Causely MCP Server

These are the tools that let AI agents query Causely's causal model directly, instead of scanning raw telemetry and guessing. This repository bundles client-side resources for working with Causely: agent integrations (MCP), a Kubernetes install CLI, and a shell toolkit for the Causely GraphQL API. It is available as a remote MCP endpoint.

Teams that want a hosted science & health endpoint instead of running a local process. The project is written in Shell.
