Documentation Overview

Talos MCP Server

A Model Context Protocol server for Talos Linux cluster operations — one thin tool, typed actions, zero runtime dependencies.

Companion to virtualbox-mcp-server: that server provisions the nodes, this one turns them into a Kubernetes cluster.

Design

One tool (talos) with typed actions for the cluster hot path — no CLI syntax needed:

Action	Does
`gen_config`	Generate cluster config + talosconfig (`cluster`, `endpoint`, optional `output_dir`)
`apply_config`	Apply machine config to a node (`node`, `file`, `insecure` for maintenance mode)
`bootstrap`	Bootstrap etcd on the control plane (once per cluster)
`kubeconfig`	Retrieve the cluster kubeconfig
`health`	Cluster health validation
`config_merge`	Merge a talosconfig context (never overwrites `~/.talos/config`)
`version`	Client or node version
`run`	Raw `talosctl` argv for the long tail (etcd, logs, reboot, upgrade…)
`resolve`	Report platform/install state without downloading or running

Backend: talosctl — the official gRPC client of the Talos machine API. An existing PATH install is always preferred; otherwise the correct binary for the host's OS/architecture is auto-installed from the official Sidero release, verified against GitHub's asset digest.

The full cluster recipe ships to clients in the MCP initialize handshake, so a fresh session can bring up a cluster without external knowledge.

Prerequisites

None beyond a hypervisor for the nodes. The server is a single Go binary; talosctl is auto-installed if absent.

Installing

Published on the official MCP Registry as io.github.bryanjbelanger/talos-mcp-server — that name is what registry-aware clients install by (current entry).

For hosts that support MCP Bundles, download the .mcpb from the latest release and open it. One bundle covers every platform; it carries a binary per (os, arch) and picks one at startup. The server needs no configuration — guest credentials and endpoints are per-call parameters, and talosctl is auto-installed on first use if the host has none.

Otherwise take the bare binary for your platform from the same release, or build it:

bash

go build -o talos-mcp-server .

Registration with Claude Code

Terminal

claude mcp add --scope user talos -- /path/to/talos-mcp-server

Verify with claude mcp list (✔ Connected), then restart the session.
