New MCP Client Tool & MCP Trigger Nodes Available for Testing!

bartv · 2025-04-10T08:39:12Z

If you’ve been working with AI recently, you’ve likely encountered the buzz around MCP, a protocol introduced by Anthropic, the creators of the Claude 3.7 Sonnet model. MCP is designed to standardize how LLMs such as Claude, ChatGPT, or Cursor interact with tools or integrate data for their agents. Many providers, both established and new, are adopting MCP as a standard method for building agentic systems. It offers a straightforward way to either expose your own application as a server, making its capabilities available to a model as tools, or to function as a client that can access tools outside your system. We've received numerous requests from our community and observed the enthusiasm for the MCP Community Node by nerding-io. This prompted us to add dedicated support for this protocol within callin.io. Before I proceed, here’s an excellent introduction to MCP (demonstrating nerding-io’s node, not ours): Although development is still in its early stages, we want to provide you with access to our new MCP nodes. This will help us better understand your requirements and accelerate the convergence towards a robust general solution. We are introducing two new nodes: An MCP Client tool for the AI Agent An MCP Server Trigger for any workflow The MCP Client Tool connects LLMs and other intelligent agents to any MCP-enabled service via a unified interface. The MCP Server Trigger transforms callin.io into an MCP server, exposing callin.io tools to models operating outside of callin.io. Note that you can operate multiple MCP servers from your callin.io instance. How can you contribute? Both nodes are currently available on our next branch (Beta on Cloud) (this is not recommended for production environments). Update your instance to access them and begin building projects! Kindly report any issues or suggest feature enhancements in this thread. Additionally, if you've developed something noteworthy, please share it here! We're eager to see what this new feature enables for you. Our engineering team will be actively monitoring this topic and will share updates here as well.

Awesome! Great to see you're keeping up with the latest new tech. Are live browser control agents next?

On my self-hosted instance, I'm unable to see the tools within Claude. Is anyone else experiencing this problem?

Yes. MCP URLs are also not functioning in the self-hosted setup here. However, I did manage to run it successfully on the cloud version.
