## Introduction

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 CallOnTheGo 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.

## 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 CallOnTheGo to Hermes

### Integrating CallOnTheGo 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 CallOnTheGo MCP server, and what's possible with it?

The CallOnTheGo MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your CallOnTheGo account. It provides structured and secure access so your agent can perform CallOnTheGo operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CALLONTHEGO_ADD_SUPPRESSION_ENTRY` | Add Suppression Entry | Idempotently add one phone number to the Do-Not-Call list. This change persists indefinitely because the API provides no removal route. |
| `CALLONTHEGO_CANCEL_CAMPAIGN` | Cancel Campaign | Irreversibly cancel a campaign and mark its queued or pending recipients cancelled. This changes the campaign to a terminal state but does not delete its record. |
| `CALLONTHEGO_CREATE_CALLER_ID` | Create Caller ID | Add a caller ID and initiate a telecom-provider verification call to confirm ownership. Returns the caller-ID resource ID and verification code needed to complete verification; this does not launch a campaign. |
| `CALLONTHEGO_CREATE_CAMPAIGN` | Create Campaign | Create a draft Voice AI campaign from explicit caller ID, contact list, and audio resources. This only saves a draft: it does not launch the campaign, place or queue calls, or incur call charges. Use the separate launch action when calling should begin. |
| `CALLONTHEGO_DELETE_CALLER_ID` | Delete Caller ID | Permanently remove an owned caller ID configuration. |
| `CALLONTHEGO_DELETE_PHONE_NUMBER` | Delete Phone Number | Permanently remove an owned phone-number configuration by ID; deleting a missing ID also reports success. |
| `CALLONTHEGO_GET_CAMPAIGN` | Get Campaign | Get one campaign's configuration, lifecycle state, resource names, delivery metrics, and cost metrics. |
| `CALLONTHEGO_GET_DASHBOARD_STATS` | Get Dashboard Stats | Return account-level call, contact, group, list, success-rate, and recent-activity summary metrics. |
| `CALLONTHEGO_GET_VOICE_READINESS` | Get Voice Readiness | Return runtime readiness, telecom provider assignment, and supported capabilities for diagnosing whether voice campaigns can run. |
| `CALLONTHEGO_LAUNCH_CAMPAIGN` | Launch Campaign | Validate compliance, provision telecom isolation if needed, and launch a campaign. Launching immediately queues eligible recipients for calls and may incur call charges. |
| `CALLONTHEGO_LIST_AUDIO_ASSETS` | List Audio Assets | List campaign audio assets with playback, duration, transcript, and compliance details. |
| `CALLONTHEGO_LIST_CALLER_IDS` | List Caller IDs | List owned caller IDs with ownership-verification status and inbound-campaign assignment. |
| `CALLONTHEGO_LIST_CALLS` | List Calls | Return one page of account call records for outcome and duration review, with an opaque cursor for the next page. |
| `CALLONTHEGO_LIST_CAMPAIGN_EVENTS` | List Campaign Events | List only the newest 100 delivery events for a campaign, ordered newest first. CallOnTheGo provides no cursor or continuation mechanism, so events older than this fixed window cannot be retrieved with this tool. |
| `CALLONTHEGO_LIST_CAMPAIGN_RECIPIENTS` | List Campaign Recipients | List all recipients for a campaign with call status, attempts, machine detection, and cost estimates. CallOnTheGo does not paginate this endpoint, so campaigns with many recipients can return a large response. |
| `CALLONTHEGO_LIST_CAMPAIGNS` | List Campaigns | List Voice AI campaigns with lifecycle state, linked resources, calling window, rate, estimated cost, compliance state, and timestamps. |
| `CALLONTHEGO_LIST_CONTACT_LISTS` | List Contact Lists | List campaign contact lists with valid, invalid, suppressed, and total recipient counts. |
| `CALLONTHEGO_LIST_CONTACTS` | List Contacts | Return one page of contacts from the connected CallOnTheGo account for CRM lookup, with an opaque cursor for the next page. |
| `CALLONTHEGO_LIST_PHONE_NUMBERS` | List Phone Numbers | List phone numbers owned by the connected CallOnTheGo account, including the resource records needed to identify numbers for later management. |
| `CALLONTHEGO_LIST_SUPPRESSION_ENTRIES` | List Suppression Entries | List Do-Not-Call suppression entries for the connected account. |
| `CALLONTHEGO_PAUSE_CAMPAIGN` | Pause Campaign | Pause a running campaign while retaining its pending recipients for a later resume. The campaign must currently be running. |
| `CALLONTHEGO_QUEUE_CAMPAIGN_LEAD` | Queue Campaign Lead | Queue one phone-number lead for dialing by a running campaign. This can place a call and incur charges; suppressed or already-active leads may return without a new dial. |
| `CALLONTHEGO_RESUME_CAMPAIGN` | Resume Campaign | Resume a paused campaign and immediately requeue its pending recipients for calls. Resuming can place calls and incur call charges. |
| `CALLONTHEGO_SET_CALLER_ID_INBOUND_CAMPAIGN` | Set Caller ID Inbound Campaign | Set or clear the preferred inbound campaign assigned to an owned caller ID. |
| `CALLONTHEGO_UPDATE_CAMPAIGN` | Update Campaign | Update selected configuration fields on a draft or paused campaign. Running, completed, cancelled, and failed campaigns reject updates. Only explicitly supplied fields are changed. |
| `CALLONTHEGO_UPLOAD_AUDIO_ASSET` | Upload Audio Asset | Upload an MP3 or WAV file as a reusable campaign audio asset. This creates stored account data but does not place calls; the API provides no route to delete the stored asset. |
| `CALLONTHEGO_UPLOAD_CONTACT_LIST` | Upload Contact List | Create a campaign contact list from a CSV file. CallOnTheGo normalizes phone numbers, removes duplicates, filters suppressed recipients, and persists the resulting contacts without placing calls. The API provides no route to delete the resulting contact list. |
| `CALLONTHEGO_UPLOAD_SUPPRESSION_CSV` | Upload Suppression CSV | Persistently add many phone numbers to the Do-Not-Call list from a CSV file. Duplicate entries are skipped. This bulk change cannot be undone through the API because no suppression-removal route is available. |
| `CALLONTHEGO_VERIFY_CALLER_ID` | Verify Caller ID | Submit an ownership-verification code for an existing caller ID and return whether it became verified or remains pending. |

## Conclusion

### Way Forward
With CallOnTheGo 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.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and CallOnTheGo MCP?

With a standalone CallOnTheGo MCP server, the agents and LLMs can only access a fixed set of CallOnTheGo tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from CallOnTheGo 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 CallOnTheGo tools.

### Can I manage the permissions and scopes for CallOnTheGo while using Tool Router?

Yes, absolutely. You can configure which CallOnTheGo 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 CallOnTheGo data and credentials are handled as safely as possible.
