Common questions

Is Costory FinOps MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Costory FinOps MCP: the FinOps agent your team builds on, in Claude, Cursor or any MCP client

Costory is the FinOps agent your team builds on. Claude plus a single provider's MCP works for one person and one cloud. It breaks when you add more providers, more people, and more tools to maintain.

Multiple providers: AWS, GCP, Azure, LLM APIs and data clouds normalized and allocated to teams and features in one model, including allocation from telemetry (Kubernetes, Datadog, dbt).
Multiple users: one hosted setup with OAuth, per-user access and enterprise SSO, instead of local credentials and prompts per person.
Maintained for you: tools, skills and connectors kept up to date by Costory, so reorgs and new services don't break your agent.

Your agent finds savings, explains every change in spend and issues recommendations that your coding agent can implement. It works in Claude, Cursor and any MCP client, plus Slack. Customers include Alan, Deezer, Delivery Hero, Voodoo and Pennylane.

Pricing: Starter from $300/month, flat: unlimited users and data sources, and a fair use that 80% of customers never outgrow. Nothing is ever cut off, and agents connected through the MCP use no AI credits. 30-day free trial.

This repository is the open part: the agent skills and plugin packaging (Claude Code, Codex, Cursor) that teach an agent how to run FinOps workflows on top of the Costory MCP tools.

Endpoint: https://app-api.costory.io/mcp (streamable HTTP)
Auth: OAuth 2.1 in the browser. No IAM credentials, no Docker, no local server
Docs: docs.costory.io/features/mcp
Registry name: io.costory/finops on the official MCP Registry

What engineers ask it

"Why did our AWS bill jump last week? Which deploys line up with it?"
"Break down Kubernetes cost by namespace and team for the payments cluster."
"What is our total AI spend across OpenAI, Anthropic, and Bedrock this month, by team and model?"
"Split our shared Cloud SQL cost across teams by usage and publish it as a dimension."
"What is our cloud cost per active user, this month vs last month?"
"Create an alert if daily BigQuery cost goes above $2,000 and post it to our #finops Slack channel."
"Send the top 5 cost movers to Slack every Monday."

Connect the MCP

One click adds https://app-api.costory.io/mcp to VS Code or Cursor; the OAuth login opens in the browser on first use. Cursor deeplink, if you prefer to paste it: cursor://anysphere.cursor-deeplink/mcp/install?name=costory&config=eyJ1cmwiOiJodHRwczovL2FwcC1hcGkuY29zdG9yeS5pby9tY3AifQ%3D%3D

You need a Costory workspace with billing data connected. Starter from $300/month, flat; 30-day free trial.

Claude Desktop / Claude Code / Cursor / VS Code: add a custom connector pointing at https://app-api.costory.io/mcp, then complete the OAuth login in the browser window that opens. Per-client walkthroughs with screenshots are in the MCP docs.

This repo ships an .mcp.json you can copy:

"mcpServers": { "costory": { "type": "http", "url": "https://app-api.costory.io/mcp", "oauth": { "callbackPort": 8080 } } } }

Claude Desktop (developer config, claude_desktop_config.json), see alternative JSON config:

"mcpServers": { "costory": { "url": "https://app-api.costory.io/mcp" } } }

VS Code (.vscode/mcp.json):

"servers": { "costory": { "type": "http", "url": "https://app-api.costory.io/mcp" } } }

First prompt

Try "Use Costory to show my top cost drivers last month". The agent calls get_context, then query.

If your account has access to several organizations, get_context without a slug returns "Multiple organizations" with the list of slugs. The agent should call list_organizations (or read that list), ask which org to use, and pass that slug to get_context and the following tools. You can also name it upfront: "Use Costory org acme and show my top cost drivers last month".

MCP tools reference

The server exposes tools in five groups. Names and payloads are versioned; the API reference is the source of truth.

Group	Tools	What they do
Orientation	`get_context`, `search`, `get`, `suggest_groupby`, `suggest_usage_metrics`, `suggest_actions`	Discover dimensions, dashboards, metrics, and the right way to slice a question
Query	`query`, `list_metrics`, `list_virtual_dimensions`	Cost, usage, metric, formula, and budget queries with period-over-period comparison
Allocation	`create_virtual_dimension_draft`, `update_virtual_dimension_draft`, `preview_virtual_dimension_draft`, `publish_virtual_dimension`, `virtual_dimension_overlap_matrix`	Define custom cost axes with ordered CEL rules, preview, then publish
Reporting	`create_report`, `update_report`, `preview_report_widget`, `run_report_now`, `create_dashboard`, `update_dashboard`	Scheduled Slack, Teams, and email reports plus dashboards built from chat
Alerting and events	`create_alert`, `preview_alert`, `list_alerts`, `create_event`, `update_event`	Cost and budget alerts, and event annotations for correlation

Write tools act only inside your Costory workspace. Query scoping follows the calling user's workspace role.

FinOps skills

Skills are the workflow layer: each one encodes how to sequence the tools above for a class of question, so the assistant does not have to rediscover it.

MCP `skillId`	Use when
`bigquery`	BigQuery warehouse caveats (on-demand vs slots, physical vs logical, labels) plus the [BigQuery] dashboard template
`cost-change-investigation`	Explain a cost change with contribution, timing, usage, metric, event, alert, and terminology evidence
`query`	Cost, usage, metric, formula, and budget investigation. Explorer period-over-period only; hands off "what changed" to `reports` Explain
`virtual-dimensions`	Create, edit, preview, and publish custom cost axes with ordered CEL rules
`dashboards`	Create or extend dashboards with context-first widget inheritance and overview generation
`reports`	Scheduled Slack, Teams, and email reports, and preview-first DIGEST to explain last month's cost
`recipes`	Ready-made tracking designs matched to an outcome, then handed off to the skills above to build

Recipes currently cover BigQuery warehouse routing, GCP spend-based CUDs, budget-vs-actual dashboards, EC2 spike alerts, prod-vs-R&D splits, untagged coverage, marketplace spend, provider credits, namespace cost, compute drilldowns, and period-change explanation. See plugins/costory/skills/recipes/.

Cursor Marketplace packaging

This repo also ships a Cursor plugin layout next to the Claude Code marketplace:

.cursor-plugin/marketplace.json — multi-plugin marketplace manifest
plugins/costory/.cursor-plugin/plugin.json — Cursor plugin manifest
plugins/costory/mcp.json — hosted MCP at https://app-api.costory.io/mcp (OAuth in the client)
plugins/costory/assets/logo.png — plugin logo

Listed on cursor.directory/plugins/costory.

Install as a plugin (MCP connection + skills)

The plugin wires the MCP server and installs the skills in one step.

# Claude Code

claude plugin marketplace add costory-io/costory-finops-mcp-skills claude plugin install costory@costory

Codex

codex plugin marketplace add costory-io/costory-finops-mcp-skills codex plugin add costory@costory

Skills only, any agent ([skills.sh](https://skills.sh)): installs the seven skills into Claude Code, Cursor, Codex and other agents that read Agent Skills. Connect the MCP separately (see above).
