01 · Install Talos Linux MCP Server

Claude Code

claude mcp add nosmoht-talos-mcp-server -- npx -y talos-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "nosmoht-talos-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "talos-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package talos-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.Nosmoht is GitHub-verified and matches the repo owner

03 · What Talos Linux MCP Server can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can list all available resource types and their aliases. Call this first to discover what can be queried, list all Talos services and their current state (running, stopped, health), list containers in a namespace (default: k8s.io for Kubernetes containers), and list running processes on target nodes.

The 23 tools it gives your agent

Extracted from the project's README - what Talos Linux MCP Server lets an agent do.

talos_resource_definitions: - List all available resource types and their aliases. Call this first to discover what can be queried.
talos_get: - Get or list any COSI resource by type (e.g. MachineStatus, Member, NodeAddress, Service). Supports maintenance-mode (insecure=true + endpoint).
talos_version: - Get Talos version info from target nodes. Supports maintenance-mode (insecure=true + endpoint).
talos_services: - List all Talos services and their current state (running, stopped, health).
talos_containers: - List containers in a namespace (default: k8s.io for Kubernetes containers).
talos_processes: - List running processes on target nodes.
talos_health: - Check cluster health (etcd, Kubernetes API, node readiness). Supports control_plane_nodes / worker_nodes override.
talos_logs: - Fetch recent service logs (last N lines, no follow).
talos_dmesg: - Read kernel ring buffer messages.
talos_events: - Fetch recent Talos runtime events (service changes, config changes).
talos_etcd: - Query etcd cluster: members (default) or status.
talos_etcd_snapshot: - Stream an etcd snapshot to a local file path.

talos_list_files: - List files and directories on a node filesystem.
talos_read_file: - Read file contents from a node filesystem.
talos_validate: - Validate a machine config (YAML/JSON) offline - no cluster connection.
talos_service_action: - Start, stop, or restart a Talos service (note: restarting etcd is not supported by the Talos API).
talos_reboot: - Reboot target nodes. Supports mode: default, powercycle, force.
talos_upgrade: - Upgrade Talos on target nodes. Supports preserve (default true), stage, force, reboot_mode.
talos_rollback: - Roll back the last upgrade on target nodes.
talos_patch_config: - Apply a targeted machine config patch (strategic-merge or RFC 6902 JSON Patch).
talos_reset: - Wipe and factory-reset target nodes (irreversible).
talos_apply_config: - Apply a complete machine config to a single node. Supports maintenance-mode (insecure=true + endpoint) for fresh-node bootstrap.
talos_meta: - Read, write, or delete META partition key/value pairs. Supports maintenance-mode (insecure=true + endpoint).
