## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including CleverReach.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a CleverReach account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## Also integrate CleverReach with

- [ChatGPT](https://composio.dev/toolkits/cleverreach/framework/chatgpt)
- [Claude Cowork](https://composio.dev/toolkits/cleverreach/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/cleverreach/framework/hermes-agent)

## TL;DR

### How Atomic Agent connects to CleverReach
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect CleverReach to Atomic Agent

### Connect CleverReach to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in CleverReach. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your CleverReach account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## What is the CleverReach MCP server, and what's possible with it?

The CleverReach MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your CleverReach account. It provides structured and secure access to your subscriber groups, email campaigns, reports, forms, and marketing data, so your agent can manage subscribers, organize audiences, create campaign content, review performance, and maintain email lists on your behalf.
- Subscriber and group management: Have your agent create, update, bulk upsert, clone, tag, filter, and delete subscribers across CleverReach groups.
- Audience segmentation: Let the agent create reusable filters, find subscribers that match specific rules, count contacts by tags, and review group statistics.
- Campaign and content creation: Direct your agent to create mailing campaigns, reusable mailing templates, and reusable content items for your CleverReach marketing work.
- Marketing performance and records: Instruct your agent to retrieve campaign details, group statistics, filter metrics, receiver events, and subscriber order history.
- List protection and signup forms: Have your agent check, add, or remove blacklist entries and retrieve embeddable HTML, JavaScript, and CSS for existing CleverReach forms.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CLEVERREACH_ADD_BLACKLIST_ENTRIES` | Add Blacklist Entries | Add email addresses to the account-wide CleverReach blacklist in one provider batch request. |
| `CLEVERREACH_ADD_BLACKLIST_ENTRY` | Add Blacklist Entry | Add one email address to the global blacklist when group_id is omitted, or to a group-specific blacklist when it is supplied. Comments are supported only for global entries. |
| `CLEVERREACH_ADD_GROUP_RECEIVER_TAGS` | Add Group Receiver Tags | IRREVERSIBLE AUTOMATION WARNING: add tags to one receiver through a specific group route. This can trigger THEA automation whose resulting effects cannot be undone by removing the tags. |
| `CLEVERREACH_ADD_RECEIVER_TAGS` | Add Receiver Tags | Add tags to one receiver through the account-wide receiver route. This action does not use a group route and does not trigger group-specific THEA automation. |
| `CLEVERREACH_BULK_UPDATE_RECEIVERS` | Bulk Update Receivers | Update existing receivers in one provider batch for a group. Carefully use lifecycle timestamps: nonzero deactivated makes a receiver inactive and zero can reactivate it. The plus variant applies relative numeric attributes and tag removals. Source is not changed for existing receivers. CleverReach does not document whether this batch is atomic. |
| `CLEVERREACH_BULK_UPSERT_RECEIVERS` | Bulk Upsert Receivers | Create or update receivers in one provider batch for a group. Omitting registered, activated, and deactivated activates a new receiver; a nonzero deactivated value makes it inactive, while zero can reactivate it. The plus variant also applies relative numeric attributes and tag removals. CleverReach does not change source when upserting an existing receiver or document whether this batch is atomic. |
| `CLEVERREACH_CHANGE_RECEIVER_EMAIL` | Change Receiver Email | Change one receiver's email address. If overwrite is true and the new email already belongs to another receiver, that existing receiver can be replaced. |
| `CLEVERREACH_CLONE_RECEIVER` | Clone Receiver | Copy a receiver to a target group under a new email address. If overwrite is true and that email already exists, its receiver data can be replaced. |
| `CLEVERREACH_COUNT_RECEIVERS_BY_TAGS` | Count Receivers By Tags | Count receivers with one tag using a GET query, or with a tag constellation using a read-like POST. This action changes no receiver data. |
| `CLEVERREACH_CREATE_ATTRIBUTE` | Create Attribute | Create a global or group-local CleverReach receiver attribute. |
| `CLEVERREACH_CREATE_FILTER` | Create Filter | Create a reusable CleverReach filter or segment in one receiver group. |
| `CLEVERREACH_CREATE_GROUP` | Create Group | Create a CleverReach receiver group and return its group ID for subsequent subscriber operations. |
| `CLEVERREACH_CREATE_MAILING` | Create Mailing | Create a CleverReach mailing campaign definition. This action does not send the campaign, and CleverReach may confirm creation without returning its ID. |
| `CLEVERREACH_CREATE_MAILING_TEMPLATE` | Create Mailing Template | Create a reusable CleverReach mailing template. CleverReach exposes no matching template-delete operation, so this creation is not reversible through this toolkit. |
| `CLEVERREACH_CREATE_MY_CONTENT` | Create My Content | Create a reusable CleverReach "My Content" item that references a URL. Use Delete My Content with the returned or discovered ID to remove it. |
| `CLEVERREACH_CREATE_RECEIVER` | Create Receiver | Create a subscriber in one CleverReach group. If lifecycle timestamps are omitted, CleverReach activates the receiver without sending double opt-in mail; the create response may briefly report the receiver as inactive. Optional group/global attributes, tags, and order history can be supplied at creation. |
| `CLEVERREACH_CREATE_RECEIVER_EVENT` | Create Receiver Event | IRREVERSIBLE: permanently add an event to one CleverReach receiver. CleverReach provides no event deletion endpoint, so this action cannot undo or remove it. |
| `CLEVERREACH_CREATE_RECEIVER_ORDER` | Create Receiver Order | MUTATES ORDER HISTORY: add an order to one CleverReach receiver globally or within a group. Use a unique order_id and verify before retrying. |
| `CLEVERREACH_CREATE_RECEIVERS` | Create Receivers | Create up to 50 subscribers in one CleverReach group and return a separate success or failure result for each receiver. The batch is not atomic. When lifecycle timestamps are omitted, CleverReach activates each receiver without sending double opt-in mail, though create results may briefly show inactive. Each receiver may include attributes, tags, and order history. |
| `CLEVERREACH_DELETE_ATTRIBUTE` | Delete Attribute | Permanently delete a CleverReach global or group-local attribute. This cannot be undone. CleverReach does not verify how the attribute was created; the caller must confirm the selected attribute is safe to delete. |
| `CLEVERREACH_DELETE_BLACKLIST_ENTRIES` | Delete Blacklist Entries | Permanently delete 1-50 exact email addresses sequentially from the global account blacklist, or only from one group's blacklist when group_id is supplied. This is bounded local orchestration over singular deletion endpoints, not a provider bulk operation and not atomic: successful deletions are not rolled back. Per-item provider failures do not stop later deletions; authentication, permission, and rate-limit failures stop the batch and mark remaining addresses not attempted. |
| `CLEVERREACH_DELETE_BLACKLIST_ENTRY` | Delete Blacklist Entry | Permanently remove one email address from the global CleverReach blacklist, or from a group blacklist when group_id is supplied. |
| `CLEVERREACH_DELETE_FILTER` | Delete Filter | Permanently delete a CleverReach filter or segment. This cannot be undone. CleverReach does not verify how the filter was created; the caller must confirm the selected filter is safe to delete. |
| `CLEVERREACH_DELETE_GROUP` | Delete Group | Permanently delete one CleverReach receiver group by ID. This operation cannot be undone, and CleverReach may reject deletion of a locked group. |
| `CLEVERREACH_DELETE_MAILING_CHANNEL` | Delete Mailing Channel | Permanently delete one CleverReach mailing channel/category. This cannot be undone. Only use an exact, owner-approved disposable channel ID; this toolkit has no channel-creation operation for recovery. |
| `CLEVERREACH_DELETE_MY_CONTENT` | Delete My Content | Permanently delete one CleverReach "My Content" item by exact ID. This cannot be undone; delete only an item that the current workflow created or that the owner explicitly approved. |
| `CLEVERREACH_DELETE_RECEIVER_ACCOUNT_WIDE` | Delete Receiver Account-Wide | Permanently delete one exact receiver at account level. This broader operation can remove the receiver from every group and cannot be undone. |
| `CLEVERREACH_DELETE_RECEIVER_ORDER` | Delete Receiver Order | IRREVERSIBLE: permanently delete one CleverReach receiver order globally or within a group using its internal id from LIST_RECEIVER_ORDERS, not the caller-defined order_id. Deleted order history cannot be restored by this action. |
| `CLEVERREACH_DELETE_RECEIVERS_ACCOUNT_WIDE` | Delete Receivers Account-Wide | Permanently delete a non-empty explicit list of exact receivers account-wide. This broader operation can remove them from every group and cannot be undone. |
| `CLEVERREACH_DELETE_REPORT` | Delete Report | Permanently and irreversibly delete one report and its historical analytics by exact report or mailing ID. This data cannot be recreated independently. All links contained in the report will stop working after deletion, including unsubscribe links. Requires explicit confirmation. |
| `CLEVERREACH_FILTER_RECEIVERS` | Filter Receivers | Return one bounded page of receivers matching temporary CleverReach filter rules. |
| `CLEVERREACH_GET_ATTRIBUTE` | Get Attribute | Return one CleverReach global attribute by ID. |
| `CLEVERREACH_GET_ATTRIBUTE_LIMITS` | Get Attribute Limits | Show the attribute limits applied to the connected CleverReach account. |
| `CLEVERREACH_GET_BLACKLIST_ENTRY` | Get Blacklist Entry | Check whether an exact email address is on the account-wide CleverReach blacklist and return its blacklist details when present. |
| `CLEVERREACH_GET_FILTER` | Get Filter | Get one CleverReach group filter or segment. |
| `CLEVERREACH_GET_FILTER_METRICS` | Get Filter Metrics | Return statistics or a receiver count for one CleverReach group filter. |
| `CLEVERREACH_GET_FORM_EMBED_CODE` | Get Form Embed Code | Return embeddable HTML, JavaScript, and CSS for an existing legacy CleverReach form, with optional branding controls. This provider endpoint is deprecated; use CleverReach Flow for new development and migrations. |
| `CLEVERREACH_GET_GROUP` | Get Group | Return one receiver group by its CleverReach group ID. |
| `CLEVERREACH_GET_GROUP_STATS` | Get Group Stats | Return either standard or advanced CleverReach statistics for one receiver group. |
| `CLEVERREACH_GET_MAILING` | Get Mailing | Return one CleverReach mailing campaign by its mailing ID. |
| `CLEVERREACH_GET_MAILING_CHANNEL` | Get Mailing Channel | Return one CleverReach mailing channel or category by ID. |
| `CLEVERREACH_GET_MY_CONTENT` | Get My Content | Return one CleverReach "My Content" item by ID. |
| `CLEVERREACH_GET_RANDOM_MAILING_RECEIVER` | Get Random Mailing Receiver | Return a random receiver from a CleverReach mailing audience for preview purposes. This does not send the mailing. |
| `CLEVERREACH_GET_RECEIVER` | Get Receiver | Return one receiver by ID or exact email address. Supply group_id for group-specific attributes; without it, group-specific information is empty. |
| `CLEVERREACH_GET_RECEIVER_ATTRIBUTES` | Get Receiver Attributes | Get attribute values for a CleverReach receiver, optionally in one group. |
| `CLEVERREACH_GET_RECEIVER_TAGS` | Get Receiver Tags | Return all tags currently set on one receiver, optionally filtered by origin. |
| `CLEVERREACH_GET_REPORT` | Get Report | Return one mailing report by report or mailing ID, including split-test versions when present. |
| `CLEVERREACH_GET_REPORT_STATS` | Get Report Stats | Return one selected statistics view for a mailing report, such as links, countries, clients, traffic, or daily activity. |
| `CLEVERREACH_LIST_ATTRIBUTES` | List Attributes | Return a locally bounded set of global attributes or local attributes for one CleverReach group. |
| `CLEVERREACH_LIST_BLACKLIST_ENTRIES` | List Blacklist Entries | Return a locally bounded set of entries on the global CleverReach blacklist, or on a specific group blacklist when group_id is supplied. |
| `CLEVERREACH_LIST_BOUNCED_RECEIVERS` | List Bounced Receivers | Return one bounded page of receivers with a bounce date and an opaque cursor for the next page. |
| `CLEVERREACH_LIST_BOUNCES` | List Bounces | Return one page of up to 500 account-wide CleverReach bounce records. Follow next_cursor until an empty terminal page returns no cursor. |
| `CLEVERREACH_LIST_FILTER_RECEIVERS` | List Filter Receivers | Return one bounded page of receivers matching a saved CleverReach filter. |
| `CLEVERREACH_LIST_FILTERS` | List Filters | Return a locally bounded set of CleverReach filters or segments for one receiver group. |
| `CLEVERREACH_LIST_FORMS` | List Forms | Return a locally bounded set of legacy CleverReach forms globally or for a supplied group. CleverReach marks both REST routes deprecated in favor of Flow, which is outside this toolkit. |
| `CLEVERREACH_LIST_GROUPS` | List Groups | Return a locally bounded set of receiver groups (lists) in the connected CleverReach account, optionally ordered by creation or change time. |
| `CLEVERREACH_LIST_MAILING_CHANNELS` | List Mailing Channels | Return a locally bounded set of CleverReach mailing channels, also called categories. |
| `CLEVERREACH_LIST_MAILING_LINKS` | List Mailing Links | Return the links CleverReach recorded for one mailing. List-shaped responses are locally bounded; provider summary objects and legacy strings are preserved. |
| `CLEVERREACH_LIST_MAILING_ORDERS` | List Mailing Orders | Return a locally bounded set of orders attributed to a CleverReach report or mailing. CleverReach documents no pagination for this endpoint. |
| `CLEVERREACH_LIST_MAILINGS` | List Mailings | Return campaigns filtered by delivery state, channel, or the state's time window. State 'all' returns one provider-bounded result; specific states return one page with a continuation cursor. |
| `CLEVERREACH_LIST_MAILING_TEMPLATES` | List Mailing Templates | Return locally bounded categories and either agency-managed or user-owned CleverReach templates. |
| `CLEVERREACH_LIST_MY_CONTENT` | List My Content | Return a locally bounded set of reusable CleverReach "My Content" items. |
| `CLEVERREACH_LIST_RECEIVER_EVENTS` | List Receiver Events | Return a locally bounded set of events recorded for one CleverReach receiver, either account-wide or in a specific group. CleverReach documents no pagination for this endpoint. |
| `CLEVERREACH_LIST_RECEIVER_GROUPS` | List Receiver Groups | Return a locally bounded set of group IDs to which a receiver is allocated, filtered by membership state. |
| `CLEVERREACH_LIST_RECEIVER_ORDERS` | List Receiver Orders | Return a locally bounded set of orders recorded for one CleverReach receiver, globally or in a specific group. CleverReach documents no pagination for this endpoint. |
| `CLEVERREACH_LIST_RECEIVERS` | List Receivers | Return one page of receivers in a CleverReach group, optionally filtered by subscription state, email addresses, or receiver IDs. |
| `CLEVERREACH_LIST_RECEIVER_TAGS` | List Receiver Tags | Return a locally bounded set of receiver tags already used in the account, optionally filtered by origin. |
| `CLEVERREACH_LIST_REPORT_RECEIVERS` | List Report Receivers | Return one page of receivers in a report for a delivery or engagement state such as opened, clicked, bounced, or unsubscribed. |
| `CLEVERREACH_LIST_REPORTS` | List Reports | Return one page of mailing reports filtered by date range, group, or channel. detail_level controls the richness of each report, not which reports match. |
| `CLEVERREACH_LIST_TAGS` | List Tags | Return one page of account tags or the account's supertags. Regular tags support group, origin, ordering, page_size, and a bounded continuation cursor. The limit field locally caps only list-shaped supertags and does not reduce provider API usage; a legacy string response is preserved. |
| `CLEVERREACH_REMOVE_RECEIVER_FROM_GROUP` | Remove Receiver From Group | Remove one exact receiver from one specified group. This does not claim to delete the receiver account-wide or remove it from any other group. |
| `CLEVERREACH_REMOVE_RECEIVERS_FROM_GROUP` | Remove Receivers From Group | Remove a non-empty explicit list of exact receivers from one specified group. This does not claim to delete them account-wide or remove them from other groups. |
| `CLEVERREACH_REMOVE_RECEIVER_TAGS` | Remove Receiver Tags | Remove specified tags from one receiver. An origin wildcard such as 'shop.*' removes every receiver tag from that origin. |
| `CLEVERREACH_SEND_MAILING_PREVIEW` | Send Mailing Preview | Immediately deliver a preview email for one mailing to the specified CleverReach account-user addresses. This sends real email and cannot be undone, but it does not launch the mailing campaign to its audience. |
| `CLEVERREACH_SET_RECEIVER_ATTRIBUTE` | Set Receiver Attribute | Update one attribute value on a CleverReach receiver at account or group scope. |
| `CLEVERREACH_SET_RECEIVER_STATUS` | Set Receiver Status | Activate or deactivate one receiver in a CleverReach group, changing whether the subscriber is active for mailings. |
| `CLEVERREACH_UPDATE_ATTRIBUTE` | Update Attribute | Update a CleverReach global or group-local attribute. |
| `CLEVERREACH_UPDATE_BLACKLIST_ENTRY` | Update Blacklist Entry | Update the comment on one account-wide CleverReach blacklist entry, identified by its email address. |
| `CLEVERREACH_UPDATE_FILTER` | Update Filter | Update a CleverReach filter or segment in one receiver group. |
| `CLEVERREACH_UPDATE_GROUP` | Update Group | Update the name, notes, lock setting, or backup setting of an existing CleverReach receiver group. Provide at least one of name, receiver_info, locked, or backup. Only explicitly supplied non-null fields are sent. |
| `CLEVERREACH_UPDATE_MAILING` | Update Mailing | Update the content, audience, sender, tracking settings, or tags of an existing CleverReach mailing campaign without sending it. Provide at least one of name, subject, sender_name, sender_email, content, receivers, settings, or tags. Only explicitly supplied non-null fields are sent. |
| `CLEVERREACH_UPDATE_MY_CONTENT` | Update My Content | Update supplied fields of one CleverReach "My Content" item. Omitted fields are not sent; provide at least one non-null field to update. |
| `CLEVERREACH_UPDATE_RECEIVER` | Update Receiver | Update lifecycle timestamps, profile attributes, tags, or orders for one receiver in a CleverReach group without changing the email. Provide at least one receiver field to update. Source is creation-only: CleverReach preserves the original source for an existing receiver. |
| `CLEVERREACH_UPDATE_RECEIVER_ORDER` | Update Receiver Order | IRREVERSIBLE MUTATION: replace the documented details of one CleverReach order item by its internal id from LIST_RECEIVER_ORDERS, not by the caller-defined order_id. CleverReach provides no revision history or automatic rollback. |
| `CLEVERREACH_VALIDATE_BLACKLIST_EMAILS` | Validate Blacklist Emails | Filter up to 1000 email addresses against the global or group CleverReach blacklist without changing blacklist state. By default the result contains addresses that are not blacklisted; set invert=true to return blacklisted addresses instead. |
| `CLEVERREACH_VALIDATE_RECEIVER_EMAILS` | Validate Receiver Emails | Submit up to 1000 email addresses and return CleverReach's valid-address result. The check excludes blacklisted addresses; group_id also requires active membership, and invert returns invalid addresses instead. This read-like POST changes no data. |

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Complete Code

None listed.

## Conclusion

### Use CleverReach from Atomic Agent
With your account connected, ask Atomic Agent to work with CleverReach in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

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

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

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent 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 CleverReach tools.

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

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