What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Esputnik through MCP without you sharing account credentials directly with the agent.

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

The Esputnik MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Esputnik account. It provides structured and secure access to your marketing automation tools, so your agent can perform actions like sending broadcasts, managing contacts, importing data, and handling push notifications on your behalf.

  • Bulk contact import and management: Quickly add or update thousands of contacts at once, check import status, and keep your lists up to date with minimal effort.
  • Broadcast and message control: Retrieve, review, and manage your marketing broadcasts and app inbox messages, ensuring your campaigns run smoothly.
  • Order and transactional data automation: Import and synchronize large batches of order data, keeping your marketing segmentation and triggers accurate and relevant.
  • Push and SMS notification management: Activate or deactivate push tokens, delete outdated SMS templates, and fine-tune your notification workflows directly through your agent.
  • Domain and integration setup: Register domains for web tracking or widgets, helping you expand and customize your communication reach seamlessly.

FAQ

Frequently asked questions

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

Yes, you can. Claude Cowork 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 Esputnik tools.

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

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
