It treats the AI agent as a first-class teammate, planning, coding, and validating work through an Agent Manager dashboard with deep browser connectivity. In this guide, I will explain the easiest and most secure way to connect your Customerio account to Antigravity IDE via Composio Connect, so it can list all segments in your workspace, get delivery metrics for last week's emails, show all people in VIP customer segment, and more without ever putting your account credentials at risk. ## Also integrate Customerio with - [ChatGPT](https://composio.dev/toolkits/customerio/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/customerio/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/customerio/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/customerio/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/customerio/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/customerio/framework/codex) - [OpenClaw](https://composio.dev/toolkits/customerio/framework/openclaw) - [Hermes](https://composio.dev/toolkits/customerio/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/customerio/framework/cli) - [Google ADK](https://composio.dev/toolkits/customerio/framework/google-adk) - [LangChain](https://composio.dev/toolkits/customerio/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/customerio/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/customerio/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/customerio/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/customerio/framework/crew-ai) ## TL;DR ### Why use Composio? Composio provides: - Access to 1,000+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows. - Programmatic tool calling. Allows LLMs to write code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses. - Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need. ## Connect Customerio to Antigravity ### Connect Customerio to Antigravity Antigravity does not ship with one-click custom MCP install links yet, so configuration goes through the IDE's raw config file. The process takes under a minute. ### 1. Open the MCP Config Go to Antigravity Settings, open the Customizations tab, then click Open MCP Config to open mcp_config.json in the editor. ### 2. Get your API key Go to the [Composio Dashboard](https://dashboard.composio.dev/~/org/connect/clients/) and copy your API key. ### 3. Add Composio to mcp_config.json Paste the following configuration into the file: ```bash { "mcpServers": { "remote-composio": { "serverUrl": "https://connect.composio.dev/mcp", "headers": { "x-consumer-api-key": "your-composio-api-key" } } } } ``` ## What is the Customerio MCP server, and what's possible with it? The Customerio MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Customer.io account. It provides structured and secure access to your customer engagement workspace, allowing your agent to send targeted communications, manage segments, retrieve messaging analytics, and automate customer data management on your behalf. - Targeted message analytics and tracking: Retrieve detailed lists of messages sent, including delivery metrics, to monitor campaign performance and engagement. - Segment discovery and membership management: Let your agent fetch all segments, get details for a specific segment, and list all customers in a segment for precise audience targeting. - Integration and webhook management: Have your agent list and review all integrations and webhooks in your workspace to streamline system connectivity and reporting. - Customer profile suppression: Direct your agent to permanently suppress (delete and block) customer profiles, ensuring compliance and data privacy. - Collection metadata retrieval: Retrieve up-to-date details for all collections in your workspace, keeping your AI-powered workflows and automations in sync with your data sources. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CUSTOMERIO_ADD_PERSON_TO_GROUP` | Add Person to Group | Tool to add people to a group in Customer.io. Groups represent objects like companies, accounts, or projects that people belong to. Use when you need to establish relationships between people and organizational entities. | | `CUSTOMERIO_CREATE_ALIAS` | Create Profile Alias | Tool to create an alias to merge multiple profiles in Customer.io. Use when you need to support multiple identifiers for a single person. The alias operation moves all data from the previous_id profile to the user_id profile, consolidating them into a single canonical profile. | | `CUSTOMERIO_CUSTOMER_IO_SUPPRESS_PERSON` | Suppress Customer Profile | Suppress a customer profile to permanently delete it and prevent re-adding with the same identifier. IMPORTANT: This action requires Track API credentials (Basic Auth with siteId:apiKey), not App API credentials. Suppression also deletes the customer profile - you don't need to call a separate delete endpoint. Use this for GDPR/CCPA compliance requests. The operation is irreversible and prevents any future attempts to re-add a person with the same identifier (email or ID). | | `CUSTOMERIO_GET_INTEGRATIONS` | Get Integrations | Tool to retrieve a list of integrations in your workspace. Use when you need to discover configured integrations. | | `CUSTOMERIO_GET_MESSAGES` | Get Messages | Tool to retrieve a list of messages sent from your workspace. Use when you need paginated delivery metrics for messages, e.g., list email messages delivered between two timestamps. | | `CUSTOMERIO_GET_SEGMENT_DETAILS` | Get Segment Details | Tool to retrieve details of a specific segment. Use after identifying the segment ID from list segments. | | `CUSTOMERIO_GET_SEGMENT_MEMBERSHIP` | Get Segment Membership | Tool to retrieve people in a specific segment. Use when you need to page through segment membership after identifying segment ID. | | `CUSTOMERIO_GET_SEGMENTS` | Get Segments | Tool to retrieve a list of segments in your workspace. Use when you need to fetch all segments after configuring segment rules. | | `CUSTOMERIO_GET_TRIGGER` | Get Trigger | Retrieves details about a specific API-triggered broadcast, including trigger ID, campaign ID, creation timestamp, recipient filter criteria, and personalization data. Use this after triggering a broadcast to verify its configuration and check the data used for message personalization. | | `CUSTOMERIO_GET_TRIGGERS` | Get Broadcast Triggers | Retrieve all API trigger instances for a specific broadcast/campaign. Returns trigger metadata including IDs, creation timestamps, and processing status. Use after triggering a broadcast to list all its trigger executions. | | `CUSTOMERIO_GET_WEBHOOKS` | Get Customer.io Workspace Webhooks | Retrieves all reporting webhook configurations from the Customer.io workspace. Reporting webhooks send event notifications (message sent, opened, clicked, etc.) to your specified endpoints. Use this to list all configured webhooks and their settings including subscribed events, endpoints, and status. Returns an empty list if no webhooks are configured. | | `CUSTOMERIO_IDENTIFY_PERSON` | Identify Person | Tool to identify a person and assign traits to them in Customer.io. Creates a new person profile if it doesn't exist, or updates an existing one. Use when adding new users, updating user profiles, or tracking anonymous visitors. Either user_id or anonymous_id must be provided. | | `CUSTOMERIO_LIST_COLLECTIONS` | List Collections | Tool to list all Collections metadata. Use when you need to retrieve current details of each Collection in your workspace. | | `CUSTOMERIO_LIST_IP_ADDRESSES` | List IP Addresses | Tool to retrieve the list of IP addresses used by Customer.io for sending messages. Use when you need to allowlist or configure firewall rules for Customer.io's sending infrastructure. | | `CUSTOMERIO_LIST_NEWSLETTERS` | List Newsletters | Tool to list all newsletters. Use when paginating through newsletter metadata. | | `CUSTOMERIO_LIST_SNIPPETS` | List Snippets | Tool to list all snippets in your workspace. Use when you need to retrieve all reusable content snippets for templating or dynamic content insertion. | | `CUSTOMERIO_LIST_TRANSACTIONAL_MESSAGES` | List Transactional Messages | Lists all transactional message templates in your Customer.io workspace. Returns the ID and name (trigger name) for each template. Use this when you need to discover available transactional message templates or retrieve their IDs for sending messages via the API. | | `CUSTOMERIO_SEND_BATCH` | Send Batch CDP Calls | Send multiple CDP calls (identify, track, page, screen, group, alias) in a single batch request. Use this to efficiently send multiple events or profile updates in one API call. The batch endpoint supports up to 500KB total with 32KB per individual call. Each call in the batch can be a different type (identify, track, page, screen, group, or alias). Requirements by call type: - identify/track/page/screen: Require userId or anonymousId - group: Requires groupId (and userId or anonymousId) - track: Requires event name - alias: Requires userId and previousId Note: This action uses the CDP API base URL (https://cdp.customer.io/v1) which differs from the Track API base URL used by some other Customer.io actions. | | `CUSTOMERIO_TRACK_EVENT` | Track Event | Tool to send an event associated with a person in Customer.io. Records actions users take, along with properties that describe the action. Use when you need to track user behavior, conversions, or custom events for segmentation and campaigns. | | `CUSTOMERIO_TRACK_PAGE` | Track Page View | Tool to track page view events for website visitors in Customer.io.

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