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 Api labz account to Claude via Composio Connect, enabling it to validate this IBAN before making payment, add a new deal record to CRM, list all Airtable tables in your project base, 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 Api labz with - [Claude Code](https://composio.dev/toolkits/api_labz/framework/claude-code) - [OpenAI Agents SDK](https://composio.dev/toolkits/api_labz/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/api_labz/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/api_labz/framework/codex) - [OpenClaw](https://composio.dev/toolkits/api_labz/framework/openclaw) - [Hermes](https://composio.dev/toolkits/api_labz/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/api_labz/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/api_labz/framework/google-adk) - [LangChain](https://composio.dev/toolkits/api_labz/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/api_labz/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/api_labz/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/api_labz/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/api_labz/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/api_labz/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/api_labz/framework/autogen) ## Connect Api labz to Claude Cowork ### Connecting Api labz 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 Api labz MCP server, and what's possible with it? The API Labz MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your API Labz account. It provides structured and secure access to IBAN validation, deal integration, Airtable table listings, and Trello card search, so your agent can validate bank account numbers, integrate deals, list Airtable tables, and find relevant Trello cards on your behalf. - IBAN validation: Have your agent validate International Bank Account Numbers before using them in financial workflows. - Deal integration: Direct your agent to add deals to API Labz as part of your sales workflow. - Airtable table discovery: Let the agent list the tables available in a chosen Airtable base. - Trello card search: Instruct your agent to use semantic search to find relevant Trello cards across boards and lists. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `API_LABZ_IBAN_VALIDATOR` | Validate IBAN | Tool to validate International Bank Account Numbers (IBANs). Use when you need to verify an IBAN's structure before processing transactions. | | `API_LABZ_INTEGRATE_DEAL` | Integrate Deal | Tool to integrate a deal into API Labz. Use when you need to push a new or updated deal record into the system after preparing required fields. | | `API_LABZ_LIST_TABLES` | List Airtable Tables | Tool to list all Airtable tables for a given base. Use when you need to retrieve table names before interacting with a table. | | `API_LABZ_TRELLO_AI_SEARCH_ENGINE` | Trello AI Search Engine | AI-powered semantic search tool for Trello cards across boards and lists. Use this when you need to: - Find cards by natural language queries (e.g., "bug reports from last week") - Search across multiple Trello boards or within a specific board/list - Locate cards containing specific keywords, topics, or concepts - Discover relevant cards without knowing exact titles Returns matching cards with IDs, titles, descriptions, and direct URLs for easy access. | ## Supported Triggers None listed. ## Troubleshooting ### 1. Why does Claude not use the Composio connector for Api labz? The connector can show as connected, but Claude must use it in each Api labz conversation. - Click + at the lower left of the chat, or type /. - Hover Connectors. - Turn on Composio. - Ask Claude to connect to Api labz again. ### 2. Why does Claude show an MCP server error before Api labz connects? Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Api labz. - 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 Api labz. - If it fails again, send the error and the ofid_ reference id to support@composio.dev. ### 3. Why does the Api labz authorization link not work? The Composio connector is one server. Your Api labz account connects separately when Claude asks for it. - If the browser does not open, or the link expires, ask Claude to retry the Api labz connection. - Composio creates a fresh Api labz authorization link. - Open that link in your browser and finish the Api labz sign-in. ### 4. Why do Api labz actions fail after they worked before? The Api labz connection can expire or lose permission. - Ask Claude to inspect the Api labz connection. - If the connection is unhealthy, disconnect it when Claude prompts you. - Reconnect the Api labz account and retry the action. - If Claude shows a permission prompt, approve it before Claude changes data in Api labz. - If the action still fails with a permission error, check that the connected account has that permission in Api labz itself. ### 5. How do I switch to a different Api labz account? Claude can manage the Api labz connection for you. - Ask Claude to disconnect or delete the current Api labz account. - Ask Claude to connect Api labz again. - Open the new Composio authorization link for Api labz. - Sign in with the other Api labz account in the browser. - After the account connects, ask Claude to retry the Api labz task. ### 6. Why is my Api labz connection missing in Claude Desktop or on a Team plan? The connector belongs to your Claude account, so your Api labz connection works in Claude Web, Desktop, and Cowork. - In Claude Desktop, open Customize > Connectors. - Next to Composio, click ⋮ and click Clear cache. - If Api labz 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 Api labz. ## Creating MCP Server - Stand-alone vs Composio SDK The Api labz MCP server connects Claude Web, Desktop, and Cowork to your Api labz account through Composio. Once connected, Claude can use the available Api labz tools and triggers to complete tasks on your behalf. ## Complete Code None listed. ## How to build Api labz MCP Agent with another framework - [Claude Code](https://composio.dev/toolkits/api_labz/framework/claude-code) - [OpenAI Agents SDK](https://composio.dev/toolkits/api_labz/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/api_labz/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/api_labz/framework/codex) - [OpenClaw](https://composio.dev/toolkits/api_labz/framework/openclaw) - [Hermes](https://composio.dev/toolkits/api_labz/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/api_labz/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/api_labz/framework/google-adk) - [LangChain](https://composio.dev/toolkits/api_labz/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/api_labz/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/api_labz/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/api_labz/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/api_labz/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/api_labz/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/api_labz/framework/autogen) ## Related Toolkits - [Composio](https://composio.dev/toolkits/composio) - Composio is an integration platform that connects AI agents with hundreds of business tools.

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