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

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

The CaptureKit MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your CaptureKit account. It provides structured and secure access to webpage capture, content extraction, website analysis, raw HTML, and account usage, so your agent can capture pages, extract web content, analyze websites, fetch HTML, and monitor usage on your behalf.

  • Webpage screenshots and PDFs: Have your agent capture any webpage as an image or PDF for visual reviews, records, or reports.
  • Structured content extraction: Let the agent extract page metadata, links, rendered HTML, Markdown, sitemap data, or cleaned main content.
  • AI website analysis: Direct your agent to summarize a webpage and identify its value proposition, features, categories, use cases, audience, or custom details.
  • Fast HTML retrieval: Instruct your agent to fetch raw webpage HTML for scraping, audits, or change monitoring without browser rendering.
  • Usage and quota checks: Have your agent check your current allowance, usage, API key status, quotas, and effective rate limits.

FAQ

Frequently asked questions

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

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