In this guide, I will explain the easiest and most secure way to connect your CapSolver account to ChatGPT via Composio Connect, so it can create CAPTCHA tasks, poll for solutions, check your balance, and submit solution feedback through natural language commands without ever putting your account credentials at risk. ## Also integrate CapSolver with - [Claude Cowork](https://composio.dev/toolkits/capsolver/framework/claude-cowork) - [Hermes](https://composio.dev/toolkits/capsolver/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/capsolver/framework/atomic-agent) ## TL;DR ### Why use Composio over default connectors? - Apps with read and write access. Default connectors mostly can read your data. Composio's CapSolver integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more. - 1,500+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce. - One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app. - Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand. - Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation. ## Connect CapSolver to ChatGPT ### Prerequisites - A ChatGPT account. We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), and the steps are the same on the web. - Access to the CapSolver workspace you want to connect. - [Composio plugin](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt). Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account. ### Step-by-step: Connect CapSolver to ChatGPT ### 1. Install the Composio plugin Click the button. ChatGPT opens the Composio plugin page. Click Install plugin. [Install in ChatGPT](https://chatgpt.com/plugins/plugin_asdk_app_6a58503580c08191b78cc5bdaf4eba6e) You can also find it inside ChatGPT: go to Settings, open Plugins, search the marketplace for Composio, and click Install plugin. ### 2. Authenticate After you install, ChatGPT asks you to authenticate with Composio. Log in and click Allow access to authorize ChatGPT to use your Composio account. ### 3. Start using Composio That is it. Composio tools are now available in ChatGPT. Type @Composio followed by your request, for example @Composio find unread CapSolver messages and summarize them, and it will run the actions you authorize. On first use it asks you to authorize CapSolver. ### Option 2: Add Composio as an MCP server If you cannot use the plugin marketplace, add Composio as a custom MCP server instead. ### 1. Open the MCP settings In ChatGPT, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab. ### 2. Add the server Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is the CapSolver MCP server, and what's possible with it? The CapSolver MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your CapSolver account. It provides structured and secure access to CAPTCHA recognition and token-solving workflows, so your agent can solve supported CAPTCHA challenges, recognize text from images, check task results and balances, and submit solution feedback on your behalf. - Solve supported CAPTCHA challenges: Have your agent solve reCAPTCHA, Cloudflare Turnstile, Cloudflare Challenge, AWS WAF, GeeTest, MTCaptcha, DataDome, and BotDeflector challenges. - Track asynchronous solutions: Let the agent wait for and retrieve CAPTCHA task results, with bounded polling for supported workflows. - Recognize CAPTCHA images: Direct your agent to classify AWS WAF or reCAPTCHA v2 images, recognize image text, or run supported vision modules for points, distances, angles, rectangles, and text. - Monitor usage and report outcomes: Instruct your agent to check the CapSolver balance and submit feedback when a previously returned solution token worked or failed. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CAPSOLVER_CLASSIFY_AWS_WAF` | Classify AWS WAF Image | Classify one AWS WAF challenge image or a nine-image grid and return the immediate geometric or object result.

With a standalone CapSolver MCP server, the agents and LLMs can only access a fixed set of CapSolver tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from CapSolver and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with ChatGPT? Yes, you can. ChatGPT 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 CapSolver tools. ### Can I manage the permissions and scopes for CapSolver while using Tool Router? Yes, absolutely. You can configure which CapSolver 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 CapSolver data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
