How to integrate Android Texter MCP with Hermes

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows. This guide explains the easiest and most robust way to connect your Android Texter 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.

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.

Integrating Android Texter 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
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Android Texter

Ask your agent to connect to Android Texter, or simply request any Android Texter-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Android Texter connection.


Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Android Texter or request any Android Texter-related task. It will prompt you to authenticate and authorize access.

5. Done!

What is the Android Texter MCP server, and what's possible with it?

The Android Texter MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Android Texter account. It provides structured and secure access to your text messages, contacts, linked Android devices, and quick replies, so your agent can send SMS and MMS messages, review conversations, check delivery status, find contacts, and manage reusable replies on your behalf.

  • SMS and MMS messaging: Have your agent send a message to one person or deliver the same message to up to 10 recipients through a linked Android device.
  • Message and conversation review: Instruct your agent to list sent or received messages and review your conversation history with a specific phone number.
  • Delivery status checks: Let the agent check whether a sent message is queued, sent, delivered, or failed.
  • Contact and device lookup: Direct your agent to find contacts by name, phone text, or tag, and view linked Android devices and their online status.
  • Reusable quick replies: Have your agent list, create, update, or delete saved quick replies for messages you send often.

Way Forward

With Android Texter 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.

FAQ

Frequently asked questions

With a standalone Android Texter MCP server, the agents and LLMs can only access a fixed set of Android Texter tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Android Texter and many other apps based on the task at hand, all through a single MCP endpoint.

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 Android Texter tools.

Yes, absolutely. You can configure which Android Texter 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.

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 Android Texter data and credentials are handled as safely as possible.
