V0

v0 AI Code Generation (MCP)

Access v0's AI-powered code generation via MCP. When this skill is loaded, the v0 MCP server auto-starts and exposes tools for creating and managing v0 chats.

Prerequisites

Set your v0 API key as an environment variable:

export V0_API_KEY="your-v0-api-key"

To get your v0 API key:

1. Go to v0 account settings
2. Create a new API key
3. Copy and set as environment variable

Quick Start

After loading this skill, list available tools:

skill_mcp(skill_name="v0", list_tools=true)

Then invoke tools:

skill_mcp(skill_name="v0", tool_name="create_chat", arguments='{"prompt": "Create a React dashboard component with a sidebar"}')

Available Tools

create_chat

Create a new v0 chat with a prompt.

Example:

skill_mcp(skill_name="v0", tool_name="create_chat", arguments='{"prompt": "Build a responsive navbar with dark mode toggle"}')

get_chat

Get details about an existing chat.

Example:

skill_mcp(skill_name="v0", tool_name="get_chat", arguments='{"chatId": "abc123"}')

find_chats

Search through your v0 chats.

Example:

skill_mcp(skill_name="v0", tool_name="find_chats", arguments='{"query": "React components"}')

send_message

Continue a conversation in an existing chat.

Example:

skill_mcp(skill_name="v0", tool_name="send_message", arguments='{"chatId": "abc123", "message": "Add dark mode support"}')

Workflow

1. Generate a New Component

# Create a new chat with your requirements
skill_mcp(skill_name="v0", tool_name="create_chat", arguments='{"prompt": "Create a modern pricing table with 3 tiers using Tailwind CSS"}')

# The response includes a chat ID and generated code

2. Iterate on Design

# Send follow-up messages to refine
skill_mcp(skill_name="v0", tool_name="send_message", arguments='{"chatId": "chat-id-here", "message": "Make the recommended tier more prominent with a gradient border"}')

3. Search Previous Work

# Find relevant previous chats
skill_mcp(skill_name="v0", tool_name="find_chats", arguments='{"query": "dashboard"}')

Use Cases

• Component Generation: Create React/Next.js components from descriptions
• UI Prototyping: Rapidly prototype UI ideas
• Design Iteration: Refine designs through conversation
• Code Assistance: Get help with Tailwind CSS, responsive design, etc.

Tips

• Be specific in prompts - include framework (React, Next.js), styling (Tailwind, CSS), and functionality details
• Iterate using send_message rather than creating new chats for refinements
• Search first with find_chats to reuse previous work
• Include context about your existing design system or component patterns

Troubleshooting

"Invalid API key": Ensure V0_API_KEY environment variable is set correctly.

"Rate limit exceeded": v0 has usage limits. Wait a few minutes or check your plan.

"Chat not found": Verify the chat ID is correct. Use find_chats to list available chats.
