This guide explains the easiest and most robust way to connect your Mailbluster 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 Mailbluster with - [OpenAI Agents SDK](https://composio.dev/toolkits/mailbluster/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/mailbluster/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/mailbluster/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/mailbluster/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/mailbluster/framework/codex) - [OpenClaw](https://composio.dev/toolkits/mailbluster/framework/openclaw) - [CLI](https://composio.dev/toolkits/mailbluster/framework/cli) - [Google ADK](https://composio.dev/toolkits/mailbluster/framework/google-adk) - [LangChain](https://composio.dev/toolkits/mailbluster/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/mailbluster/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/mailbluster/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/mailbluster/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/mailbluster/framework/crew-ai) ## TL;DR ### What is Composio Connect?

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