This guide explains the easiest and most robust way to connect your Customerio account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either. ## 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) - [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 ### What is Composio Connect? Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can: - Search and load tools from relevant toolkits on-demand, reducing context usage. - Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM. - Manage app authentication end-to-end with zero manual overhead. ## Connect Customerio to Hermes ### Integrating Customerio with Hermes ### Using Composio Connect CLI 1. Install the Composio CLI Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you. ```bash curl -fsSL https://composio.dev/install | bash ``` ## 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_CUSTOMER_IO_SUPPRESS_PERSON` | Suppress Customer Profile | Tool to suppress a person. use when you need to permanently delete a customer's profile and prevent them from being re-added. | | `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 | Tool to retrieve details about a specific trigger. use after triggering a broadcast to confirm its status and metadata. | | `CUSTOMERIO_GET_TRIGGERS` | Get Triggers | Tool to retrieve a list of triggers for a specific broadcast. use after identifying broadcast id to inspect associated triggers. | | `CUSTOMERIO_GET_WEBHOOKS` | Get Customer.io Workspace Webhooks | Tool to retrieve a list of webhooks. use after setting up reporting webhooks to fetch current webhook configurations in your workspace. | | `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_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 | Tool to list all transactional message templates. use when you need to fetch available transactional messages. | | `CUSTOMERIO_TRIGGER_BROADCAST` | Trigger Broadcast | Tool to manually trigger a broadcast. use when you need to override the default audience and provide personalization data after confirming the broadcast id. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Customerio MCP server provides comprehensive access to Customerio operations through Composio. Once connected, Hermes can perform all major Customerio actions on your behalf using natural language commands. ## Complete Code None listed. ## Conclusion ### Way Forward With Customerio connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to. From here, you can extend Hermes further: - Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you. - Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft. - Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

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 Hermes? Yes, you can. Hermes 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)
