4. Connect your HackMD account

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

For example, ask Cowork to:

  • "Create a HackMD meeting notes draft"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your HackMD 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 HackMD through MCP without you sharing account credentials directly with the agent.

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

The HackMD MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your HackMD account. It provides structured and secure access to your personal and team notes, folders, trash, and account details, so your agent can create notes, read content, browse workspaces, move notes to trash, and restore deleted notes on your behalf.

  • Markdown note creation: Have your agent create Markdown notes in your personal workspace or a selected team workspace.
  • Note discovery and reading: Instruct your agent to list available notes and retrieve the full Markdown content of a chosen note.
  • Workspace and folder browsing: Let the agent view your HackMD profile, visible teams, and folders across personal or team workspaces.
  • Note cleanup: Direct your agent to move an unwanted personal or team note to the trash.
  • Deleted note recovery: Have your agent review trashed personal notes and restore one or more notes when needed.

FAQ

Frequently asked questions

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

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

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.

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.
