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 Nango through MCP without you sharing account credentials directly with the agent.

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

The Nango MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Nango account. It provides structured and secure access to your integrations, so your agent can perform actions like triggering syncs, managing connections, listing providers, and executing workflow actions across 250+ external APIs on your behalf.

Connection management and discovery: Effortlessly list all your existing Nango connections, view metadata, or retrieve connection information without exposing sensitive credentials.
Provider information and browsing: Ask your agent to list all available providers or fetch detailed configuration info for a specific provider, making it easy to discover and set up new integrations.
Triggering workflow actions: Direct your agent to execute custom workflow actions by specifying the connection, provider, and action identifiers—unlocking advanced automation across connected platforms.
Manual sync initiation: Have your agent trigger sync processes for any established connection, ensuring your data stays up-to-date across all integrated services.
Script configuration retrieval: Let your agent fetch Nango scripts configuration and triggers, enabling more tailored and automated integration flows.

FAQ

Frequently asked questions

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

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

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

Abhi Arya

Co-founder, Opennote

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.

Nirman Dave

CEO, Zams

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.

Ryan Yu

Founder, Extra Thursday

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.

With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
