Quick start

Step 1: Install and run the setup wizard

pip install finops-mcp && finops setup

The wizard walks through connecting your providers and auto-configures Claude Desktop at the end. No config file editing, no manual env vars.

On Anaconda? Use uvx (isolated, won't touch your Anaconda environment):

brew install uv && uvx finops-mcp setup

Step 2: Create an AWS access key (takes ~90 seconds)

When the wizard asks for your key:

1. Open: console.aws.amazon.com/iam/home#/users
2. Click your username → Security credentials → Access keys → Create access key → "Other" → Create
3. Paste both values into the wizard. It stores them and writes them to your editor config automatically.

Need a read-only IAM policy first? Run finops setup aws --iam-template and it generates one.

Step 3: Restart Claude Desktop and ask

What are my AWS costs this month?

Once you see a real cost breakdown, you're live. Also works with Cursor, Windsurf, and VS Code.

Step 4 (optional): Open the visual dashboard

finops serve

Opens a password-protected web dashboard at http://localhost:8080 your whole team can view in a browser, no Claude required. Share the URL and password with your manager or exec team.

7-day free trial, all features unlocked. No credit card required.

To add more providers later:

finops setup aws      # add another AWS account
finops setup azure    # add Azure
finops setup slack    # configure alerts
finops setup license  # activate a Team plan key
finops serve          # open the visual dashboard

---

What you can ask

• "What drove our AWS bill up 40% last month?"
• "Which Kubernetes namespace is over-provisioned?"
• "Are there any unusual cost spikes this week?"
• "Which EC2 instances should we downsize?"
• "Compare our cloud spend vs SaaS spend"
• "Create a Jira ticket for any EC2 waste over $200/mo"
• "Which team is spending the most on Datadog?"
• "What will our AWS bill look like next month?"
• "Show me RDS instances with low CPU that we could right-size"
• "What's our effective discount rate from Savings Plans?"

---

Visual dashboard

finops serve

Starts a local web dashboard your whole team can open in a browser, no Claude Desktop required. Share it with an exec, a FinOps analyst, or anyone who needs to see costs without using an AI interface.

What it shows:

• MTD spend and projected month total
• Cost trend: 3-month historical with run-rate projection
• Efficiency score: composite of waste, commitment coverage, anomaly response, and tag hygiene
• Savings opportunities: ranked by dollar impact, each with a one-click "Mark done" to track actions taken
• Savings pipeline: how much has been identified vs acted on vs verified

The dashboard reads from your local provider connections. Your data stays on your machine.

# Secure with a password (recommended when sharing on a network)
FINOPS_DASHBOARD_PASSWORD=yourpassword finops serve

# Default: auto-generates a random password and prints it at startup
finops serve

Light mode, dark mode, and 30/60/90-day lookback are built in.

How it works

Your credentials are encrypted with Fernet and stored in your OS keyring (macOS Keychain, Windows Credential Manager, or libsecret on Linux). They never leave your machine. Cost data is stored in a local SQLite database. We never see your data. Teams share findings via Slack alerts, Notion publishing, and CSV exports. No shared database required.

nable is read-only by default. It never writes to your AWS account unless you explicitly enable cleanup mode. Run finops setup aws --iam-template to generate a least-privilege IAM policy with exactly the permissions nable needs.

Manual Claude Desktop config

If finops setup doesn't auto-configure, run:

finops setup claude

Or add manually to claude_desktop_config.json:

With uvx (recommended):

{
  "mcpServers": {
    "finops": { "command": "uvx", "args": ["finops-mcp"] }
  }
}

With absolute path:

{
  "mcpServers": {
    "finops": { "command": "/usr/local/bin/finops-mcp" }
  }
}

Use the path from which finops-mcp.

Config file locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Why uvx? Claude Desktop is a GUI app and doesn't inherit your shell's PATH. uvx sidesteps this by running finops-mcp in its own isolated environment. It's the most reliable option on corporate machines with managed Python installs.

Provider	What it pulls
AWS	Cost Explorer (free tier) · CUR via S3 (Team: line-item granularity, savings plans, reservations)
Azure	Cost Management API · Advisor cost recs · VM rightsizing (Azure Monitor) · native budgets · forecast
GCP	Cloud Billing API + BigQuery export

Role	Unlocks
Cost Management Reader	cost queries, budgets, forecast, cost-by-dimension
Reader	Azure Advisor recommendations + VM list (rightsizing)
Monitoring Reader	VM CPU metrics (rightsizing)

# repeat per subscription

What nable actually does

nable is not just a connector that pipes billing data into Claude. It runs active analysis on your infrastructure and surfaces findings as tools Claude can reason about and act on.

AWS deep audit goes well beyond Cost Explorer. It pulls CloudWatch metrics for every running resource and flags waste that never shows up on your bill until it's too late: gp2 volumes that should be gp3 (20% cheaper, same performance), unattached EBS volumes, idle NAT Gateways costing $32/mo in base charges, RDS backup retention set way too high, CloudWatch Log Groups with no retention policy growing forever, and Lambda functions allocated 2x the memory they actually use. Think of it as Compute Optimizer plus the layer underneath it.

Anomaly detection uses z-score, CUSUM drift, and day-of-week seasonal normalization. When something spikes, it drills into Cost Explorer by tag and tells you which team, environment, or service drove it. Free tier shows findings in Claude; Team adds Slack/Teams alerts and auto-ticketing.

Rightsizing combines AWS Compute Optimizer with nable's own CloudWatch analysis. It gives you specific recommended instance types with estimated savings, not just a list of underutilized resources. Free tier shows recommendations in Claude; Team adds ticket auto-creation.

Commitment analysis (Team plan) models Savings Plans and Reserved Instance coverage against your actual usage. It shows your current effective discount rate, coverage gaps, and what you would save by purchasing additional commitments.

Troubleshooting

finops-doctor          # checks credentials, DB, network, audit log
finops setup claude    # re-run Claude Desktop configuration only

Symptom	Fix
Tools don't appear in Claude	Switch to uvx config or use absolute path
command not found: finops-mcp	Re-install with pip install finops-mcp or use uvx
AWS returns no data	Run finops setup aws. The wizard writes credentials to your editor config automatically.
Python 3.8/3.9 errors	nable requires Python 3.10+: python3.10 -m pip install finops-mcp
Corporate SSL errors	pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org finops-mcp
Permission denied	Install to user: pip install --user finops-mcp or use uvx
Works at home, not at work	Use uvx (corporate IT often strips custom PATH entries)
