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 Exist account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Exist with - [OpenAI Agents SDK](https://composio.dev/toolkits/exist/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/exist/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/exist/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/exist/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/exist/framework/codex) - [OpenClaw](https://composio.dev/toolkits/exist/framework/openclaw) - [Hermes](https://composio.dev/toolkits/exist/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/exist/framework/google-adk) - [LangChain](https://composio.dev/toolkits/exist/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/exist/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/exist/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/exist/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/exist/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/exist/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/exist/framework/autogen) ## TL;DR ### How Atomic Agent connects to Exist 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 Exist to Atomic Agent ### Connect Exist 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 Exist. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Exist 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 Exist MCP server, and what's possible with it? The Exist MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Exist account. It provides structured and secure access to your personal analytics data, so your agent can perform actions like analyzing correlations, retrieving user attributes, exploring supported metrics, and inspecting your profile on your behalf. - Personal profile access and insights: Instantly retrieve and review your Exist user profile, including preferences and account settings, to keep your agent aware of your context. - Attribute exploration and discovery: Browse and list all available attribute templates or user attributes, making it easy to understand what metrics you can track, analyze, or visualize. - Correlation analysis: Ask your agent to fetch and explore recent correlations between tracked attributes—like how weather or sleep might relate to your mood or productivity. - Custom analytics setup: Let your agent help you discover and understand supported attribute templates before you start tracking or updating new data points. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `EXIST_ACQUIRE_ATTRIBUTE_OWNERSHIP` | Acquire Attribute Ownership | Tool to acquire ownership of attributes for the authenticated user. Allows your service to write data to these attributes. Use when you need to create or take ownership of attributes before writing data. Acquiring a templated attribute the user doesn't have yet will create this attribute and give you ownership. | | `EXIST_GET_ATTRIBUTES_WITH_VALUES` | Get Attributes With Values | Tool to retrieve attributes with their current values for the authenticated user. Use when you need both attribute metadata and their historical values. Results are limited to your read scopes. | | `EXIST_GET_ATTRIBUTE_TEMPLATES` | Get Attribute Templates | Tool to retrieve a paged list of supported attribute templates. Use when you need to browse available templates before creating or updating data. | | `EXIST_GET_AVERAGES` | Get Averages | Tool to retrieve the most recent average values for each tracked attribute, with one set per week. Returns overall weekly averages plus daily breakdowns (Monday-Sunday). Use include_historical flag to retrieve historical average records. | | `EXIST_GET_CORRELATIONS` | Get Correlations | Retrieve a paginated list of correlations discovered between tracked attributes in the last week. Correlations reveal statistical relationships between different metrics (e.g., sleep duration vs mood). Filter by relationship strength, confidence level (statistical significance), or specific attributes. Returns correlation coefficients, p-values, and human-readable descriptions. | | `EXIST_GET_INSIGHTS` | Get Insights | Tool to retrieve automatically-generated insights about patterns in tracked data for the authenticated user. Insights are observations about correlations, trends, and anomalies (e.g., "You walked more on days you slept well"). Use when analyzing user behavior patterns or displaying personalized feedback. | | `EXIST_GET_OWNED_ATTRIBUTES` | Get Owned Attributes | Tool to retrieve attributes owned by your service for the authenticated user. Use when you need to limit data updates to only the attributes your service controls. | | `EXIST_GET_USER_ATTRIBUTES` | Get User Attributes | Tool to retrieve a paged list of the user's attributes without values. Use when you need metadata on available attributes for filtering or selection. Omitting `groups` and `attributes` filters returns the full attribute catalog; use those filters to narrow results and avoid oversized responses. | | `EXIST_EXIST_GET_USER_PROFILE` | Get User Profile | Tool to retrieve the authenticated user's profile details and preferences. Use after authentication to inspect account settings and status. OAuth scopes granted during authentication determine which fields are returned; missing fields indicate insufficient scopes. Response includes a timezone field; use it when interpreting any date-based attributes. | | `EXIST_INCREMENT_ATTRIBUTE_VALUES` | Increment Attribute Values | Tool to increment attribute values by a delta amount rather than setting totals. Use for counters and cumulative data. Does not work with string, scale, or time of day attributes. | | `EXIST_EXIST_OAUTH2_AUTHORIZE` | Exist OAuth2 Authorize | Constructs an OAuth2 authorization URL for Exist.io. This tool generates the URL that users must visit in their browser to grant permissions to your application. After user consent, Exist redirects back to your redirect_uri with an authorization code that can be exchanged for an access token. This action does not make an API call - it only builds the authorization URL. | | `EXIST_RELEASE_ATTRIBUTE_OWNERSHIP` | Release Attribute Ownership | Tool to release ownership of attributes for the authenticated user. Use when your service will stop providing data for an attribute or becomes inactive. | ## Supported Triggers None listed. ## Troubleshooting ### Why is my API key rejected? 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 Exist from Atomic Agent With your account connected, ask Atomic Agent to work with Exist in natural language. You can connect more apps through the same Composio integration as you need them.

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