It can connect to outside tools through custom connectors, which use the Model Context Protocol (MCP). This guide explains how to connect Brevo to Muse using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a custom connector once, then ask Muse to work with Brevo in plain language. ## Also integrate Brevo with - [Claude Code](https://composio.dev/toolkits/brevo/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/brevo/framework/claude-cowork) - [OpenAI Agents SDK](https://composio.dev/toolkits/brevo/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/brevo/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/brevo/framework/codex) - [OpenClaw](https://composio.dev/toolkits/brevo/framework/openclaw) - [Hermes](https://composio.dev/toolkits/brevo/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/brevo/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/brevo/framework/google-adk) - [LangChain](https://composio.dev/toolkits/brevo/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/brevo/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/brevo/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/brevo/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/brevo/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/brevo/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/brevo/framework/autogen) ## TL;DR - Cross-app workflows across 1,500+ apps from a single plugin layer. - On-demand tool loading so Muse only loads the tools needed for the current task. - Programmatic tool calling through a remote workbench for complex, multi-step workflows. - Multi-account support so users can connect and switch between multiple accounts for the same app. - Shared account access so teams or agents can work through common business accounts and service connections. - Managed authentication with OAuth handling, credential storage, and token refresh managed by Composio. - Safer credential handling so app credentials stay outside the model context and tool responses. - User-level account isolation so actions run against the correct connected account instead of mixing user access. ## Connect Brevo to Muse ### Connecting Brevo to Muse You add Composio to Muse once as a custom connector, then connect Brevo from the chat. ## What is the Brevo MCP server, and what's possible with it? The Brevo MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Brevo account. It provides structured and secure access to your contacts, campaigns, templates, transactional email activity, SMS campaigns, and CRM records, so your agent can manage contacts, create campaigns, send emails, review messaging activity, and maintain company records on your behalf. - Contact and audience management: Have your agent create, update, delete, import, and review contacts, organize them into lists, and inspect configured contact attributes. - Email campaign creation and delivery: Direct your agent to create or update email campaigns, review campaign details, and send completed draft campaigns to their recipients. - Transactional email and templates: Let the agent create or update email templates, send or schedule transactional emails, and review transactional email events. - SMS campaign management: Instruct your agent to create SMS campaigns, review existing campaigns and their details, or delete campaigns that are no longer needed. - CRM and performance insights: Have your agent create, review, list, or delete companies, check contact campaign statistics, and inspect sender domains and their verification status. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BREVO_CREATE_A_COMPANY` | Create a company | Creates a new company record in your Brevo CRM. Companies can be used to organize contacts and deals, track business relationships, and manage customer accounts. You can add custom attributes, link existing contacts and deals, and set country codes for international phone numbers. Use this when you need to add a new business or organization to your CRM system. | | `BREVO_CREATE_CONTACT_LIST` | Create Contact List | Creates a new contact list (audience) in Brevo within a specified folder. Contact lists are used to organize and segment contacts for email campaigns, SMS campaigns, and marketing automation workflows. Use this tool when you need to: - Create a new audience segment for a marketing campaign - Organize contacts by specific criteria (e.g., geographic location, interests, purchase history) - Set up a list for newsletter subscribers, event attendees, or customer segments - Prepare a target audience before adding contacts or launching campaigns Note: You must specify a valid folder ID. Use Get Contact Lists to view existing folders and their IDs. | | `BREVO_CREATE_OR_UPDATE_EMAIL_TEMPLATE` | Create or Update Email Template | This tool creates a new email template or updates an existing one in Brevo. If a 'templateId' is provided, it performs an update; otherwise, it creates a new template. | | `BREVO_CREATE_SMS_CAMPAIGN` | Create SMS Campaign | This tool allows you to create a new SMS campaign in Brevo. You can specify the campaign name, sender, content, recipients (by providing list IDs, exclusion list IDs, or segment IDs), and optionally schedule the campaign for a specific time. You can also enable Unicode characters, add an organization prefix, and include unsubscribe instructions. | | `BREVO_DELETE_COMPANY` | Delete a company | Deletes a company from Brevo using its unique identifier. | | `BREVO_DELETE_CONTACT` | Delete Contact | Deletes a contact from Brevo by email, contact ID, external ID, phone number, WhatsApp ID, or landline number. Use the identifier_type parameter to specify the type of identifier when using ext_id, phone_id, whatsapp_id, or landline_number_id. | | `BREVO_DELETE_EMAIL_TEMPLATE` | Delete Email Template | This tool deletes an inactive email template from Brevo. You need to provide the 'templateId' of the email template you want to delete. Only inactive templates can be deleted. | | `BREVO_DELETE_SMS_CAMPAIGN` | Delete SMS Campaign | This tool deletes an existing SMS campaign. | | `BREVO_GET_ACCOUNT_INFO` | Get Account Information | Retrieves comprehensive information about the authenticated Brevo account.

Use this action to: - Verify account configuration and settings - Check available credits and plan type - Monitor transactional email relay status - Retrieve Marketing Automation tracker information. If credentials are missing or invalid, verify the Brevo connection is active before calling — retries will not resolve credential issues. If blocked by an 'unrecognised IP address' error, add the integration host's IP to the Brevo account allowlist. | | `BREVO_GET_ALL_CONTACTS` | Get all contacts | This tool retrieves all contacts from your Brevo account with pagination and filtering based on modification/creation dates, list IDs, segment IDs, and contact attributes.

Why doesn't Muse show a button to add my API key? Muse shows the button only when you ask it to open the secure credentials store. - Start a new chat. - Send the message from step 1 exactly as written. - If Muse asks for the key in the chat, do not paste it. Ask Muse to open the secure credentials store. ### 2. Why does the Composio connection fail after I add my API key? The key or the connector settings are not correct. - Copy the full key from the Composio dashboard. It starts with ck_. - Make sure the URL is https://connect.composio.dev/mcp and the header is x-consumer-api-key. - Remove the Composio connector in Muse settings, then do steps 1 to 3 again. ### 3. Why doesn't Muse use the Composio tools for Brevo? Muse may not pick the Composio connector for the request. - Ask Muse to list its Composio tools. - Name Composio and Brevo in your request, for example: Use Composio to connect to Brevo. - If it still does not work, start a new chat and try again. ### 4. Why does Muse ask me to connect Brevo again? Your Brevo connection expired or was removed. - Open the link Muse gives you and sign in to Brevo again. - Check that the Brevo connection shows as ACTIVE in the Composio dashboard. ### 5. What do I do if I pasted my API key into the chat? Treat the key as exposed. - Create a new API key in the Composio dashboard and delete the old one. - Add the new key in Muse's secure credentials store, not in the chat. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, Muse can access the Brevo MCP server through Composio to run the actions you authorize, using plain language in the chat. ## Complete Code None listed. ## Conclusion ### Way Forward Now that Brevo is connected, extend your setup by connecting the other apps you already use every day, so Muse can run true cross-app workflows end to end. - Connect Calendar to turn threads into scheduled meetings automatically. - Connect Slack or Teams to post summaries, approvals, and alerts where your team works. - Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs. - Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps. Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, Muse can coordinate multiple tools safely and reliably in one conversation. ## How to build Brevo MCP Agent with another framework - [Claude Code](https://composio.dev/toolkits/brevo/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/brevo/framework/claude-cowork) - [OpenAI Agents SDK](https://composio.dev/toolkits/brevo/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/brevo/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/brevo/framework/codex) - [OpenClaw](https://composio.dev/toolkits/brevo/framework/openclaw) - [Hermes](https://composio.dev/toolkits/brevo/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/brevo/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/brevo/framework/google-adk) - [LangChain](https://composio.dev/toolkits/brevo/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/brevo/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/brevo/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/brevo/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/brevo/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/brevo/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/brevo/framework/autogen) ## Related Toolkits - [Reddit](https://composio.dev/toolkits/reddit) - Reddit is a social news platform with thriving user-driven communities (subreddits).
