nable
See where your cloud and AI bills go, and spend less. Runs in your terminal or inside Claude, Cursor, and VS Code.
You do not need to be a cloud-cost expert. nable does three things:
- Shows what you spend across AWS, Azure, GCP, Kubernetes, and 15+ AI and SaaS providers, in one place.
- Finds what you are wasting (idle servers, oversized databases, forgotten storage) and puts a dollar figure on each one.
- Fixes it, with your approval, by opening a pull request, then checks your next bill to prove the saving was real.
Everything runs on your machine, read-only, and your billing data never leaves it.
Try it
uvx nable scan
nable scan · profile prod
account 3521… · this account only
scanning 17 regions …
us-east-1 ......... 3 findings
eu-west-1 ......... 1 finding
────────────────────────────────────────────
$2,140/mo recoverable
$1,200/mo 3 idle NAT gateways, us-east-1
$610/mo 14 unattached EBS volumes (2.1 TB), us-east-1
$330/mo idle RDS instance (db.r5.xlarge, <2% CPU), eu-west-1
run `nable scan --spend` for the spend breakdown (uses Cost Explorer, ~$0.02)
Reads only free cloud APIs, so scanning never adds to your bill. uvx nable scan --demo runs on sample data with no account at all. Add --json for CI, or --spend for a deeper breakdown.
Use it in your editor
uvx nable runs as a local MCP server inside Claude, Cursor, and VS Code, on your existing Claude or Cursor membership, no API key and no per-token cost. Then ask:
- "Why did our AWS bill jump last month?"
- "How much are we spending on OpenAI and Anthropic?"
- "Which instances should we downsize?"
- "Open a Jira ticket for any waste over $200/mo"
Setup
Requires Python 3.11+. Need uv? curl -LsSf https://astral.sh/uv/install.sh | sh (or brew install uv).
uvx nable
The setup wizard finds AWS or GCP credentials already on your machine (an SSO login, a CLI profile, or default credentials), connects the one you pick, and configures your editor. Usually you never type a key.
Cursor one-click: Add nable to Cursor
Free forever for the local tool. A hosted version for teams (dashboards without a terminal, SSO, scheduled reports, always-on agents) is at getnable.com/pricing.
Manual editor config — only needed if setup didn't auto-configure
If finops setup doesn't auto-configure, run:
finops setup claude
Or add manually to claude_desktop_config.json:
With uvx (recommended):
{
"mcpServers": {
"nable": { "command": "uvx", "args": ["--python", "3.12", "finops-mcp"] }
}
}
With absolute path:
{
"mcpServers": {
"nable": { "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 runs finops-mcp in its own isolated environment. It's the most reliable option on corporate machines with managed Python installs.
Give your agent cost controls — a pre-action budget gate for coding agents
nable is not just tools your agent reads from. It is a pre-action gate your agent calls before it makes a cost-affecting change: it prices the change, checks it against your budget, and offers a cheaper path. It never applies anything itself. Propose-only, your agent proposes and a human approves.
Add one line to your agent's system prompt (Claude Code, Cursor, or any MCP client):
Before you apply any infrastructure change (a terraform apply, a helm upgrade, creating or resizing a resource) or start an expensive job, first call
check_action_policywith the action and the change (a terraform plan, a helm diff, or amonthly_delta_usd). Relay the verdict, the dollar impact, and the cheaper path when one is offered. Never apply ablockor anescalateaction; surface it to the human. nable is advisory and propose-only.
The gate returns allow / warn / block / escalate against your policy, the
monthly and annual dollar impact, and a spot alternative when the change is compute.
One-way doors (delete, terminate, buy a commitment) and over-budget changes always
escalate to a human.
And a budget for the agent itself. Run nable ai-budget once, it asks whether
you are on a flat plan or a metered API and what you pay, then remembers. On a flat
plan it tracks how much subsidized compute you pull for your fixed fee and warns
before you run low; on metered it gates on a dollar spend cap. check_ai_budget does
the same for the agent mid-task. It reads your Claude Code usage locally, nothing
uploaded. Add to your system prompt:
Before starting a large task, call
check_ai_budget. If it returnswarnorover, tell me where I stand before continuing.
It reports your real usage and burn rate against your budget, not a fabricated percentage of a plan's hidden rate limit.
Connectors (17) — every provider and what it pulls, plus Azure roles
| Provider | What it pulls |
|---|---|
| AWS | Cost Explorer (free tier) · CUR via S3 (Pro: 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 |
| Datadog | Usage Metering API v2: real dollar amounts |
| Snowflake | ACCOUNT_USAGE.METERING_HISTORY |
| Langfuse | Daily metrics API: model cost, token usage, trace volume |
| MongoDB Atlas | Invoice API |
| Twilio | Usage Records API |
| Cloudflare | Billing API |
| Vercel | Invoice API (Enterprise) |
| New Relic | Data ingest + user counts |
| Stripe | Fees and billing activity |
| Databricks | DBU usage and SQL warehouse spend |
| OpenAI | API usage and token spend by model |
| Anthropic | Claude API usage and token spend |
Azure roles. The Azure tools span three RBAC roles, granted to the service principal on each subscription (run finops doctor to check):
# repeat per subscription
az role assignment create --assignee <client-id> --role 'Cost Management Reader' --scope /subscriptions/<sub-id>
az role assignment create --assignee <client-id> --role Reader --scope /subscriptions/<sub-id>
az role assignment create --assignee <client-id> --role 'Monitoring Reader' --scope /subscriptions/<sub-id>
FAQ — free vs paid, providers, how it compares to Cost Explorer / Vantage
Is nable free? Yes. The terminal scan, every cost query, anomaly detection, all waste and rightsizing findings, and every connector are free forever. The agent team, ticket auto-creation, scheduled digests, and commitment recommendations are Pro.
Does my billing data leave my machine? No. nable is local-first and read-only by default. It reads your cost data on your machine and never uploads it, and you can confirm the no-egress behavior in the source.
What clouds and providers does it support? AWS, Azure, GCP, and Vertex; Kubernetes (Kubecost, OpenCost); AI and LLM providers (OpenAI, Anthropic, Bedrock, OpenRouter, LiteLLM, Modal, Together, Replicate, Cohere, Mistral, Langfuse); data platforms (Databricks, Snowflake, MongoDB); and SaaS (Datadog, New Relic, Cloudflare, Twilio, Vercel, Stripe).
How is it different from AWS Cost Explorer? Cost Explorer is AWS-only and console-bound. nable is cross-cloud, runs in your terminal and in Claude/Cursor, covers AI and GPU spend no cloud console shows, and proposes fixes as pull requests. nable scan also makes zero paid API calls by default.
Is there an open-source alternative to Vantage or CloudHealth? nable is an open-source (Apache-2.0), local-first alternative for cost queries, waste detection, rightsizing, and AI/GPU cost, running on your machine instead of a hosted SaaS.
Troubleshooting — install and setup fixes
finops-doctor # checks credentials, DB, network, audit log
finops setup claude # re-run editor 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 |

Your Python is older than 3.11. Install on 3.11+ (uvx --python 3.12 nable, or python3.11 -m pip install finops-mcp). |
cryptography build error / maturin failed |
uv tried to compile on Python 3.10. Use 3.11+: uvx --python 3.12 nable. |
| Corporate SSL errors | pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org finops-mcp |
| Works at home, not at work | Use uvx (corporate IT often strips custom PATH entries) |
