nable

Open-source, local-first FinOps. Ask your whole cloud and AI bill anything, get the fix as a pull request you approve, and prove the savings on your next invoice.

nable is an MCP server that runs on your machine and connects to your real AWS, Azure, GCP, Kubernetes, and SaaS billing. It answers cost questions in your editor, finds waste, drafts the fix for your approval, and verifies the savings landed. Your credentials stay in your OS keychain and your bill never leaves your control, so the no-egress claim is something you can read in the code, not just take on faith. The local agent is open and auditable; a hosted platform is available for teams.

Quick start

Requires Python 3.11 or newer. The uvx command below fetches a matching Python for you. If you take the pip path instead, check yours first with python --version (or python3 --version). On older Python, pip reports No matching distribution found for finops-mcp.

Step 1: Install and run the setup wizard

Need uv? It is not preinstalled on macOS or most Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh   # macOS / Linux
# or: brew install uv

Then:

uvx nable

No uv and don't want it? On Python 3.11+, pip install -U finops-mcp && finops welcome works too.

First run downloads dependencies, so give it a moment before the welcome screen appears.

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

Using Cursor? One-click install (opens Cursor and adds nable):

cursor://anysphere.cursor-deeplink/mcp/install?name=nable&config=eyJjb21tYW5kIjogInV2eCIsICJhcmdzIjogWyItLXB5dGhvbiIsICIzLjEyIiwgImZpbm9wcy1tY3AiXX0=

Then run finops setup once to connect a cloud account.

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

brew install uv && uvx nable setup

Step 2: Connect AWS (usually one keystroke)

finops setup aws

The wizard checks for AWS credentials you already have (an SSO login, an AWS CLI profile, or default credentials), shows you the account it found, and connects it when you confirm. If you use aws on this machine already, you will not type a single key.

Checking for AWS credentials on this machine...
✓ Found working credentials: profile 'default' -> account 1234
  Connect this account? [Y/n]

Only if no working credentials are found does it walk you through creating a read-only access key. Want the IAM policy to hand your platform team first? Run finops setup aws --iam-template.
