Costory's FinOps agent, in ChatGPT
Custom connector / MCP in ChatGPT (developer mode or workspace connector)
Why use ChatGPT for FinOps
ChatGPT is already where many engineers ask questions. With Costory's MCP server, those questions can be answered with your real cost data: spend from every provider, normalized and allocated to teams and features, with the deploys and metrics that explain changes.
Set up Costory in ChatGPT
ChatGPT can connect to remote MCP servers as a custom connector. A step-by-step ChatGPT guide is not yet published in the Costory docs; until it is, follow the generic remote MCP instructions in the docs.
What you can do
Investigate why spend moved, by team, service and environment.
Compare periods and see the deploys, incidents or provider events in the same window.
Create alerts, scheduled Slack reports (for example in #finops) and dashboards from the conversation.
Build and preview Virtual Dimensions to allocate spend when tagging is incomplete.
Example prompts
“Why did our cloud cost go up last week?”
“What does our OpenAI usage cost per feature this month?”
“Alert me if EC2 rises more than 10% vs the trailing 7 days.”
“Send a weekly report of the platform team's spend to #finops.”
FAQ
Is the Costory MCP server free to use with ChatGPT?
The MCP server is included in Costory plans (from €250/month, billed annually, 30-day free trial).
Do I need to run anything locally?
No. Costory is a hosted remote MCP server with OAuth. Your client connects directly to https://app-api.costory.io/mcp; no local proxy or Node.js is needed.
Can the assistant change my cloud resources?
No. Costory has no write access to your cloud accounts.
Context layer
Your assistant starts from your Context layer: how cost is allocated, who owns what, which metrics explain it, and what past investigations concluded.
Set up Costory with one prompt
Set up Costory for my company. Create my account, add Costory MCP, connect my cloud/LLM billing export with Terraform, then suggest the first three things to do.
The Costory MCP is hosted and requires a Costory account. The setup prompt creates one for you.

Costory notices
An anomaly is detected, any time of day.
Investigate anomalies in a Slack thread with the FinOps agent
When an alert fires in #finops or a team channel, reply in the thread and the FinOps agent investigates: which team, which service, which deploy.

Costory notices
A service runs well below its capacity for 30 days.
Rightsizing recommendations grounded in real usage
The agent compares what you pay for compute with what services actually use in CloudWatch or Datadog, then recommends instance sizes to the owning team, with the deploy history attached.

A developer is about to change a service.
Cost context in your terminal with Claude Code
