4. Connect your WebCrawlerAPI account

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

For example, ask Cowork to:

  • "Scrape competitor pricing pages weekly"
  • "Crawl documentation and extract broken links"
  • "Monitor product pages for content changes"

It will prompt you to authenticate and authorize access.

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

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

The WebCrawlerAPI MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your WebCrawlerAPI account. It provides structured and secure access to website crawling, page scraping, monitored feeds, and usage data, so your agent can crawl sites, extract page content, monitor website changes, manage feeds, and review costs on your behalf.

  • Website crawling: Have your agent start site crawls and check their progress, page results, errors, and observed costs.
  • Page scraping and extraction: Direct your agent to scrape a web page and return its content or structured information.
  • Website change monitoring: Let the agent create recurring feeds and review detected changes and recent monitoring activity.
  • Feed management: Instruct your agent to list monitored feeds, inspect their status, pause or resume monitoring, and permanently cancel feeds.
  • Usage and cost tracking: Have your agent check your available balance, request volume, and usage costs for a chosen date range.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which WebCrawlerAPI 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 WebCrawlerAPI 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.
