This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Endorsal account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Endorsal with - [OpenAI Agents SDK](https://composio.dev/toolkits/endorsal/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/endorsal/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/endorsal/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/endorsal/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/endorsal/framework/codex) - [OpenClaw](https://composio.dev/toolkits/endorsal/framework/openclaw) - [Hermes](https://composio.dev/toolkits/endorsal/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/endorsal/framework/google-adk) - [LangChain](https://composio.dev/toolkits/endorsal/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/endorsal/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/endorsal/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/endorsal/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/endorsal/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/endorsal/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/endorsal/framework/autogen) ## TL;DR ### How Atomic Agent connects to Endorsal Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Endorsal to Atomic Agent ### Connect Endorsal to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Endorsal. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Endorsal account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## What is the Endorsal MCP server, and what's possible with it? The Endorsal MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Endorsal account. It provides structured and secure access to your testimonials, contacts, and campaign data, so your agent can perform actions like collecting new testimonials, managing contacts, organizing campaigns, and displaying review widgets on your behalf. - Automated testimonial collection and submission: Enable your agent to create and submit new customer testimonials directly into your Endorsal account, streamlining the feedback process. - Campaign management and insights: Let your agent retrieve and list all AutoRequest campaigns, check campaign details, and monitor their status to keep your outreach efforts on track. - Contact and testimonial organization: Easily fetch, list, and manage all contacts, as well as pull up all testimonials associated with a specific contact for better relationship tracking. - Widget and property access: Allow your agent to fetch details of specific display widgets and properties, helping you control how testimonials are showcased on your website. - Tag and metadata retrieval: Retrieve tag details and full testimonial metadata, so your agent can help organize, group, or analyze your customer feedback efficiently. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ENDORSAL_ARCHIVE_CONTACT` | Archive Contact | Tool to archive a contact using its unique identifier.

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Endorsal from Atomic Agent With your account connected, ask Atomic Agent to work with Endorsal in natural language. You can connect more apps through the same Composio integration as you need them.

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