This guide explains the easiest and most robust way to connect your Postalytics 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 Postalytics with - [OpenAI Agents SDK](https://composio.dev/toolkits/postalytics/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/postalytics/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/postalytics/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/postalytics/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/postalytics/framework/codex) - [OpenClaw](https://composio.dev/toolkits/postalytics/framework/openclaw) - [CLI](https://composio.dev/toolkits/postalytics/framework/cli) - [Google ADK](https://composio.dev/toolkits/postalytics/framework/google-adk) - [LangChain](https://composio.dev/toolkits/postalytics/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/postalytics/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/postalytics/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/postalytics/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/postalytics/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 Postalytics to Hermes ### Integrating Postalytics 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 Postalytics MCP server, and what's possible with it? The Postalytics MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Postalytics account. It provides structured and secure access so your agent can perform Postalytics operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `POSTALYTICS_ADD_ACCOUNT` | Add Account | Tool to create a new sub-account in the Postalytics system.

Once connected, Hermes can perform all major Postalytics actions on your behalf using natural language commands. ## Complete Code None listed. ## Conclusion ### Way Forward With Postalytics 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 Postalytics MCP server, the agents and LLMs can only access a fixed set of Postalytics tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Postalytics 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 Postalytics tools. ### Can I manage the permissions and scopes for Postalytics while using Tool Router? Yes, absolutely. You can configure which Postalytics 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 Postalytics data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
