Readme
Costfluent MCP server
An MCP server that lets an AI assistant read your Costfluent cloud cost data: costs over time, saved cost reports, budgets, anomalies, the savings queue, commitments and their coverage, and Kubernetes efficiency. It runs on your machine, talks to your assistant over stdin and stdout, and calls the Costfluent Public API with an API token you give it. It reads by default. Its write tools create and change annotations, cost reports, budgets, cost alerts and dashboards, acknowledge anomalies and set a savings finding's status and owner; it offers them only once an Owner turns on Let AI agents create and change objects under Settings, Organization, and only for the write capabilities the token carries. No tool deletes anything or touches a cloud account.
The same tools run from a terminal, a script or a CI job as the costfluent command line tool
(Command line).
