OneCloud requests only dedicated cost and billing read access. Direct connections requiring business data, administration, write access or unverified wider permissions are blocked. Directory listings do not imply automatic connection.

Cloud services and AI subscriptions, in one view.

OneCloud brings a 144-service directory, 30 Korean entries, Open API, manual costs and read-only MCP into one cloud and AI cost platform. Collection methods vary by service.

Can external collectors and internal tools exchange data with OneCloud?

Yes. Project-scoped API keys let you read costs and usage or import externally collected records through OneCloud Open API. It supports original-ID updates, deduplication, import history and incremental exports. Provider API availability must be checked separately.

Can I enter subscription costs without an API?

Yes. Enter a company, service, usage date, amount, currency and note. You can edit or delete entries, and recorded amounts appear in dashboards and cost analysis. Entering an already imported cost counts it twice.

Can I query OneCloud costs from ChatGPT and Claude?

Yes. Connect the OneCloud MCP server, sign in to OneCloud and approve read access. Its 11 tools query cost summaries, daily costs, manual entries and connection status within your organization and project permissions. All tools are read-only.

COST ANALYSIS WITH AI

Review cost efficiency with Claude and ChatGPT.

Ask your familiar AI about the cloud, AI and subscription costs collected in OneCloud. Read-only MCP lets you review cost concentration and increases, and compare cost with billed usage where the provider supplies it.

Find cost concentration

Compare your highest-cost services and see how they changed from the previous period.

Review cost against usage

Compare available billed usage with cost and prioritize the services worth a closer review.

Plan the next month

Review spending plans with daily trends, anomaly records, and month-end and next-month estimates.

How it works

Connect the right collection method. Review it in one place.

Combine provider APIs, external collectors and manual records. Use OneCloud Open API to import automated data and read the cost and usage you need.

  1. 01

    Choose a provider and method

    Browse the service directory and check API collection, external collection, manual entry or estimated costs.

  2. 02

    Prepare credentials or an external source

    Follow the provider permission guide. External workflows use a project-scoped API key and source.

  3. 03

    Validate the collected records

    Validate imports with dryRun, then submit original IDs and Idempotency-Key. Check complete status in import history.

  4. 04

    Analyze, export and query with AI

    Review cost, usage and connection status. Export through Open API or query read-only data in ChatGPT and Claude via MCP.

FAQ

Frequently asked
before you start

Contact our team →
  • What data does OneCloud collect?
    OneCloud combines provider usage and billing APIs with cost and usage records imported through Open API or entered manually. Automatic collection varies by service and is labeled in the directory.
  • Do I need to install an SDK or change my code?
    Configure built-in collectors in the console. External collectors and internal systems can read or import JSON through OneCloud Open API. Any required metering and transformation runs in your collector.
  • How is this different from AWS Cost Explorer or Azure Cost Management?
    OneCloud normalizes multicloud spend against the FOCUS 1.2 spec so you can compare every cloud on one screen. Commitments, credits, and FX are treated in the same units, and AWS, Azure, GCP, NCP, and Vultr share the same grouping and the same allocation rules.
  • How is security handled when connecting?
    Set the authentication and read permissions required by each provider. Open API keys have explicit projects, scopes and expiry; they are shown once and stored only as hashes. Each call checks current account permissions, and keys can be revoked in the console.
  • Is Starter really free?
    Yes. Up to 30 sites, Cost Explorer, forecast, anomaly detection, alerts, and 6 months of data retention — every Starter feature is free forever. No credit card required.
