Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks. This guide walks you through the easiest and most secure way to connect your Npm account to Cowork via Composio Connect, enabling it to search for the latest lodash release, list all dependencies for react project, show weekly download stats for a package, and more such actions on your behalf without compromising your account security. ## 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) - [Codex](https://composio.dev/toolkits/npm/framework/codex) - [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) ## Connect Npm to Claude Cowork ### Connecting Npm to Claude Cowork 1. Open Customize In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top. 2. Add the Composio MCP server Click Add custom connector and paste in the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is Claude Cowork? Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools. With Composio Connect, Cowork can securely access apps like Npm through MCP without you sharing account credentials directly with the agent. ## 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 Claude Cowork? Yes, you can. Claude Cowork 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)
