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 Upload to URL through MCP without you sharing account credentials directly with the agent.

What is the Upload to URL MCP server, and what's possible with it?

The Upload to URL MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Upload to URL account. It provides structured and secure access to your hosted files and HTML pages, so your agent can upload files, retrieve file details, delete files, publish HTML pages, and check supported formats on your behalf.

  • Public file uploads: Have your agent upload a file and return its public CDN URL, expiration details, and remaining monthly credits.
  • File metadata retrieval: Let the agent retrieve current details and the public CDN URL for a previously uploaded file.
  • File deletion: Direct your agent to permanently remove an uploaded file from storage and its public CDN location.
  • HTML page publishing: Instruct your agent to publish raw HTML at a public URL using a page path you choose.
  • Upload requirement checks: Have your agent check accepted or blocked file extensions, plan size limits, and advertised security checks before uploading.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which Upload to URL 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 Upload to URL 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.
