Which integrations are available for this server?

Allows bootstrapping etcd on the control plane as part of Kubernetes cluster initialization, via the dedicated bootstrap action. Enables turning Talos-provisioned nodes into a Kubernetes cluster, with capabilities for bootstrapping the control plane, retrieving the cluster kubeconfig, and validating cluster health. Provides tools for managing Talos Linux clusters, including generating and applying machine configs, bootstrapping etcd, retrieving kubeconfigs, checking cluster health, merging talosconfig contexts, and running raw talosctl commands.

How do I use talos-mcp-server?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@talos-mcp-server Bootstrap the Kubernetes cluster" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

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:

go build -o talos-mcp-server .

Registration with Claude Code

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

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

Bundled skill

skills/talos-cluster — the end-to-end procedure: provision nodes via the virtualbox MCP server, configure and bootstrap via this one. Install by copying (or symlinking) into ~/.claude/skills/.
