<p align="center"><strong>A bridge that exposes any Spinnaker instance as an MCP server via the Gate API, written in Go.</strong></p>

It gives an LLM 37 tools to read and operate Spinnaker: applications, pipelines, executions, strategies and infrastructure.

![MCP Inspector connected to spinnaker-mcp started with TOOLSETS=readonly: only read tools are listed, and search_executions is selected with its arguments](https://raw.githubusercontent.com/GeiserX/spinnaker-mcp/main/docs/images/screenshots/tools-readonly.png)

## Features

- Applications and pipelines: list, read, trigger, save, update and delete pipelines, with revision history.
- Executions: list, search by trigger type, time range and status, cancel, pause, resume, restart a stage, evaluate SpEL.
- Deployment strategies: list, save and delete.
- Infrastructure: server groups, load balancers, clusters, firewalls, instances and console output, images, networks, subnets, accounts.
- Orchestration task status (deploy, resize, rollback).
- Bearer token, basic auth, x509 client certificate, or the session cookie of a Gate behind SSO (`spinnaker-mcp login`).
- stdio or HTTP transport; HTTP binds to `127.0.0.1` by default.
- Ships as an npm package (`npx spinnaker-mcp`), a Docker image and multi-arch Go binaries.

## Quick start

Add the server to your MCP client (Claude Code, Claude Desktop, Cursor):

```json
{
  "mcpServers": {
    "spinnaker": {
      "command": "npx",
      "args": ["-y", "spinnaker-mcp"],
      "env": { "GATE_URL": "https://spin-gate.example.com", "GATE_TOKEN": "your-token-here" }
    }
  }
}
```

Needs Node 18 or newer; the npm package runs the Go binary over stdio. Docker, local builds and the other credentials are in [Getting started](https://geiserx.github.io/spinnaker-mcp/getting-started/).
