4. Connect your Raindrop.io account

Back in Cowork, ask the agent to connect to Raindrop.io or give it any Raindrop.io-related task.

For example, ask Cowork to:

  • "Save article to research collection"
  • "List bookmarks tagged AI research"
  • "Add highlights to saved tutorial"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Raindrop.io account is ready to use.

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

What is the Raindrop.io MCP server, and what's possible with it?

The Raindrop.io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Raindrop.io account. It provides structured and secure access to your bookmarks, collections, tags, and highlights, so your agent can save, find, organize, update, and remove web content on your behalf.

  • Bookmark saving: Have your agent save one or many web links with notes, tags, and collection placement.
  • Search and retrieval: Instruct your agent to search, filter, and sort saved bookmarks, then retrieve a specific bookmark and its highlights.
  • Collection organization: Let the agent create root or nested collections, rename or update them, and remove empty collections you no longer need.
  • Bookmark updates and cleanup: Direct your agent to edit bookmark details, move bookmarks between collections, replace tags, or send unwanted items to Trash.
  • Library overview: Have your agent list your collections and tags with bookmark counts so you can understand how your saved content is organized.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which Raindrop.io 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 Raindrop.io 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.
