greenerplatform-mcp 0.1.0

MCP server exposing the GreenerPlatform deterministic reliability tools (kubectl-sentinel, incident-triage) to any AI agent.

greenerplatform-mcp

An MCP server that exposes the GreenerPlatform deterministic reliability tools to any MCP-capable agent — Cursor, Claude Desktop, VS Code, Windsurf, or your own client. Install once; the tools work everywhere.

It wraps two CLIs:

• sentinel_snapshot — a deterministic 15-dimension cluster-health snapshot (kubectl-sentinel).
• triage_incident — correlate an alert to cluster findings, build a causation chain, and return a P1/P2/P3 fix plan (incident-triage).

Neither tool carries an LLM or any vendor coupling. This server is a thin, neutral adapter. The agent reasons over the evidence the tools produce — it is bounded by the evidence, it does not guess at cluster state.

Prerequisites

• Python 3.10+
• kubectl-sentinel and incident-triage on your PATH (or set SENTINEL_BIN / TRIAGE_BIN to their locations)
• kubectl + jq for live cluster snapshots

Install

pipx install greenerplatform-mcp
# or: pip install greenerplatform-mcp

Configure your agent

Cursor — ~/.cursor/mcp.json (or a project .cursor/mcp.json):

{
  "mcpServers": {
    "greenerplatform": { "command": "greenerplatform-mcp" }
  }
}

Claude Desktop — claude_desktop_config.json:

{
  "mcpServers": {
    "greenerplatform": { "command": "greenerplatform-mcp" }
  }
}

Any other MCP client uses the same pattern: run greenerplatform-mcp over stdio.

Tools

Tool	Arguments	Returns
sentinel_snapshot	namespace?, context?, resource?	cluster-health JSON
triage_incident	alert, sentinel_json?, namespace?, context?	triage JSON (cause + fix plan)

If triage_incident is called without sentinel_json, it collects a fresh snapshot first (requires cluster access).

Version guard

A stale CLI silently emits fewer checks — for example, kubectl-sentinel 1.1.0 returns 10 of the 15 health dimensions. To keep an agent from reasoning over an incomplete snapshot, the server checks each CLI's --version and, if it is below the expected minimum, adds a non-destructive warnings array to the tool's JSON output:

{ "warnings": ["kubectl-sentinel 1.1.0 is older than the expected 1.2.1; output may be missing checks — update kubectl-sentinel"] }

The findings are still returned; the warning just flags that they may be partial. Set MIN_SENTINEL_VERSION / MIN_TRIAGE_VERSION to change the expected minimums.

Environment

Variable	Default	Purpose
SENTINEL_BIN	kubectl-sentinel on PATH	path to the sentinel binary
TRIAGE_BIN	incident-triage on PATH	path to the triage binary
GP_MCP_TIMEOUT	90	per-command timeout (seconds)
MIN_SENTINEL_VERSION	1.2.1	warn if the installed sentinel is older
MIN_TRIAGE_VERSION	1.2.1	warn if the installed triage is older

Releasing

Releases publish to PyPI automatically via GitHub Actions using Trusted Publishing (OIDC) — no API tokens are stored anywhere.

One-time setup (on pypi.org):

1. Sign in → Your projects → Publishing → Add a pending publisher.
2. Project name greenerplatform-mcp, owner GreenerPlatform, repo greenerplatform-mcp, workflow publish.yml, environment pypi.

To cut a release:

# bump version in pyproject.toml, commit, then:
git tag v0.1.0 && git push origin v0.1.0
gh release create v0.1.0 --generate-notes

The Publish to PyPI workflow builds, runs twine check, and publishes. After the first release, pipx install greenerplatform-mcp works for anyone.
