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 Cats account to Claude via Composio Connect, enabling it to show me five random cat images, list popular cat breeds with photos, find unique cat facts for trivia, 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 Cats with - [Claude Code](https://composio.dev/toolkits/cats/framework/claude-code) - [OpenAI Agents SDK](https://composio.dev/toolkits/cats/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/cats/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/cats/framework/codex) - [OpenClaw](https://composio.dev/toolkits/cats/framework/openclaw) - [Hermes](https://composio.dev/toolkits/cats/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/cats/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/cats/framework/google-adk) - [LangChain](https://composio.dev/toolkits/cats/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/cats/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/cats/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/cats/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/cats/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/cats/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/cats/framework/autogen) ## Connect Cats to Claude Cowork ### Connecting Cats 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 Cats MCP server, and what's possible with it? The Cats MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Cats account. It provides structured and secure access to a wide collection of cat images, breed information, and fun feline facts, so your agent can fetch cat data, browse curated cat images, and pull breed details on your behalf. - Portals listing for cat resources: Instruct your agent to list and browse all available cat-related portals, making it easy to explore organized collections of cat images and data. - Metadata exploration with pagination: Have your agent efficiently page through vast cat collections, ensuring you can access just the right portal or dataset without missing a thing. - On-demand cat image discovery: Let your agent find and retrieve high-quality cat images from the API’s large, curated library—perfect for enrichment or just a dose of cuteness. - Access to detailed breed and fact data: Ask your agent to pull up detailed info on cat breeds and fun facts, making it a handy assistant for both research and entertainment. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CATS_CREATE_FAVOURITE` | Create Favourite | Tool to save an image as a favourite to your account.

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

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