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 Loops.so account to Cowork via Composio Connect, enabling it to send onboarding email to new signups, segment contacts by plan and engagement, schedule a product update campaign, and more such actions on your behalf without compromising your account security. ## Also integrate Loops.so with - [OpenAI Agents SDK](https://composio.dev/toolkits/loops_so/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/loops_so/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/loops_so/framework/claude-code) - [Codex](https://composio.dev/toolkits/loops_so/framework/codex) - [OpenClaw](https://composio.dev/toolkits/loops_so/framework/openclaw) - [Hermes](https://composio.dev/toolkits/loops_so/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/loops_so/framework/cli) - [Google ADK](https://composio.dev/toolkits/loops_so/framework/google-adk) - [LangChain](https://composio.dev/toolkits/loops_so/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/loops_so/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/loops_so/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/loops_so/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/loops_so/framework/crew-ai) ## Connect Loops.so to Claude Cowork ### Connecting Loops.so 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 Loops.so through MCP without you sharing account credentials directly with the agent. ## What is the Loops.so MCP server, and what's possible with it? The Loops.so MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Loops.so account. It provides structured and secure access so your agent can perform Loops.so operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `LOOPS_SO_CREATE_CONTACT` | Create Contact | Tool to add a new contact to your Loops audience.

With a standalone Loops.so MCP server, the agents and LLMs can only access a fixed set of Loops.so tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Loops.so 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 Loops.so tools. ### Can I manage the permissions and scopes for Loops.so while using Tool Router? Yes, absolutely. You can configure which Loops.so 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 Loops.so data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
