@rainy-updates/cli

Rainy Updates is a deterministic dependency review and upgrade operator for Node monorepos and CI.

@rainy-updates/cli is built for teams that need fast dependency detection, trustworthy review, controlled upgrades, and automation-ready outputs for CI/CD.

Overview

Rainy Updates gives teams one dependency lifecycle:

1. check — detects candidate updates
2. doctor — summarizes the current situation
3. predict — estimates upgrade break risk before applying changes
4. review / dashboard — decides what should happen (interactive decision surface)
5. upgrade — applies the approved change set

Everything else supports that lifecycle: CI orchestration, advisory lookup, peer resolution, licenses, snapshots, baselines, and fix-PR automation.

For whom

• Node monorepo teams that want deterministic CI artifacts
• Engineers who want to review dependency risk locally before applying changes
• Teams that need fewer, better upgrade decisions instead of noisy automated PR churn

Why use it

• Detects updates quickly across single-package repos and workspaces
• Centralizes security, peer, license, health, and behavioral risk review
• Applies updates safely with configurable targets (patch, minor, major, latest)
• Enforces policy rules per package
• Supports offline and cache-warmed execution for deterministic CI runs
• Produces machine-readable artifacts: JSON, SARIF, GitHub outputs, and PR reports

Quick start

# 1) Detect what changed
bunx --bun @rainy-updates/cli check --workspace --show-impact

# 2) Summarize what matters
bunx --bun @rainy-updates/cli doctor --workspace

# 3) Decide in the dashboard
bunx --bun @rainy-updates/cli dashboard --mode review --plan-file .artifacts/decision-plan.json

# 4) Predict break risk
bunx --bun @rainy-updates/cli predict --workspace

# 5) Apply the approved plan
bunx --bun @rainy-updates/cli upgrade --from-plan .artifacts/decision-plan.json

Installation

Fast install (global)

Pick one:

bun add -g @rainy-updates/cli

npm i -g @rainy-updates/cli

pnpm add -g @rainy-updates/cli

Verify:

rup --version
rup mcp --help

Option 1: Bun runtime (recommended, no install needed)

bunx --bun @rainy-updates/cli check
bunx --bun @rainy-updates/cli audit --severity high
bunx --bun @rainy-updates/cli ci --workspace --mode strict

Option 2: Project dependency

npm install --save-dev @rainy-updates/cli
pnpm add -D @rainy-updates/cli
bun add -d @rainy-updates/cli

Then use via rup, rainy-up, or rainy-updates:

rup check
rainy-up doctor --workspace
rainy-updates upgrade --from-plan .artifacts/decision-plan.json

Option 3: Standalone binaries

Download pre-compiled binaries from GitHub Releases for:

• Linux x64 / arm64
• macOS x64 / arm64
• Windows x64

Each release includes:

• rup — human CLI
• rup-mcp — editor and agent integrations

Option 4: npx (compatibility)

npx @rainy-updates/cli check
npx @rainy-updates/cli audit --severity high

Note: Bun runtime is fastest. npm/npx are supported compatibility paths.

Configuration

Policy file

Control upgrade behavior with .rainyupdates-policy.json:

{
  "ignore": ["@types/*", "eslint*"],
  "packageRules": {
    "react": { "maxTarget": "minor", "target": "patch", "autofix": false },
    "typescript": { "ignore": true }
  }
}

Use it with:

rup check --policy-file .rainyupdates-policy.json

Config file

Configuration can be loaded from:

• .rainyupdatesrc
• .rainyupdatesrc.json
• package.json field: rainyUpdates

Environment

• .env files are auto-loaded by Bun
• .npmrc is read for private package registries
• FORCE_COLOR=0 disables colored output (useful for CI)

AI Agents (MCP)

Rainy Updates runs as a local MCP server for Claude Desktop, Cursor, and other MCP-capable agents to inspect dependency health.

5-minute setup

1. Install globally (rup) using the commands above.

2. Add this MCP JSON entry:

{
  "mcpServers": {
    "rainy-updates": {
      "command": "rup",
      "args": ["mcp"],
      "env": {
        "FORCE_COLOR": "0",
        "RUP_DEFAULT_CWD": "/Users/<you>/your-repo"
      }
    }
  }
}

3. If your client doesn't inherit PATH, use absolute binary path:

{
  "mcpServers": {
    "rainy-updates": {
      "command": "/Users/<you>/.bun/bin/rup",
      "args": ["mcp"]
    }
  }
}

4. Start asking:

• Run rup_context and confirm the effective cwd
• Run rup_doctor for this workspace
• Show high-risk updates with rup_review
• Check critical CVEs with rup_audit

Generate config JSON automatically:

rup mcp --print-config --client claude
rup mcp --print-config --client cursor
rup mcp --print-config --client generic

More client examples

Cursor example:

{
  "mcpServers": {
    "rainy-updates": {
      "command": "rup",
      "args": ["mcp"]
    }
  }
}

If your MCP client does not send cwd per tool call, you can also define a persistent default path in config:

{
  "mcp": {
    "cwd": "/Users/<you>/your-repo"
  }
}

Transport options

• Default: stdio via rup-mcp
• HTTP: rup-mcp --transport http --port 3741 --http-path /mcp
• Auth: rup-mcp --transport http --port 3741 --auth-token local-dev-token
• Reliability controls: --max-inflight 4 --max-queue 64 --tool-timeout-ms 30000 --initialize-timeout-ms 10000
• Diagnostics: --diag-json emits structured MCP diagnostics to stderr

MCP engine mode

Rainy includes a phased SDK migration path:

• RAINY_MCP_ENGINE=legacy (default): current production MCP engine
• RAINY_MCP_ENGINE=sdk: official @modelcontextprotocol/sdk engine path
• RAINY_MCP_ENGINE_FALLBACK=0: disable automatic fallback when sdk engine fails

Health badge

Use rup badge to add a live dependency health badge to any repository. This badge shows the current state of your dependencies and updates automatically.

How it works

1. Generates a GitHub Actions workflow that runs weekly (or on push to main)
2. Executes rup doctor to analyze your dependencies
3. Publishes the results as a JSON file via GitHub Pages
4. Shields.io renders the JSON as a dynamic badge in your README

For any user/repository

This feature works for ANY repository, not just this one:

# In your project directory
rup badge init --owner <your-github-username> --repo <your-repo-name> --readme

This will:

• Create .github/workflows/health-badge.yml (runs weekly + on push)
• Generate .artifacts/badges/README-badge-snippet.md with your badge markdown
• Optionally update your README.md with the badge

Setup requirements

1. Enable GitHub Pages in your repository settings:

   • Go to Settings → Pages
   • Source: GitHub Actions (not "Deploy from branch")

2. Run the init command:

rup badge init --owner <github-owner> --repo <repo-name> --readme

3. Commit and push the workflow file
4. The badge will update automatically on the schedule or when you push to main

Manual usage

Print only the badge URL:

rup badge url --owner <github-owner> --repo <repo-name>

Generate badge JSON manually (for CI):

rup doctor --badge-file .public/badges/health.json

Update frequency

The badge updates:

• Weekly (every Monday at 9 AM UTC) via cron schedule
• On every push to main/master branch
• Manually via workflow_dispatch in GitHub Actions UI

Example badge

The badge at the top of this README is generated using this same system.
