Claude Code Plugins

Install DUAL plugins into Claude Code (the CLI) to manage tokens, build integrations, and wire up AI — all through natural conversation. Each plugin bundles slash commands, knowledge skills, and an MCP server connection to the DUAL platform. Designed for terminal-based workflows and headless environments.

Before You Start

All plugins require one environment variable. Set this in your shell profile before installing:

export DUAL_API_KEY="your_api_key"

Get your API key from the Developer Kit page, or by calling POST /auth/login (OTP) to get a JWT token.

How to Install a Plugin

Download the .zip file using the button on any plugin card below.

Set DUAL_API_KEY in your shell profile (e.g. ~/.zshrc or ~/.bashrc) and restart your terminal.

Install via Claude Code CLI: claude plugins add ./dual-developer-kit.zip

The plugin's skills and commands load automatically. No build step needed — the MCP server runs remotely.

Test by running one of the plugin's slash commands (e.g. /my-tokens).

DUAL Token Manager

DUAL AI Toolkit

AI / ML Engineers

Wire up AI to the DUAL platform

Download .zip(44 KB).plugin

Five production-ready patterns for integrating language models with DUAL — token classification, conversational assistants, webhook automation, semantic search, and safety guardrails. Includes scaffold commands, detailed reference guides, and links to companion GitHub repos.

Commands

/setup-classifier

Scaffold an AI token classification pipeline. Choose categories, LLM provider (OpenAI or Anthropic), and output format. Generates batch-capable classifier with structured output.

/setup-chatbot

Scaffold a tool-calling conversational assistant. Pick capabilities (query, transfer, search, wallet info) and generate a complete chatbot with safety confirmations.

/setup-guardrails

Generate AI safety middleware — permission tiers, rate limiting, human-in-the-loop approval queues, and audit logging.

Claude Code vs Cowork Installation

Claude Code (CLI): Install plugins via terminal using claude plugins add for headless and automation workflows.

Cowork (Desktop): Install plugins via drag-and-drop through the Claude desktop app GUI.

Both use the same .zip format and connect to the same MCP servers. View the Claude Plugins page for Cowork-specific installation steps.

About the MCP Server

All three plugins connect to the DUAL platform through the hosted MCP server at https://mcp.blockv.io/mcp. No local setup is needed — the plugins communicate with the remote server, which proxies requests to the DUAL API. Your API key is sent securely via the X-API-Key header on each request.

For configuration details, see the MCP Server documentation and Setup Guide.

Troubleshooting

"Cannot connect to MCP server"

The plugin connects to the hosted MCP server at mcp.blockv.io. Check your internet connection and that the endpoint is reachable.

"Invalid token" or "Unauthorized"

Verify DUAL_API_KEY is set in your shell profile and hasn't expired. Restart Claude Code after changing environment variables.

Tools return "Resource not found"

Some API endpoints may not be available on all network deployments. Check that your API key has the required permissions.

Plugin not showing in Claude Code

Run `claude plugins list` to verify installation. Ensure the .zip file was valid and extracted properly.
