nable, local-first FinOps

nable

FinOps MCP server for Claude and Cursor, across AWS, Azure, GCP, Kubernetes, and 15+ SaaS and AI providers.

The cost brain your AI agents check before they spend. Ask your whole cloud and AI bill anything inside Claude or Cursor, get genuine savings priced on your real rates, and the fix as a pull request you approve. One tool across AWS, Azure, GCP, Kubernetes, and 15+ SaaS and AI providers.

nable is FinOps that lives inside your AI. Ask Claude or Cursor about your cloud, SaaS, and AI spend and it answers with real numbers, priced on your actual rates, not list price. It finds the savings genuinely worth taking, proposes each fix as a pull request you approve, and checks the next bill to prove it worked. As your agents start spending real money, nable is the cost brain they check before they act.

Everything runs on your machine and your bill never leaves it, so the no-egress claim is something you can read in the source, not take on faith. Connect AWS or GCP by SSO login or a CLI profile and nable stores no secret at all, it just references your existing login; only keys you paste directly are encrypted in your OS keyring. It is read-only by default and never changes your cloud on its own. The local agent is open and auditable; a hosted platform is available for teams.

getnable.com · docs, quickstart, and the hosted platform

Free to start, runs on your Claude membership

uvx nable and ask away. nable runs as a local MCP server inside Claude Desktop, Claude Code, or Cursor, so your existing Claude Pro/Max or Cursor membership is the model. There is no Anthropic API key and no per-token cost. Tool calls count against your normal chat usage, the same as any long conversation, never a separate bill.

Cost queries, anomaly detection, and rightsizing findings are free forever. The agent team (the budget guard your agents check before they act, remediation PRs, and the learning loop) is Pro.

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.

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.
