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 Stannp account to Cowork via Composio Connect, enabling it to add new customer to holiday postcard group, import client mailing list from spreadsheet, list all available postcard templates, and more such actions on your behalf without compromising your account security. ## Also integrate Stannp with - [OpenAI Agents SDK](https://composio.dev/toolkits/stannp/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/stannp/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/stannp/framework/claude-code) - [Codex](https://composio.dev/toolkits/stannp/framework/codex) - [OpenClaw](https://composio.dev/toolkits/stannp/framework/openclaw) - [Hermes](https://composio.dev/toolkits/stannp/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/stannp/framework/cli) - [Google ADK](https://composio.dev/toolkits/stannp/framework/google-adk) - [LangChain](https://composio.dev/toolkits/stannp/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/stannp/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/stannp/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/stannp/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/stannp/framework/crew-ai) ## Connect Stannp to Claude Cowork ### Connecting Stannp 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 Stannp through MCP without you sharing account credentials directly with the agent. ## What is the Stannp MCP server, and what's possible with it? The Stannp MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Stannp account. It provides structured and secure access to your direct mail contacts, groups, and templates, so your agent can perform actions like managing recipient lists, importing contacts, and retrieving mailing templates on your behalf. - Organize and manage recipient groups: Easily create new recipient groups and add contacts, helping you segment your mailing lists for targeted direct mail campaigns. - Import bulk recipients efficiently: Let your agent upload and import contacts from CSV or XLS files directly into Stannp, streamlining the process of building large mailing lists. - Retrieve and view contact details: Instantly fetch information on specific contacts or list all your contacts, making it simple to keep track of who’s in your database. - Access and manage templates: Quickly list and review all available Stannp templates, so your agent can select the right one when setting up new campaigns or mailings. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `STANNP_ADD_RECIPIENTS_TO_GROUP` | Add recipients to group | Tool to add existing recipients to a mailing list group.

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