How to connect Cursor to your Datadog costs
Connect Cursor to your Datadog costs through Costory's FinOps MCP. Cursor gets Datadog spend allocated to teams and features, next to the deploys and metrics that explain it.
What you can ask Cursor about Datadog
“Why did our Datadog bill move this month?”
“Correlate the cost spike with Datadog traffic metrics.”
“Show Datadog CI spend by pipeline.”
“Which team owns most of this month's increase?”
“Set up a weekly Slack report of this spend for #finops.”
What Cursor sees
Costory ingests Datadog cost through Datadog usage and billing estimates (+ metrics and CI Visibility), normalizes it into one cost model alongside your other providers, and allocates it with products, usage types, teams; Datadog metrics next to cost. Through the MCP server, Cursor can query that allocated cost, compare periods, look up deploys and other events in the same window, and create alerts, reports and dashboards in Costory. It has no write access to your cloud accounts.
Good to know for this setup
Cursor reads Costory from its MCP settings: a server named costory with type "http" and the URL https://app-api.costory.io/mcp.
Datadog billing is an estimate until invoiced; compare against usage.
Set up in about 30 minutes
1. Connect Datadog to Costory. Follow the Datadog setup guide in the docs.
2. Map spend to owners. Use Virtual Dimensions to group accounts, projects, labels and tags into teams, products and environments, even where tagging is incomplete.
3. Add Costory to Cursor.
Add Costory to your Cursor MCP settings (mcp.json):
The first call opens a browser window to log in with your Costory account.

FAQ
Does Cursor get write access to my Datadog account?
No. Costory reads billing data you export to it. MCP actions create Costory objects (alerts, reports, dashboards, events) and never change your cloud resources.
What Datadog permissions does Costory need?
Read access to billing data only. The exact permissions are listed in the Datadog setup guide.
Where is the data stored?
Costory stores and processes data in the EU.
How much does it cost?
Plans start at €250/month (up to €10M annual cloud spend), billed annually, with a 30-day free trial. See pricing.

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.

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.
