Spinnaker-MCP

A bridge that exposes any Spinnaker instance as an MCP v1 server via the Gate API, written in Go.

What you get

Everything is exposed over JSON-RPC. LLMs and agents can: initialize -> listTools -> callTool and interact with your Spinnaker deployments.

Quick-start

npm (stdio transport)

npx spinnaker-mcp

Or install globally:

npm install -g spinnaker-mcp
spinnaker-mcp

This downloads the pre-built Go binary for your platform and runs it with stdio transport.

Docker

docker run --rm -e GATE_URL=http://spin-gate:8084 -e TRANSPORT=stdio drumsergio/spinnaker-mcp:0.3.1

Local build

git clone https://github.com/GeiserX/spinnaker-mcp
cd spinnaker-mcp

cp .env.example .env && $EDITOR .env

go run ./cmd/server

Configuration

Authentication priority: Bearer token > Basic auth > x509 client cert > No auth.

Put them in a .env file (from .env.example) or set them in the environment.

Testing

go test -v -race ./...

Tested with Inspector. Before making a PR, make sure this MCP server behaves well via that tool.
