# How to integrate Npm MCP with Codex ```json { "title": "How to integrate Npm MCP with Codex", "toolkit": "Npm", "toolkit_slug": "npm", "framework": "Codex", "framework_slug": "codex", "url": "https://composio.dev/toolkits/npm/framework/codex", "markdown_url": "https://composio.dev/toolkits/npm/framework/codex.md", "updated_at": "2026-05-12T10:20:25.139Z" } ``` ## Introduction Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Npm MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Npm with - [OpenAI Agents SDK](https://composio.dev/toolkits/npm/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/npm/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/npm/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/npm/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/npm/framework/openclaw) - [Hermes](https://composio.dev/toolkits/npm/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/npm/framework/cli) - [Google ADK](https://composio.dev/toolkits/npm/framework/google-adk) - [LangChain](https://composio.dev/toolkits/npm/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/npm/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/npm/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/npm/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/npm/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 Npm to Codex ### How to install Npm 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 Npm MCP server, and what's possible with it? The Npm MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Npm account. It provides structured and secure access to your Npm ecosystem, so your agent can perform actions like searching for packages, retrieving metadata, managing dependencies, publishing new versions, and analyzing project stats on your behalf. - Package discovery and search: Instantly ask your agent to look up packages, find alternatives, or fetch the latest releases for specific libraries. - Retrieve package metadata: Let your agent pull detailed information about any Npm package, including version history, maintainers, and dependencies. - Automated dependency management: Have your agent analyze and update dependencies, check for outdated packages, or suggest upgrades to keep your project secure and efficient. - Publishing and versioning: Enable your agent to publish new package versions, update package details, or manage release workflows directly through Npm. - Project insights and stats: Get your agent to surface download counts, popularity trends, or other analytics on package usage to inform your development decisions. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `NPM_DELETE_USER_TOKEN_LEGACY` | Delete User Token (Legacy) | Tool to delete a user authentication token using the legacy endpoint.

With a standalone Npm MCP server, the agents and LLMs can only access a fixed set of Npm tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Npm 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 Npm tools. ### Can I manage the permissions and scopes for Npm while using Tool Router? Yes, absolutely. You can configure which Npm 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 Npm 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)
