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 Echtpost account to Cowork via Composio Connect, enabling it to show me all postcard templates available, list templates for confidential document delivery, get preview links for secure message templates, and more such actions on your behalf without compromising your account security. ## Also integrate Echtpost with - [OpenAI Agents SDK](https://composio.dev/toolkits/echtpost/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/echtpost/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/echtpost/framework/claude-code) - [Codex](https://composio.dev/toolkits/echtpost/framework/codex) - [OpenClaw](https://composio.dev/toolkits/echtpost/framework/openclaw) - [Hermes](https://composio.dev/toolkits/echtpost/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/echtpost/framework/cli) - [Google ADK](https://composio.dev/toolkits/echtpost/framework/google-adk) - [LangChain](https://composio.dev/toolkits/echtpost/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/echtpost/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/echtpost/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/echtpost/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/echtpost/framework/crew-ai) ## Connect Echtpost to Claude Cowork ### Connecting Echtpost 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 Echtpost through MCP without you sharing account credentials directly with the agent. ## What is the Echtpost MCP server, and what's possible with it? The Echtpost MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Echtpost account. It provides structured and secure access to your Echtpost templates, so your agent can perform actions like listing available postcard templates, retrieving template details, and preparing for secure document creation on your behalf. - Comprehensive template retrieval: Instantly fetch all available postcard and document templates in your Echtpost account for quick reference and selection. - Detailed template information: Allow your agent to access template names, descriptions, preview links, types, and creation timestamps to help you make informed decisions before sending confidential documents. - Template ID lookup for card creation: Let your agent efficiently obtain the necessary template IDs required for creating and dispatching secure postcards or messages. - Preview and validation of design assets: Preview templates visually and validate their suitability—ensuring every document meets your standards before sending. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ECHTPOST_LIST_TEMPLATES` | List templates | This tool retrieves a list of all available templates in the Echtpost account. Templates serve as the base design for postcards and are essential for creating cards. The action operates independently using only an authentication token and returns detailed template information including id, name, description, preview URL, type, and creation time. This action is crucial for viewing templates before creating cards and obtaining the necessary template IDs for subsequent actions. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Echtpost MCP server connects Claude Cowork to your Echtpost account through Composio. Once connected, Cowork can use the available Echtpost tools and triggers to complete tasks on your behalf. ## Complete Code None listed. ## How to build Echtpost MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/echtpost/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/echtpost/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/echtpost/framework/claude-code) - [Codex](https://composio.dev/toolkits/echtpost/framework/codex) - [OpenClaw](https://composio.dev/toolkits/echtpost/framework/openclaw) - [Hermes](https://composio.dev/toolkits/echtpost/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/echtpost/framework/cli) - [Google ADK](https://composio.dev/toolkits/echtpost/framework/google-adk) - [LangChain](https://composio.dev/toolkits/echtpost/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/echtpost/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/echtpost/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/echtpost/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/echtpost/framework/crew-ai) ## Related Toolkits - [Gmail](https://composio.dev/toolkits/gmail) - Gmail is Google's email service with powerful spam protection, search, and G Suite integration.

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