# How to connect Simplero to Claude ```json { "title": "How to connect Simplero to Claude", "toolkit": "Simplero", "toolkit_slug": "simplero", "framework": "Claude Cowork", "framework_slug": "claude-cowork", "url": "https://composio.dev/toolkits/simplero/framework/claude-cowork", "markdown_url": "https://composio.dev/toolkits/simplero/framework/claude-cowork.md", "updated_at": "2026-10-04T14:11:49.100Z" } ``` ## Introduction Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf. This guide walks you through the easiest and most secure way to connect your Simplero account to Claude via Composio Connect, enabling it to list all active contacts in Simplero, send a broadcast email to your list, enroll a user in a specific course, and more such actions on your behalf without compromising your account security. Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three. ## Also integrate Simplero with - [Claude Code](https://composio.dev/toolkits/simplero/framework/claude-code) - [OpenAI Agents SDK](https://composio.dev/toolkits/simplero/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/simplero/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/simplero/framework/codex) - [OpenClaw](https://composio.dev/toolkits/simplero/framework/openclaw) - [Hermes](https://composio.dev/toolkits/simplero/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/simplero/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/simplero/framework/google-adk) - [LangChain](https://composio.dev/toolkits/simplero/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/simplero/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/simplero/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/simplero/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/simplero/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/simplero/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/simplero/framework/autogen) ## Connect Simplero to Claude Cowork ### Connecting Simplero to Claude Web, Desktop, and Cowork Two ways to add the Composio connector. Pick whichever you prefer. ### 1. Add with one click Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2. [Add to Claude](https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Composio&connectorUrl=https%3A%2F%2Fconnect.composio.dev%2Fmcp) ### Add manually In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top. Click Add custom connector and paste in the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is the Simplero MCP server, and what's possible with it? The Simplero MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Simplero account. It provides structured and secure access to your contacts, mailing lists, subscriptions, products, and administrators, so your agent can manage contacts, organize tags, handle list subscriptions, review products, and manage administrators on your behalf. - Contact management: Have your agent find contacts by email, retrieve their details, create new contacts, update existing records, and change contact names or login emails. - Contact tagging: Let the agent add or remove tags for contacts by email to keep your audience organized. - Mailing list subscriptions: Direct your agent to view your mailing lists, check a contact's subscriptions, and subscribe or unsubscribe customers from a chosen list. - Product discovery: Instruct your agent to list the products available in your Simplero account for quick reference. - Administrator management: Have your agent review administrators and available roles, create or update administrator access, and remove administrators when needed. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `SIMPLERO_ADD_TAG_TO_CONTACT` | Add Tag to Contact | Tool to add a tag to a contact identified by email address.

Why does Claude not use the Composio connector for Simplero? The connector can show as connected, but Claude must use it in each Simplero conversation. - Click + at the lower left of the chat, or type /. - Hover Connectors. - Turn on Composio. - Ask Claude to connect to Simplero again. ### 2. Why does Claude show an MCP server error before Simplero connects? Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Simplero. - Check that the connector URL is https://connect.composio.dev/mcp. - Connectors run from Anthropic's cloud, so your device network is usually not the problem. - Add the connector again from Customize > Connectors, then ask Claude to connect Simplero. - If it fails again, send the error and the ofid_ reference id to support@composio.dev. ### 3. Why does the Simplero authorization link not work? The Composio connector is one server. Your Simplero account connects separately when Claude asks for it. - If the browser does not open, or the link expires, ask Claude to retry the Simplero connection. - Composio creates a fresh Simplero authorization link. - Open that link in your browser and finish the Simplero sign-in. ### 4. Why do Simplero actions fail after they worked before? The Simplero connection can expire or lose permission. - Ask Claude to inspect the Simplero connection. - If the connection is unhealthy, disconnect it when Claude prompts you. - Reconnect the Simplero account and retry the action. - If Claude shows a permission prompt, approve it before Claude changes data in Simplero. - If the action still fails with a permission error, check that the connected account has that permission in Simplero itself. ### 5. How do I switch to a different Simplero account? Claude can manage the Simplero connection for you. - Ask Claude to disconnect or delete the current Simplero account. - Ask Claude to connect Simplero again. - Open the new Composio authorization link for Simplero. - Sign in with the other Simplero account in the browser. - After the account connects, ask Claude to retry the Simplero task. ### 6. Why is my Simplero connection missing in Claude Desktop or on a Team plan? The connector belongs to your Claude account, so your Simplero connection works in Claude Web, Desktop, and Cowork. - In Claude Desktop, open Customize > Connectors. - Next to Composio, click ⋮ and click Clear cache. - If Simplero tools still do not appear, click ⋮, disconnect, remove the connector, and add it again. - On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Simplero. ## Creating MCP Server - Stand-alone vs Composio SDK The Simplero MCP server connects Claude Web, Desktop, and Cowork to your Simplero account through Composio. Once connected, Claude can use the available Simplero tools and triggers to complete tasks on your behalf. ## Complete Code None listed. ## How to build Simplero MCP Agent with another framework - [Claude Code](https://composio.dev/toolkits/simplero/framework/claude-code) - [OpenAI Agents SDK](https://composio.dev/toolkits/simplero/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/simplero/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/simplero/framework/codex) - [OpenClaw](https://composio.dev/toolkits/simplero/framework/openclaw) - [Hermes](https://composio.dev/toolkits/simplero/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/simplero/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/simplero/framework/google-adk) - [LangChain](https://composio.dev/toolkits/simplero/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/simplero/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/simplero/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/simplero/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/simplero/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/simplero/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/simplero/framework/autogen) ## Related Toolkits - [Reddit](https://composio.dev/toolkits/reddit) - Reddit is a social news platform with thriving user-driven communities (subreddits).

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