MCP Server Demo with Arista CloudVision

[!WARNING] Please note that this is not officially supported by Arista.

You might not want to do this in your production environment as it is not using a local LLM.

The free plan of Claude might cause anxiety!

Kudos to @burnyd for the inspiriation and for writing this blog post: https://danielhertzberg.net/posts/mcp-servers/

Expanding on that, I've added a few more API calls to be able to ask Claude to get connectivity monitor data, and create tags for Studios and dashboards, but obviously any API call can be added very easy with the @mcp.tool() decorator.
