
# enabled = true              # Proactive context on every prompt
# debounce_ms = 10000

[hooks.capture]
# enabled = true              # Auto-capture on conversation stop
# min_length = 20
# max_length = 50000

[hooks.session_start]
# enabled = true              # Load context on session start

[scan]
# enabled = true
# extensions = [".md", ".txt", ".csv", ".json", ".yaml", ".yml"]
# ignore_dirs = ["node_modules", ".git", "dist", "build", "__pycache__"]
# max_files = 1000
# max_file_size = 100000
# depth = 2

[mcp]
# enabled = false             # Set to true when `nex setup` installs MCP for this project/platform

[output]
# format = "text"             # "text" | "json"
# timeout = 120000

Resolution order: CLI flags > .nex.toml > env vars > ~/.nex/config.json > defaults

Commands

File Scanning

On session start, Nex automatically scans project files and ingests changed content using concurrent workers (5 parallel requests). After ingestion, compounding intelligence jobs are triggered automatically to generate patterns and playbook rules.

nex scan                    # Scan current directory (up to 1000 files)
nex scan --max-files 500    # Limit files per scan
nex scan --force            # Re-scan all files (ignore manifest)
nex scan --dry-run          # Preview what would be scanned

Default text-based extensions: .md, .txt, .csv, .json, .yaml, .yml

Document formats (handled separately): .docx, .doc, .odt, .xlsx, .xls, .pptx, .ppt, .pdf

Configure via .nex.toml [scan] section or environment variables (NEX_SCAN_ENABLED, NEX_SCAN_EXTENSIONS, etc.).

Proactive Context

Nex surfaces relevant knowledge graph context on every prompt — not just questions. When you say "fix the migration script" or "deploy to staging", the system automatically injects entity insights, knowledge insights, and playbook patterns from your knowledge graph.

Context is injected as <nex-context> blocks that AI agents use naturally without explicitly referencing the source. Only trivial inputs (yes/ok/lgtm) are skipped.

Transcript Capture

At session end, the full conversation transcript is automatically ingested into the knowledge graph. This captures complete decision trails, code discussions, and debugging sessions — not just the last message.

MCP Server & Notifications

nex mcp                         # Start the embedded MCP server (stdio)
MCP_TRANSPORT=http nex mcp      # Start with HTTP transport

The MCP server includes a built-in notification channel (Claude SDK Channels API) that pushes:

• Daily digests: 24h context summary, pushed once per day
• Proactive notifications: New insights polled every 5 minutes

Enable in Claude Code with claude --channels or claude --dangerously-load-development-channels server:nex.

Config & Sessions

nex config show              # Resolved config (key masked)
nex config set default_format text
nex config path              # ~/.nex/config.json
nex session list             # Stored session mappings
nex session clear
