And MCP makes the experience even better. With V0 MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate V0 with - [ChatGPT](https://composio.dev/toolkits/v0/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/v0/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/v0/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/v0/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/v0/framework/claude-cowork) - [Cursor](https://composio.dev/toolkits/v0/framework/cursor) - [VS Code](https://composio.dev/toolkits/v0/framework/vscode) - [OpenCode](https://composio.dev/toolkits/v0/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/v0/framework/openclaw) - [Hermes](https://composio.dev/toolkits/v0/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/v0/framework/cli) - [Google ADK](https://composio.dev/toolkits/v0/framework/google-adk) - [LangChain](https://composio.dev/toolkits/v0/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/v0/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/v0/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/v0/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/v0/framework/crew-ai) ## TL;DR ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect V0 to Codex ### How to install V0 MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## What is the V0 MCP server, and what's possible with it? The V0 MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your V0 account. It provides structured and secure access to your V0 projects and chat-powered workflows, so your agent can perform actions like generating code, managing web projects, retrieving chat histories, and facilitating AI-driven conversations on your behalf. - AI-powered chat completions: Instantly generate conversational replies or code suggestions using V0's advanced chat models tailored for web development workflows. - Retrieve and manage chat sessions: List and access your previous AI-assisted chat threads, including support for filtering favorites and paginated results. - Project discovery and management: Fetch a complete list of your web development projects, making it easy for your agent to interact with or summarize project data. - Integrated development automation: Seamlessly combine chat capabilities and project management to automate code generation, troubleshooting, or project setup tasks. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `V0_ASSIGN_CHAT_TO_PROJECT` | Assign Chat To Project | Tool to assign a chat to a project.

With a standalone V0 MCP server, the agents and LLMs can only access a fixed set of V0 tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from V0 and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Codex? Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right V0 tools. ### Can I manage the permissions and scopes for V0 while using Tool Router? Yes, absolutely. You can configure which V0 scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your V0 data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
