FinOps knowledge for AI assistants: billing mechanics, commitment decisions and waste runbooks for AWS, Azure, GCP, AI and data platforms. By OptimNow.
Ask your assistant how to reduce a cloud bill, size a commitment, read a term sheet or allocate shared AI costs, and it answers from how billing works, with decision rules and worked examples, instead of general advice. The same files work in Claude, ChatGPT, Gemini, Cursor and any MCP-compatible tool. Open source, written by OptimNow from enterprise FinOps delivery, and aligned with the FinOps Foundation framework.
Each question below is answered by a file that exists in this repository today.

Neither the skill nor the connector can see your cloud account. For a question about your own resources, the answer is a detection query you run yourself, taken from the matching runbook.
The reference library is mapped to the 22 capabilities of the FinOps Foundation framework, grouped in its 4 domains. A filled square means at least one reference owns the capability; a grey square means the capability is covered inside another file; a dashed square is a known gap, listed with its reasoning in docs/ROADMAP.md.
FinOps Framework capability coverage: 21 of 22 capabilities covered by the reference library
This map is generated from the frontmatter of every reference file, and the CI pipeline fails when the committed map no longer matches the files (fcp-coverage.md).
The matrix reads the library by business need. Every cell comes from a named reference file, listed in the notes under the tables.

The reference finops-cloud-contracts.md covers negotiated spend commitments with the 3 hyperscalers: AWS Private Pricing (EDP and PPA), Azure MACC and the Azure Commitment Discount, and Google Cloud Minimum Commitment. It describes the 12 clauses of an enterprise agreement, where the discount shows in billing data, migration funding (MAP, Azure Accelerate, RaMP), Marketplace private offers as a commitment lever, the reseller channel, 9 intake questions to ask before advising, a 15-point review grid for a term sheet, the usual pitfalls and the timing of a renewal. A closing section covers Databricks and Snowflake commitments inside a cloud contract. Benchmarks come from public sources named in the file; the library carries no observed contract figure.
Also covered: SaaS renewal governance (renewal calendar, auto-renewal review) in finops-sam.md and the pre-renewal checkpoint and marketplace channel governance in finops-itam.md.
Not covered today: negotiation with AI providers (Anthropic, OpenAI and the hosted model vendors; the library covers their reservation mechanics, not their enterprise agreements), OCI Universal Credits beyond their mechanics, and colocation or hosting contracts.
A runbook is a step-by-step procedure for one specific waste pattern: the symptoms, a detection query you run in your own account, the fix in safest-first order, and the mistake to avoid. The library files them by provider and by waste category, and each one carries a confidence level that says whether a single signal is enough to act.
Waste runbook coverage: 43 runbooks across 8 waste categories and 4 scopes

to the right reference, the reference library and the runbooks. Installed in Claude, Kiro or through the installer for other tools, the guidance sits in the model's context before it answers. No code runs, no data leaves your machine.
tools the model calls when it decides to: list, search by FinOps capability or waste category, and fetch one reference or runbook. One URL to paste (https://mcp.optimnow.io/mcp), nothing to install. Tool calls go to a server OptimNow runs in Paris; see "Data handling" below.

answer time, never copied into these files.
The 2 delivery shapes behave differently: a loaded skill grounds advisory and symptom questions without a decision to make, while the connector depends on the model choosing to call a tool. What that means in practice, and when to use both, is in docs/CONCEPTS.md. Using a non-Claude model through an API, add the response contract from INSTALLATION.md to your system prompt so answers stay structured and billing-grounded.

More questions the library is written to answer, beyond the role list above:
then act. The skill does not recommend commitments to a team that cannot allocate its bill.
billing works (CUR columns, Azure cost-management semantics, BigQuery export, FOCUS conformance), with primary sources cited. Vendor savings and sustainability claims are read critically.
is often the right state; where cloud is the product, Run pays for itself in gross margin. The skill assesses maturity before recommending.
which business outcome does this protect or create.
its date and source; current prices route to OptimToken.
and a discipline file for agents, capacity and investment governance.
What the skill and the hosted connector run, send and fetch, so you can decide where each is appropriate. Full policy in PRIVACY.md.
markdown files read into the model's context. They run no code, call no network endpoint and carry no credentials. The runbooks contain detection queries (billing export SQL, CLI commands) that you run in your own cloud account; nothing in this repository reads a cloud account.
When the model calls one of the 7 tools, the tool arguments (a reference or runbook name, a section phrase, facet filters, a guide slug) travel over HTTPS to that server and the matching content comes back. The server requires no account and no authentication, holds no database and no per-user state, and serves the same public files as this repository. Its application log writes one line per request (method, path, status and request type, never the arguments); when a lookup matches nothing, it also writes the tool name and the arguments that missed, which are short strings the model writes and can include a word copied from your question. The server runs on Fly.io, primary region Paris, which holds that log stream, possibly with the client IP address, under its default retention. OptimNow does not sell, share or profile from it.
OptimToken is its decision in the conversation.
get_live_figures sends one HTTPS GET tooptimtoken.optimnow.io (an OptimNow site) for a guide's figures.json, carrying the guide slug and a cloud-finops-mcp User-Agent, nothing from the conversation. On the hosted connector the request leaves the server; with the PyPI package it leaves your machine. No other tool touches the network.
launcher, no credential read from your environment.
The library is updated weekly. Every Saturday an automated scan checks around 35 sources: cloud and AI provider release notes, billing changelogs and pricing pages, plus FinOps community publications. Each change is confirmed on the provider's own documentation and reviewed by a practitioner before it is applied. Every merge to main becomes a new plugin version in the Claude directory, and a version-tagged release ships the same content to PyPI and the MCP Registry. Watch or star the repository to be notified.
Practitioner experience is the highest-value contribution. Frameworks and vendor docs are already public; what is rare is "we tried X in production, this is what it billed". Corrections to billing mechanics, new or improved runbooks, real-world counter-examples and adversarial review of the recommendations are all welcome: the repository is opinionated, and it should also be falsifiable.
The full guide, including the repository structure, contribution types, process and conventions, is in CONTRIBUTING.md. If your change names another OptimNow tool (an MCP tool name, an endpoint URL, a provenance field), read DEPENDENCIES.md first.
Fork the repository and customise the reference files for your context: your cloud stack, your internal policies, your tag taxonomy, your negotiated rates. A fork gives you a stable base you can pull upstream updates into at your own pace. Typical customisations:
